Library compatible with SIM5320A? about sim7000-lte-shield

[ichai05023]

Hi botletics! My issue is fixed now by finding another hosting site. Again, thank you so much for your work!

[botletics]

It should be compatible, although I know HTTPS uses different commands. Did you first enable GPRS before posting? That's critical for the HTTP to work properly. You should also replace the Adafruit library with my version of the library. Follow the wiki in this Github and load the LTE_Demo code and use the "G" command to enable GPRS then use the "2" command to send data to dweet.io.

As a side note, I actually wrote a function for the SIM5320 HTTPS in my fork of the Adafruit FONA library in a different repo. The function is called "postData3G" in the .cpp file if you want to take a look.

Let me know if you get it working!

[botletics]

Sorry, actually now I recall that the SIM5320 doesn't use the same HTTP commands as the other modules. It uses the "AT+CHTTP____" commands instead. I would have to update my library to get it working.

[dahdo1m]

I have been trying to send AT+CHTTPS___ using the pass through tunnel, this is what I'm getting:

AT+CHTTPSSTART
OK
AT+CHTTPSOPSE="https://dweet.io/dweet/for/dahdo1m?temp=24.6",443

"no response"!

[dahdo1m]

I have been reading the SIM5320A AT Commands List, the HTTPS commands are quite different, and I feel that I don't fully understand what they are supposed to do.

[botletics]

I haven't tried pass through tunnel. I'll update my library shortly with an HTTP/HTTPS function for you to try shortly. Will keep you updated. However, I can't actually test it out since I don't have a SIM5320A anymore.

[botletics]

OK, I just updated the library and the "LTE_Demo" sketch. Just follow these steps:

• Delete the existing Adafruit FONA library you have in your libraries folder (path is Documents/Arduino/libraries by default)
• Follow this wiki to get my version of the library installed
• Open the "LTE_Demo" example sketch but uncomment the "SIMCOM_3G" line instead of the default "SIMCOM_LTE" line at the very top of the code
• Upload and run the code. You should see the menu appear.
• Enter the "G" command in your serial monitor to enable 3G
• Enter the "3" command to send data to dweet.io via HTTP or HTTPS. Check out the function definition in the sketch on how to use the function. By default it sends via HTTPS.

Let me know if it works! I'd love to know since I don't actually have one to test it out.
Thanks

[dahdo1m]

Hi Tim,

I tried it today, the code you wrote does send the following AT Command CHTTPSSTART and CHTTPSOPSE. The response for the first is OK, but the response for the second is ERROR, just similar to what I described earlier when I used the pass through tunnel. Are we using proper AT Commands? Do you think that SIM5320A is not suitable for connecting to the internet and sending data? The reason I'm asking is because the AT Commands list for SIM5320A does not show HTTP commands, and the HTTPS commands feel insufficient to send data through the 3G network.

[botletics]

The SIM5320A definitely works with HTTP and HTTPS, I tried it before. It just uses different commands than the other 2G modules.
Let me ask again:

• Did you first enable GPRS with the "G" command in the LTE_Demo sketch?
• Are you even connected to the network? Use "n" to check network registration

[dahdo1m]

I enabled it by pressing G, or by pressing g then G, the network was available, signal appeared to be OK, and network was registered.

[botletics]

Hmmmm that's strange. I'll investigate this when I get a chance.

[botletics]

By the way, did you set the right APN for your SIM card? By default I use "hologram" but you need to change it for your specific SIM card if you're not using a Hologram.io SIM card.

[dahdo1m]

I used the APN for AT&T "m2m.com.attz"

[dahdo1m]

I have an AT&T trial sim card

[botletics]

Please verify that it's sending the following AT command exactly as the line below:

AT+CHTTPSOPSE="www.dweet.io",443,2

[botletics]

If it is and it's failing, then go to the LTE_Demo sketch and search for this line:

if (!fona.postData3G("www.dweet.io", 443, "HTTPS", URL)) // Server, port, connection type, URL

and use good 'ole HTTP instead and see what happens:

if (!fona.postData3G("www.dweet.io", 80, "HTTP", URL)) // Server, port, connection type, URL

Also try getting rid of "www" and see if that works. I'm pretty darn sure this worked with "www" when I tested it on SIM5320A.

