Thanks for the great library.

Using the ESP32 SDK, installed using Espressif installation guide results in a FILENAME already defined warning:

.../Documents/Arduino/libraries/AsyncTelegram2/src/serial_log.h:10: warning: "__FILENAME__" redefined
 #define __FILENAME__ (strrchr(__FILE__, '\\') ? strrchr(__FILE__, '\\') + 1 : __FILE__)

The warning indicates it is already defined in the ESP32 SDK at:

...Arduino15/packages/esp32/hardware/esp32/2.0.1/tools/sdk/esp32/include/newlib/platform_include/assert.h:38: note: this is the location of the previous definition
 #define __FILENAME__ (__builtin_strrchr( "/" __FILE__, '/') + 1)

Please change the define in serial_log.h to something else, e.g. __FILE_NAME__

1. Sometimes reboots (20 times in day)
2. Sometimes lost connection until manual reboot
3. OTA 8266 cause cyclic reboot

*I think there is a problem about parsing char * from JSON in function AsyncTelegram2::getNewMessage

I have 3 examples :

1 )

In MessageQuery when I print out
Serial.println(msg.callbackQueryData );
I got

XXXXXXXXX/sendMessage HTTP/1.0
Host: api.telegram.org
Connection: keep-alive
Content-Type: application/jso.....

But when I add 1 more member to struct TBMessage :
String callbackQueryData1;
And then I add 1 more line for parsing MessageQuery

message.callbackQueryData1 = updateDoc["result"][0]["callback_query"]["data"].as<String>();

Now Serial.println(msg.callbackQueryData1 ); print good result

2 )

In MessageText : I jot that JSON

{
  "ok": true,
  "result": [
    {
      "update_id": XXXXXXXX,
      "message": {
        "message_id": 123,
        "from": {
          "id": XXXXXXXX,
          "is_bot": false,
          "first_name": "XXXXXXXXXX",
          "language_code": "en"
        },
        "chat": {
          "id": -XXXXXXXX,
          "title": "XXXXXXXX",
          "type": "supergroup"
        },
        "date": XXXXXXXX,
        "text": "Gggh"
      }
    }
  ]
}

But when I tried to print msg.sender.firstName I got empty string and strlen(msg.sender.firstName) print 1

But when I add
String firstName1; to struct TBUser and then parse it
message.sender.firstName1 = updateDoc["result"][0]["message"]["from"]["first_name"].as<String>();;
I can print the first name as well

3 )

In MessageQuery when I tried to print callbackQueryID (char *)
Serial.println(msg.callbackQueryID); I got
back_data (what ???)

But if I convert callbackQueryID :
String callbackQueryID; in struct TBMessage
and parse as String :
message.callbackQueryID = updateDoc["result"][0]["callback_query"]["id"].as<String>();
I got right result.

So maybe there is a problem with parsing to char * ? can you please check it ? maybe we need to convert all char * to String in all structs ?

Maybe the error is because you only copy the pointer, you should deep copy with malloc and memcpy. But is better to use String more easy and more clean

Hi, thanks for this very useful library. I'm using it for a doorbell project. I am wondering if it is possible to send a photo to a group? I can't really see how looking through the source.

Thanks in advance.

Hello,
is it possible to "end" a bot after beginning it?
i'd like to be able to enable/disable bot in runtime, is it possible?
thanks

Can you give me an example for the command "sendCommand", please?!

best regaeds

I use your library AsyncTelegram2.h
Uploaded the lightBot.ino example. Through telegram, I turned on the LED and left it on. After a while I noticed that it went out. I turned it on again, but the situation repeated itself. Then I started the Serial Monitor and saw that after about 30-50 minutes the ESP8266 reboots with an Exception (2) error:
10:36:19.176 -> epc1=0x3ffed570 epc2=0x00000000 epc3=0x00000000 excvaddr=0x3ffed570 depc=0x00000000
or Soft WDT reset.
Here is the decoding of EspExceptionDecoder:

Hi!
I continue to deal with your library and faced the fact that I can not send a message to the telegram when any events occur. For example, write the following code:
void loop() { TBMessage msg; if(digitalRead(button)==HIGH) myBot.sendMessage(msg, " button=1"); }
but nothing comes in telegram. What am I doing wrong? At the same time, there is a connection with telegram.

