I think it has to do with the bot.getUpdate command, because if i delete it then i don't get a error message. Plz Help :)

hi
i am thanks for your help to peaple for publishin your good project
in this code i want give data from google Sheet and send data in telegram bot,
i use this project to give data from google sheet:
https://github.com/lorol/Googlesheet_DHT_simple
and use this project for recive and send data from telegram robat:
https://github.com/witnessmenow/Universal-Arduino-Telegram-Bot
i use esp8266
i merge two above project but i cant compile because i give error , because two project use WiFiClientSecure.h library , and same client :(

i changed the client name , and code ha been compiled, but in serial monitor , program crashed
i changed "HTTPSRedirect* client= nullptr;" to "HTTPSRedirect* test= nullptr;" and change every client in the code to test,
i also change below code, in the next change

WiFiClientSecure client;
UniversalTelegramBot bot(BOTtoken, client);

to :

WiFiClientSecure test;
UniversalTelegramBot bot(BOTtoken, test);

and you can see my Serial monitor in both time:

Starting ...
Connecting to hooshmandsazan3

Hello, I need to process a message sent to the bot. how can i do this using ESP8266-TelegramBot?

If i try to use the Bot and to have some other fuctions like sending an Gmail, the ESP do a reset.
(a memory problem)
with
Serial.printf("Free heap size3:\t\t\t\t\t%d (bytes)\n", ESP.getFreeHeap());
we can look for the free Heap and if it's go low like 17152 there's the problem.

client.println("Connection: close"); /// zum speicher frei geben
return mess;

will remove the problem in my Sketch

Hello,

Can you add support to send e.g. a jpg image which is in the esp8266's ram to telegram?

Regards

[HTTPS] Received payload telegram:
Sent Update request messages up to : }

update-id and date always the same value
i am using the examples/EchoBot
bot keeps sending same message

I tried a lot things wrote in this Issue:
esp8266/Arduino#1426
(interrupt/timing problem)
My workaround;

ETS_GPIO_INTR_DISABLE(); // interrupt disablen wegen softuart, da sonst wdt reset möglich
IPAddress server(149,154,167,198);
....
client.println("Connection: close"); /// zum speicher frei geben
ETS_GPIO_INTR_ENABLE(); // interrupt enablen/disablen wegen softuart, da sonst wdt reset möglich

In my Telegram-bot Lib.
(Connection: close remove also a Bug if you try to send an Email an with Telegrambot usage)

With that workaround there is missing Serial Data. So i do this in my Sketch:

for (int l = 0; l < 20 ; l++)
               { 
                error = my_sds.read(&p25,&p10);
                  if (!error)   {
                                break; 
                                }
                    else       {
                                p25=-2;
                                p10=-2;
                                } 
                delay(100);
                }

hi , sorry to open ticket for my question but I really appreciated to have your advise. Actually I intend to make secure one to one communication between my ESP module and my phone (or couple of allowed phones), There is ESP8266WebServer, hosting web page, and intend to register allowed phones numbers by it, what is your suggestion to find id number of allowed phones and made secure communication
Thanks

Hi, I always get this when compiling the examples

What am I doing wrong?

hi my friends, i wanna use my own server client for Telegram bot with webhook method , but my request didn't deliver to the Arduino board not at all, can u help me?

Hello,
when using the Telegram command "/start" the string is not recognized in the example and the string "entities":[{"type":"bot_command","offset":0,"length":7}]}}]} is ignored in the function.
I can suppose this is an issue in the Telegram new bot api version.

Good evening, thank you for your library, it seems to be powerful.
I m using Arduino ide and NodeMCU v3 board, i installed ESP8266 v. 2.3.0 and update sketch EchoBot.
Of course i filled the requested fields like SSID and PASSWORD with my wireless credentials, but on Serial it writes:
Connecting Wifi: [mySSID]
................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
and never connect. with other libraries it does, but it crashes later on sketch for other issues. With your library, it doesnt connect so i cannot see if it works with my BOT.
Where am i wrong?
Thanks
PS i tried with another wifi, because i ve differents on my home, with different keys (wpa2, wpa, wep): none of these works.
Any help is apprieciated.

bot.sendMessage( m.id , "中文","");

telegram client show
\u4e2d\u6587

big5 to utf8 ?

Hi, in example flashedbot, 43, 47, 51 string. if (bot.message[i][5] == "/ledoff") { need to change to "ledoff", because we cut 1 symbol "/"

Hello
tell me how can I get the time to send a message (timestamp) from a variable date?

Thank you

E' previsto ? Non riesco piu' a ricevere risposta dal bot nonostante veda sul monitor seriale che il messaggio arriva.

Is not working

hi, thank you for the library..
i have a little problem here. when i try to send multi line text, but the only first line is sent.

any solution? thank you

Hi.
Excuse me for my English.
I’m using flashled bot and I’m trying to build a device that has high reliability.
Sometimes When I deliberately disconnect Internet connection ,my ESP’s hangs and after about 13 minutes it recover again and send failed to update to serial monitor.if I re-establish Internet connection between that 13 minutes and send a new command to BOT ,ESP can not run it and I will wait to that times be elapsed
But sometimes it doesn't hangs and after lower than 2 seconds I see failed to update in my serial monitor.
Is there any defined timeout for waiting for server reply?and how I can decrease it to lower than 1 minutes?
I hope I could explain what I mean.
Thank you in advance.

When I want complile Flashedledbot.ino I have this problem
How to solve it?

warning :

I did compile and upload successfully echo example and my ESP8266 connect to my network with no problems.
After that the MC start to rebooting continuously with error:

What can be a problem ?

Happy new year to all.
with current library each message closes the connection and makes a new one .
so I need to know is it possible to keep the connection alive permanently to process the new arrived message faster?

We had trouble connecting to wifi. Things worked only when we changed this

while (WiFi.begin(ssid, password) != WL_CONNECTED) {

to this

WiFi.begin(ssid);
while ( WiFi.status() != WL_CONNECTED) {

(Btw, we were using wifi without password)

Thanks for the code though, works great now!
(Btw2 This message comes straight from Thingscon Amsterdam, we just did the Telegram Arduino MKR1000 workshop with Davide, and wanted to find out if we could get it to run on the ESP's which were handed out for free at the conference)

why can't connect to server? many example trying

here is output when internal debug is active

Checking for messages.. GET Update Messages
[BOT]Connecting to server
[BOT]Conection error
Received empty string in response!
0 new messages

please any update? how about fingerprint api.telegram.org

Hi guys, I'm getting this "failed to update" error in my serial monitor as soon as the ESP is connected to my WiFi.

Does anyone know how to solve this? is this a code related problem or a TelegramBot related problem?

Thanks in advance!!!