[dahdo1m]

Hi Timothy,

I tried doing this today I kept getting the response: ERROR, whenever it sends the "AT+CHTTPSOPSE" command

[botletics]

Could you please take a screenshot of the serial monitor output? Thanks!

[dahdo1m]

[dahdo1m]

I tried changing it to "HTTP" and 80,2 , and removing "www." also, all gave the same response

[botletics]

Looks like you have some weird characters showing up at the end of the "CHTTPSOPSE" command. That could very well be the problem. Does it do that every time?

[dahdo1m]

Only after I changed it

[botletics]

Doesn't look like you were entering the port 80 correctly. You should be copying/pasting this line instead:

if (!fona.postData3G("www.dweet.io", 80, "HTTP", URL)) // Server, port, connection type, URL

the "2" means HTTPS and is interpreted inside the function, so you shouldn't input that. In this case it will interpret the "HTTP" as "1" and not a "2". Try that and take another screenshot please! Also, keep the "www" because I'm sure that worked with mine before.

[dahdo1m]

[botletics]

Ahh OK, must be a library thing then. Will look into that.

[botletics]

OK, just uploaded a new Adafruit_FONA.cpp file in the repo. Download that and replace the existing one in your Arduino libraries folder (Documents -> Arduino -> libraries -> Adafruit_FONA by default), restart the IDE, and re-upload and see if that fixed the weird characters.

[dahdo1m]

It worked :)

[botletics]

Awesome! You were able to post data via HTTPS as well?

[almagroos]

Hi,
I need your help,
I am trying to sen data my web page using Adafruit 3G FONA SIM5320A

I got the same error. Please see the attached picture.

[botletics]

Sorry, currently I don't have a SIM5320A to test personally, but people say the library works with the same AT command sequence.

[almagroos]

Thank you for your replay.

I downloaded the folder "code" and I followed all the instructions that you posted in your page.
I am not sure if I used the right Adafruit_FONA.CPP because the code cannot recognize the fona.postdata3G function.

any suggestions my project has been suspended.

[botletics]

You might have an old version of the library. When did you download the code folder?

[almagroos]

yesterday.

[botletics]

Can you please copy the error message here? It compiles just fine for me.

[botletics]

And did you uncomment the line

#define SIMCOM_3G // SIM5320A/E

near the top of the code, and comment out all the other lines?

[almagroos]

I did that

[botletics]

Can you please copy the error message? You also need to delete any existing Adafruit FONA library inside your Arduino libraries folder (default for Windows is Documents/Arduino/libraries). Most likely you have redundancies and it's using the old library.

[almagroos]

I used this line instead of the other
if (!fona.postData3G("www.dweet.io", 80, "HTTP", URL)) // Server, port, connection type, URL

[botletics]

Please see my previous comment and delete any old Adafruit FONA libraries that you may have installed before installing mine.

[almagroos]

I did and I will do it again now

[almagroos]

I got the same error message

[botletics]

Also, if it doesn't even compile, how did you get it to run the code? You showed it running the LTE_Demo already...

[almagroos]

When I use if (!fona.postData("www.dweet.io", 80, "HTTP", URL)), it is working but the error as in message below

FONA> G

[almagroos]

it works when I use fona.postData() instead of fona.postData3G()

[botletics]

Please use the updated version of the examples as well, you have an old version. The new LTE_Demo does not have the "postData3G()" function.

https://github.com/botletics/SIM7000-LTE-Shield/blob/master/Code/examples/LTE_Demo/LTE_Demo.ino

[almagroos]

Should I change the port to 80 or not

[almagroos]

Same error

[botletics]

For the SIM5320 you need to use the "3" command, not "2". You can try port 80 and "HTTP" but I doubt that would make any difference. Sorry, I don't know what's going on with your setup.