Thanks for library! But i have little problem (using esp32, core 1.0.6):

It would be great to support "photo" messages. The library currently supports "document", but it is not able to process a message such as the following one, when you send a photo to the bot. Thanks for your time building this lib, Tolentino.

Hi Tolentino, considering the "hot" moment that the world is going through, do you think that telegram servers or itself could be banned by the international community? Is there a valid and free alternative to telegram-bots that can be integrated into small iot projects?
Hello and thank very much

Hi, if you look at the examples, in the setup you find this:

int64_t user id = 123456789;
myBot.sendTo (userid, welcome_msg);

this means that only the telegam user with id = 123456789 will be able to receive replies from your bot. Similarly, you can do the same by telling your bot to receive and process responses only from one or more selected telegram ID.

Hello

Thankyou So much!! I found that code on the example and with little changes, it is working!! i have not changed anything just very minute changes. There are no errors but the message is continuously generating. Here is the code..

Ciao Tolentino, attravero un PIR il cui pin è gestito tramite interrupt, vorrei che quando viene rilevato un movimento, il sistemi mi invii un messaggio di allert con tanto di foto. Ho scritto questa funzione ma non va:

void motion_detect() {
TBMessage msg;
if (flag_auto_detect) { // modalità motion detect inserita
if (motionDetected) { // rilevo movimento
Serial.println("beccato!");
char* filename = "/frame.jpg";
if (savePicture(filename)) {
if (sendPicture(msg, filename))
Serial.println("Picture sent successfull");
}
}
}
}

Quando il PIR rileva il movimento, vedo il flash accendersi ma la foto non viene spedita. Nella funzione che ho scritto ci sono errori? Come faccio al di fuori della funzione di telegram a gestire l'invio di messaggi quando si concretizzano degli eventi?
Grazie

So i'm trying to add some actions to make life easier:

• Build library
• Build examples
• CppLint

See my fork's actions for more details on that

Please share your thoughs on items below:

Build libarary:

What are the dependencies for Ardunio Uno ? The main issue was with functional - is that in <StandardCplusplus> library ?

Examples:

• Explicit library import fails for some reason. I need to use full github repo path instead.
• UNO fails, same reason as Library

CPP Lint:

not sure if linting is needed at this point (it fails with 197 issues). If you want, I can try to find some pull-request-review-style that would say which lines have isuses for easier processing.

Issues template

For easier troubleshooting (like instruction for stack trace decoding if present), board version, etc

Pull request template

6. Probably also sketch size comparison on pull request.
   https://github.com/arduino/report-size-deltas

Please reduce the number of Serial.println ();, now this is very much clogging up the serial port.

Release 2.0.8 Works with 2.0.1. However with 2.0.2, we get "Unable to connect to Telegram server"

Hi Tolentino, is it possible to send messages using telegram markup? in any chat if you put anything between ** its sent as bold
Also tried these and didn't work: https://core.telegram.org/api/entities
It would help a lot with the clarity of the information presented.
Thanks

Hello.
Thank you very much for your work
AsyncTelegram2 and I'm very glad that there is no stopping the main code when working.
There is one important issue: when using myBot.sendTo(userid, welcome_msg) is there a feedback function that would return "true" to the controller if the message was successfully sent and "false" if the message was not sent?
For me it is very important that if the message was not sent, resend until it is successfully sent.
Thanks!

I would like to send a photo to my bot when the esp32cam is powered on, then do nothing else (nothing in the loop function). That is, I would like it to send a photo without needing the /TakePhoto command. Thank you.

Ciao Tolentino
Usavo tantissimo il precedente ESPTelegramBOT che non so per quale ragione mi da sempre Message not delivered....mi viene il dubbio che ho aggiornato qualche libreria di IDE senza rendermi conto...
Lo hai eliminato? Forse perché usava ArduinoJson 5?
Mi sai aiutare?
Grazie
Mic

Ciao Tolentino, nei vari esempi nel setup() trovo questo blocco:

char welcome_msg[128]; snprintf(welcome_msg, 128, "BOT @%s online\n/help all commands avalaible.", myBot.getBotName()); int32_t chat_id = 436865110; myBot.sendTo(chat_id, welcome_msg);

se volessi spedire questo "messaggio di benvenuto" a 2 utenti Telegram, sai come posso fare?