[almagroos]

Do you mean this line
#define SIMCOM_3G // SIM5320A/E

[botletics]

In the post above you used the "2" command in the LTE_Demo. You should use "3" instead. But yes, you should also use the SIMCOM_3G define line.

[almagroos]

when I chose 3 in command I get this error

+STIN: 25
3

<--- ERROR

Please is there any error in this line of code

Serial.println(F("Failed to complete HTTP/HTTPS request..."));

[botletics]

You should include at least the host name, otherwise how does it know where to go?

HTTP/1.1\r\nHost: dweet.io\r\n\r\n

Sorry, Github is not the place to debug other people's code. If it doesn't work with the code I provide I will look into it, but once you change it I really don't have the time.

[rene6262]

Hi, ive been following your steps but no matter what .cpp or .h i use i get lots of compilation errors...
I am using ESP32 and Sim5320A, this is what i get when trying to compile from your files. My files work fine for HTTP posting but now i want to use HTTPS.

Thanks

[botletics]

Please use the .cpp and .h files in this repo as well as the example sketches and you shouldn't have any problems compiling for SIM5320 (3G).

[rene6262]

okay, there is compatibility issues with the ESP32 board, which i can change code for in the .cpp, however there is still the undefined commands i am getting. Is there a place to see what changes you made to the original fona.cpp file?

[botletics]

Oh, you're using ESP32? Sorry I haven't explored that much. I'm currently really busy but will try this when I get a chance.

[rene6262]

Im not sure if the issue is from ESP32 or not (ESP32 is only the microcontroller, HTTPS is from sim5320A), this is what i get in my output logs:

[botletics]

First of all, could you please provide your full code here so I can debug? If you compile for Arduino Uno, Mega, Leonardo, etc. it should work just fine.

[rene6262]

Sure, i am trying to use your LTE demo code, the only changes i made are software serial to hardware serial. Here is the changes ive done, the rest is your code:

#include <HardwareSerial.h>
HardwareSerial Serial2(2);
HardwareSerial *fonaSS = &Serial2;

while (!Serial);
// ss.begin(GPSBaud); // begin the GPS serial connection
Serial.begin(115200);
Serial.println(F("Initializing....(May take 3 seconds)"));
//fonaSerial->begin(115200);
Serial2.write("AT+CDIPR=115200"); // Set Baud to 115200
delay(500);
Serial2.begin(115200);
delay(500);
if (! fona.begin(*fonaSS)) {
Serial.println(F("Couldn't find FONA"));
pinMode(FONA_RST, OUTPUT); //set a pin mode on the FONA_RST
int attempt = 0; // a counter to check the number of times the fona has been reset
while (! fona.begin(*fonaSS) && attempt != 5) { //try to reset the FONA 5 times before giving up
Serial.print("Resetting FONA...Attempt");
Serial.println(++attempt);
digitalWrite(FONA_RST, LOW); //set the FONA_RST pin low (Reset the fona)
}
}
digitalWrite(FONA_RST , HIGH); //pull FONA_RST back to high

[rene6262]

and with the Uno i get this library error:

                           ^

[botletics]

If you are getting errors while compiling for Arduino Uno then it's something on your end (either package installations, libraries, etc.). Sorry, but I don't have time to dig deeper.

[botletics]

Using the LTE_Demo code I have on Github compiles with "ESP32 Dev Board" with the hardware serial change:

`// We default to using software serial. If you want to use hardware serial
// (because softserial isnt supported) comment out the following three lines
// and uncomment the HardwareSerial line
//#include <SoftwareSerial.h>
//SoftwareSerial fonaSS = SoftwareSerial(FONA_TX, FONA_RX);
//// Use the following line for ESP8266
////SoftwareSerial fonaSS = SoftwareSerial(FONA_TX, FONA_RX, false, 256); // TX, RX, inverted logic, buffer size
//
//SoftwareSerial *fonaSerial = &fonaSS;

// Hardware serial is also possible!
//HardwareSerial *fonaSerial = &Serial1;

// For ESP32 hardware serial use these lines instead
#include <HardwareSerial.h>
HardwareSerial fonaSS(1);`

[rene6262]

The issues im getting is calling the PostData command, it says const *char to char is -fpermissive or something in that manor.