Grazie 1000!

Hi, When using ESP32 & USE_CLIENTSSL = true, flash memory exceedes 100% and compilation fails.
Can you please explain what does that option means ?

My project uses an esp8266 to do two things, announce via broadcast UDP and via telegram message that the doorbell button was pressed. The UDP part works every time, but the telegram bot always work at startup but around 30 minutes after start, telegram messages are no longer delivered.
Check the screen capture, time is in 24hs format and I wrote the last message to simply show the timestamp.

Is there something I need to do to keep the telegram bot session alive?

Messages are sent using: myBot.sendTo(userid, "Timbre...!");

Thanks!

Hello,
How can we use Unicode in command?
When I use Unicode, the command disappear, it shows as normal text.

For example: /\u2010\u2030

Hi I noticed the code has Serial.prints dotted about the place. I've moved them into ifdef DEBUG ENABLE blocks to stop spillover into the Serial when not required.

when I sending a message to a bot on the group the bot answers directly to the sender in private message but not to the group
seems bot answers to the senderId instead of chatId
is it an issue?

I have esp8266 and I want to understand how to use this library.

1. How can I listen and send message to telegram group by group id ? I saw that example https://github.com/cotestatnt/AsyncTelegram2/blob/main/examples/echoBot/echoBot.ino and that send message to channel , not group

2)How can I send message with inline keyboard like :
https://github.com/witnessmenow/Universal-Arduino-Telegram-Bot/blob/master/src/UniversalTelegramBot.cpp#L607

3)What is the difference between that library and https://github.com/witnessmenow/Universal-Arduino-Telegram-Bot in esp8266 please>

4)When I add user to group there is automatically message "You added XXX" How can I handle that message and send to group "Welcome XXX" ?

5)With esp8266 can I really by async and not blocking another job while I send message or get message from Telegram? Esp8266 has only 1 core.
I ask because in Universal-Arduino-Telegram-Bot I got lot of software watchdog reset ,and I think it's because this library is not async.

Thank you!

See https://core.telegram.org/bots/api => setMyCommands

Thanks and best regards
Daniel

Finally I got a time for testing the sketch. It has been accommodated for GSM network usage. The Telegram connection test was passed successfully (local terminal report). The "welcome" interactive message reaches to the bot. But the actual update always falls, being treated as "File is unavailable. Maybe size limit 20MB was reached or file deleted", due to boolean "msg.document.file_exists" being false. In meantime the test print of the string "msg.document.file_path" variable on monitor return blank string.

Hi !
About AsyncTelegram2::getNewMessage :

1- Do you get each time 1 message only and the next message will come in the next loop?

2- https://github.com/cotestatnt/AsyncTelegram2/blob/master/src/AsyncTelegram2.cpp#L190
Please make 12 as constant strlen(""update_id":")

3- Why do you comment out
https://github.com/cotestatnt/AsyncTelegram2/blob/master/src/AsyncTelegram2.cpp#L198

4- Why do you use "6"
https://github.com/cotestatnt/AsyncTelegram2/blob/master/src/AsyncTelegram2.cpp#L192
Can you please do that with constant value with name ?

About inline_keyboard :

When I use:

      String keyboardJson = "{\"inline_keyboard\": [[{ \"text\" : \" press here please \", \"callback_data\" : \"press1\" },{ \"text\" : \" press here please \", \"callback_data\" : \"press2\" }]]}";

      myBot.sendMessage(msg, "This is inline keyboard:", keyboardJson);

So when the user press on "press here please" in Telegram I see the "loading cycle" around 20 seconds even the message already arrived to esp. Maybe is there any ack you should send back to Telegram to stop this loading cycle?

Loading cycle like here

By the way , I saw important commits after last release , when do you make new release ?

Hi,
i ve given a look on LIGHTBOT AsyncTelegram2 and before to begin i ve some questions:

1. on AsyncTelegram1 library you wrote to read https://sites.google.com/a/usapiens.com/opnode/time-zones to set the correct time zone, shall i do the same with AsyncTelegram2 ?
2. #define USE_CLIENTSSL true -> i dont know if i must use external SSL library or not, what could be difference?
3. what are the most used classes or functions of this library? example, i think:
   -> msg.sender.username; // userID and is it as String?
   -> msg.text; //text message, as String?
   if i already have userID, how can i send message to him without answering to a message at Restart?
   is it correct:

myBot.sendMessage([sender_id], "NodeMCU restarted!");

and if so, is Sender_id a String or a int64_t or what else?

i m going using NodeMCU esp8266 and ESP32 for my sketch.
Thank you for help and sorry for my silly questions, i m trying to improve

EDIT: i see in other example EchoBot other commands:

myBot.sendTo(userid, welcome_msg);
myBot.sendToChannel(channel, message, true);
myBot.getBotName()

what's difference between sendTo and sendMessage? how to chose between them?
can we have a list of these commands?

Is this version 2 already available into Arduino Libraries?

Hi,
I see that if the bot have 1000 users, so any messages from all users will be sent to all devices.

My purpose is to have multiple users using the same Bot(same token) and devices are assigned to different chat_id(users) rather than 1 device one Bot. This is too tedious.

I want to use the same token to manage 20+ esp8266 relay.
But it shows conflict error in getUpdates().
"error_code": 409, "description": "Conflict: terminated by other getUpdates request; make sure that only one bot instance is running"

Is there any way to filter update based on chat_id(user_id)?

Thanks;

Can you add please that option?
Make a phone call via Telegram.

It is so needed.

How can we implement TOTP on our bot ? For that there is TOTP library in Arduino and then it is saying to generate "hmac" key. or how can we limit the IP access like telegram_ip_lower or telegram_ip_upper are there any such function under Async library to limit the IP's ?

Next, can we limit the ESP32 board to sepcific IP's ? as telegram bots can be accessed by any user around the world hence, all we can do is to limit the IP access or is there any other method ?

I believe it would be much better if this had a more flexible and clear implementation.

I don't know much about programming, so I apologize in advance for my overuse of strings and possible bugs in the code, but here's an example idea to make the implementation clearer.

bool AsyncTelegramBot::sendTextMessage(int64_t chat_id, String text, String parse_mode = "Default", String entities = "", bool disable_web_page_preview = false, bool disable_notification = false, int32_t reply_to_message_id = 0, bool force_reply = false, bool allow_sending_without_reply = true, String reply_markup = "")
{
    if (!strlen(text.c_str()))
        return false;

    if (chat_id == 0)
        return false;

    DynamicJsonDocument root(BUFFER_BIG);
    // Backward compatibility
    root["chat_id"] = chat_id;
    root["text"] = text;

    if (parse_mode != "Default")
        if (parse_mode == "Markdown" || parse_mode == "MarkdownV2" || parse_mode == "HTML")
            root["parse_mode"] = parse_mode;

    if (disable_web_page_preview)
        root["disable_web_page_preview"] = disable_web_page_preview;

    if (disable_notification)
        root["disable_notification"] = disable_notification;

    if (reply_to_message_id != 0)
        root["reply_to_message_id"] = reply_to_message_id;

    if (allow_sending_without_reply)
        root["allow_sending_without_reply"] = allow_sending_without_reply;

    if (strlen(entities.c_str()))
    {
        StaticJsonDocument<BUFFER_MEDIUM> doc;
        deserializeJson(doc, entities);
        JsonObject myEntities = doc.as<JsonObject>();
        root["entities"] = myEntities;
    }

    if (strlen(reply_markup.c_str()) || force_reply)
    {
        StaticJsonDocument<BUFFER_MEDIUM> doc;
        deserializeJson(doc, reply_markup);
        JsonObject myKeyb = doc.as<JsonObject>();
        root["reply_markup"] = myKeyb;
        if (force_reply)
        {
            root["reply_markup"]["selective"] = true,
            root["reply_markup"]["force_reply"] = true;
        }
    }

    root.shrinkToFit();

    size_t len = measureJson(root);
    char payload[len];
    serializeJson(root, payload, len);

    debugJson(root, Serial);
    const bool result = sendCommand("sendMessage", payload);
    return result;
}

When replaying a message that the bot sent, it stops working, not responding to any more messages.