[botletics]

But you said when you try compiling the LTE_Demo sketch for Arduino Uno without making any modifications, you get an error. That means something else is wrong.

[Snowfly-]

Hi...
Has there been significant changes on library regarding support on SIM5320 module.
Cause at this moment there comes compiling error 'class Adafruit_FONA_3G' has no member named 'setNetworkSettings'
Using LTE_DEMO example with correct changes to enable the SIM5320

[botletics]

It's still supported but a function name was changed from the default Adafruit function name.

[ELNAHUAL]

Hi Botletics,
I hope you can help me I'm desperate trying post data to MySQL database with no success.
I'm using an Arduino Mega with FONA 3G with SIM5320A chip and downloaded your library with examples.
I could succesfully post to dweet.io but now I need to modify the sketch to post to database that is password protected and cant find the solution.
I have modified "IoT _Example" using MQTT protocol changing server, serverport, user and key for the ones of MySQL database but had no luck, I'm having below data in serial monitor:

With a Wi-Fi device I can connect with server using below line:

but this doesn't work with FONA.

I would really appreciate your help.
Do you have any ideas?
Thank you in advance

[botletics]

Sorry I don't use MySQL. If you can set up MQTT on it or an HTTP endpoint then the library should work just fine.

[ELNAHUAL]

I've been chasing my tail on this, well I'll keep trying.
Thank you.

[fredericodamian]

Hello botletics! Sorry for reusing this issue and thank you very much for this library.
I'm using ESP32 + SIM5320E with LTE Demo code. The dweet post through command '3' is working well (unless by the second return from server which returns that it failed but it posted).

Thanks, I'll look into it when I get a chance.

[botletics]

So I looked at it and the "W" function was written by Adafruit and it doesn't support the SIM5320. I would recommend just using the "3" option to post data, and in the meantime I'll edit the LTE_Demo so that "W" doesn't show up as an option when SIM5320 is selected.

[ichai05023]

Hi botletics! First of all, thank you so much for providing this library. It helped me a lot.
Apologies coz I will ask for help this time.

I am reusing the option '3' on your LTE_Demo.ino which sends an HTTP GET request to a website.
However, the shield cannot successfully send the request. Kindly see results from Serial monitor below:

I am also trying to send the exact same GET request thru my browser and it works fine.

Regards!

[botletics]

First of all, does the dweet example work? And does the domain only accept HTTPS?

[ichai05023]

Hello, yes it worked on the dweet example. Seems like the shield is working fine and the fault is on the side of the web hosting. Btw, thank you for the response.

[RogerioTostes]

OK, acabou de carregar um novo arquivo Adafruit_FONA.cpp no ​​repositório.

[RogerioTostes]

Hello everyone I'm in need of help to run the post 3g example. I'm having the following error

I hope someone can help me, thanks.

[dahdo1m]

Hi botletics!

Do you happen to know a way to modify the code for SIM5320A to send data to things.ubidots.com?

I keep getting (Bad Request) or (Your Browser sent an Invalid Request) trying to upload data. Here's the dweet part of the code that I modified:

` case '3': {
// Post data to website via 3G or 4G LTE
float temperature = analogRead(A0)*1.23; // Change this to suit your needs

    // Voltage in mV, just for testing. Use the read battery function instead for real applications.
    uint16_t battLevel = 3700;

    // Create char buffers for the floating point numbers for sprintf
    // Make sure these buffers are long enough for your request URL
    char URL[500];
    char tempBuff[16];
    char battLevelBuff[16];
  
    // Format the floating point numbers as needed
    dtostrf(temperature, 1, 2, tempBuff); // float_val, min_width, digits_after_decimal, char_buffer
    dtostrf(battLevel, 1, 0, battLevelBuff);

    // Construct the appropriate URL's and body, depending on request type
    // Use IMEI as device ID for this example
    
    // GET request

Would you please help me adjust the code to post data to ubidots as well as dweet?