Looking at the serial, the following information is printed:

{"ok":true,"result":[{"update_id":289757217,
"message":{"message_id":50,"from":{"id":251360319,"is_bot":false,"first_name":"Kwecko","username":"kwecko","language_code":"pt-br"},"chat":{"id":251360319,"first_name":"Kwecko","username":"kwecko","type":"private"},"date":1645725307,"reply_to_message":{"message_id":47,"from":{"id":5254501027,"is_bot":true,"first_name":"Kdesenvbot","username":"kdesenvbot"},"chat":{"id":251360319,"first_name":"Kwecko","username":"kwecko","type":"private"},"date":1645725268,"text":"Os comandos dispon\u00edveis s\u00e3o:\n\n /temperatura : Para verificar a temperatura\n /humidade : Para verificar a humidade\n /pressao : Para verificar a press\u00e3o\n /gas : Para verificar o g\u00e1s\n /mac : Para verificar o endere\u00e7o MAC\n /ip : Para verificar o endere\u00e7o IP do ESP32\n /timeboot : Tempo em que o ESP est\u00e1 ligado\n /version : Informa a vers\u00e3o do Sistema\n /esptemp : Informa a temperatura do ESP\n /help : Listar os comandos dispon\u00edveis","entities":[{"offset":31,"length":12,"type":"bot_command"},{"offset":31,"length":12,"type":"bold"},{"offset":76,"length":9,"type":"bot_command"},{"offset":76,"length":9,"type":"bold"},{"offset":115,"length":8,"type":"bot_command"},{"offset":115,"length":8,"type":"bold"},{"offset":152,"length":4,"type":"bot_command"},{"offset":152,"length":4,"type":"bold"},{"offset":181,"length":4,"type":"bot_command"},{"offset":181,"length":4,"type":"bold"},{"offset":219,"length":3,"type":"bot_command"},{"offset":219,"length":3,"type":"bold"},{"offset":264,"length":9,"type":"bot_command"},{"offset":264,"length":9,"type":"bold"},{"offset":308,"length":8,"type":"bot_command"},{"offset":308,"length":8,"type":"bold"},{"offset":348,"length":8,"type":"bot_command"},{"offset":348,"length":8,"type":"bold"},{"offset":389,"length":5,"type":"bot_command"},{"offset":389,"length":5,"type":"bold"}]},"text":"/help","entities":[{"offset":0,"length":5,"type":"bot_command"}]}}]}

this message is printed constantly. Does anyone have any suggestions on how to get around this problem?

Thanks

how can i change the parse_mode to "MarkdownV2" or "HTML"?

best regards
Daniel

Please add the variable languageCode to AsyncTelegram2.cpp :: line 210+

message.sender.languageCode = updateDoc["result"][0]["message"]["from"]["language_code"];

i tried to run your example code & i succesfully created the bot but on serial monitor i am it is saying "Unable to connect to telegram server" i have tried changing library version and Pin configuration but still the error is same. Can you please look into it ?

I run this library in esp8266 and I got reboot 2 reboot in 5 minutes (I don't know how to print core dump) but here is the log of Hardware WDT Timeout when the library cannot connect to Telegram server.
That happened in idle ...I didn't get any new message.

I know that is Hardware WDT Timeout because of this function that run in setup

void send_startup_reason() {
  String doc = "Startup  ";
  struct rst_info* pRstInfo = system_get_rst_info();
  switch (pRstInfo->reason) {
    default: doc += "Unknown"; break;
    case REASON_DEFAULT_RST: doc += "Power On (normal)"; break;
    case REASON_WDT_RST: doc += "Hardware WDT Timeout"; break;
    case REASON_EXCEPTION_RST: doc += "Exception"; break;
    case REASON_SOFT_WDT_RST: doc += "Software WDT Timeout"; break;
    case REASON_SOFT_RESTART: doc += "Soft Restart"; break;
    case REASON_DEEP_SLEEP_AWAKE: doc += "Deep Sleep Awake"; break;
    case REASON_EXT_SYS_RST: doc += "External System Reset"; break;
  }
  myBot.sendTo(MY_USER_ID, doc);

Hers is the log :

Thank you for your new library, the old one was already good but this is even better.
You can answer in italian if you want, I understand it but can't write it very well.

I have some of these PIR in the photos and the output goes HIGH for up to 5min (user regulated) after movement is detected.

Do I just need to change the following lines or is there a better way?

// PIR Motion Sensor setup
  pinMode(PIR_PIN, INPUT);

and

// PIR motion detected 
    // could be on interrupt, but PIR sensor usually keep signal HIGH for enough time
    if(digitalRead(PIR_PIN) == HIGH) {   
      currentPict = 0;
      waitPhotoTime = 0;
      char message[50];
      time_t now = time(nullptr);
      tInfo = *localtime(&now);
      strftime(message, 50, "%d/%m/%Y %H:%M:%S - Motion detected!", &tInfo);
      Serial.println(message);
      myBot.sendTo(userid, message);
    }

Ciao Tolentino, ben ritrovato e auguri di buon Natale e anno nuovo!

Volevo dirti che l'IDE arduino non notifica l'aggiornamento della tua libreria alla versione 2.0.5 e che quindi l'update va fatto manualmente. Effettuando l'aggiormento alla versione 2.0.5 e scaricando lo zip "AsyncTelegram2-2.0.5.zip" arduino però mi notifica che la versione installata è ancora la 2.0.4. Come mai?
Inoltre nel file "library.properties" leggo 2.0.4.
So cercando di usare la formattazione bold nel testo di risposta di un messaggio, ma sia in html che markdown v2, i messaggi così formattati non vengono inviati.
Grazie e ciao

Hello Tolentino, welcome back and best wishes for a Merry Christmas and New Year!

I wanted to tell you that the arduino IDE does not notify the update of your library to version 2.0.5 and that therefore the update must be done manually. By upgrading to version 2.0.5 and downloading the zip "AsyncTelegram2-2.0.5.zip" arduino, however, notifies me that the installed version is still 2.0.4. How come?
Also in the "library.properties" file I read 2.0.4.
I know trying to use bold formatting in the reply text of a message, but in both html and markdown v2, messages so formatted are not sent.
Thanks and bye

Ciao Tolentino, provando l'esempio ESP32-CAM che hai aggiornato qualche giorno fa (ma succedeva anche con le precedenti versioni), noto che se si inviano messaggi molto ravvicivati (qualche secondo) la scheda (ESP-32 CAM) pur ricevendo il messaggio non scatta e di conseguenza non invia la foto. E' come se si perdesse dei messaggi. Idee?

Hi Tolentino, trying the ESP32-CAM example that you updated a few days ago (but it also happened with the previous versions), I notice that if you send very close messages (a few seconds) the card (ESP-32 CAM) while receiving the message does not take and consequently does not send the photo. It's like missing messages. Ideas?

Please help. How do I constantly get connection status from telegram?

Good day Tolentino,
I dont know if anyone had the same issue, I found no info, so I thought to ask you directly.

When I use
myBotgetNewMessage(msg)

I do not receive messages on my ESP8266 from a groupchat where my bot is an admin. Also my bot's privacy was set as public, even if I start the message with "/xxxxx" or "@MYBOT" I do not receive any message typed in a group.

I do receive the messages on the esp8266 from direct message to my bot.
I would like to be able to use a group, for transparency and to have all messages in one place, as a security and automation of my home where me and my family can message the bot to open door or gates or get alarms.

Thank you.

Can I edit mesage by message Id with that library?

When for some reason the connection to the bot router is lost when trying to connect, the ESP 32 cycle becomes 20 seconds. How can I turn it off when there is no connection?

P.S. I don’t know English well, translated through Google )