[botletics]

Hey, would you do me a favor and post that on the newly-created Botletics forum since it's less of a Github question? Thanks!

(Sorry, just trying to get more people on there lol)

Hi botlectics,

I'm using your sketch for sim5320E in Italy with Iliad network (apn: iliad) but everytime I'm trying to connect with HTTP it's saying "Failed to complete HTTP/HTTPS request...". I'm new with this and I tried to shred your program as per my requirement. Can you check and let me know where the trouble is? Thank you

The issue is that you are not enabling data. Try the "enableGPRS(true)" command before doing the actual HTTP request.

[Barnik12]

I tried your original one, the problem remains. On "AT+CHTTPACT=?" its showing: Ringing/in progress (outgoing).
And on command 3 its showing:
--> AT+CHTTPSSTART
<--- ERROR
Failed to complete HTTP/HTTPS request...

Can you give me a simplified program for https because I want to use it with blynk. Thank you

[botletics]

Maybe you're connected to a call somehow? Maybe hang up first. Use the LTE_Demo.ino sketch but with #define SIMCOM_3G uncommented and comment out the default #define SIMCOM_7000 and then use command "G" and then command "3" to post data. Sorry, I'm not in the position to make customized code for people.

[Barnik12]

So I did like this:

#include "Adafruit_FONA.h"

// Define *one* of the following lines:
//#define SIMCOM_2G // SIM800/808/900/908, etc.
#define SIMCOM_3G // SIM5320A/E
//#define SIMCOM_7000 // SIM7000A/C/E/G
//#define SIMCOM_7500 // SIM7500A/E

// For TinySine SIM5320 shield
#define FONA_PWRKEY 8
#define FONA_RST 9
#define FONA_TX 2 // Microcontroller RX (note: won't work on Mega)
#define FONA_RX 3 // Microcontroller TX

// ESP8266 + SIM7000 shield
//#define FONA_PWRKEY 14 // D5 on NodeMCU
//#define FONA_RST 12 // D6 on NodeMCU
//#define FONA_TX 4 // D2 on NodeMCU, microcontroller RX
//#define FONA_RX 5 // D1 on NodeMCU, microcontroller TX

// For SIM7000 shield
//#define FONA_PWRKEY 6
//#define FONA_RST 7
//#define FONA_DTR 8 // Connect with solder jumper
//#define FONA_RI 9 // Need to enable via AT commands
//#define FONA_TX 10 // Microcontroller RX
//#define FONA_RX 11 // Microcontroller TX
//#define T_ALERT 12 // Connect with solder jumper

and changed "fona.setNetworkSettings(F("iliad"))", then I'm getting the following:

FONA> G
---> AT+CGATT=1
<--- OK
---> AT+CGSOCKCONT=1,"IP","iliad"
<--- OK
---> AT+CIPMODE=1
<--- ERROR

FONA> 3
---> AT+CHTTPSSTART
<--- ERROR

FONA>

[botletics]

Try to hang up with "h" and then do "g" then "G" then "3".

[Barnik12]

This is how it's coming. What could be the problem?

[botletics]

Not sure why it's saying it failed, but that's on the library side. As you can see from the server response, it posted successfully.

[Barnik12]

So should I reinstall everything?

[botletics]

No, it's doing what it should be doing correctly. The only reason it's saying "Failed to complete HTTP/HTTPS request..." is because in the library file it's checking for a "+CHTTPSSTOP: 0" response when it sends "AT+CHTTPSSTOP" but it didn't get that response. It might be the firmware you're running or something, I'm not sure. What you could easily do is go into the library file and instead of lines 1929-1930 just write getReply(F("AT+CHTTPSSTOP"));

[Barnik12]

I'll now do what you suggested but 5 minutes ago I got this. What does "+CHTTPSNOTIFY: PEER CLOSED" means?

Not sure why you're getting that. Looks like this time it didn't work.
