SO reference: arduino - Thinger.IO client setup for GPRS enabled ESP32 project - Stack Overflow
Hi,
I’m curious, why dont you use the GSM Thinger example? I’ve tested it and works like a charm with the ESP32, even with the OTA.
Where is that example? Here is my full code which works fine - it connects to the APN, downloads some content from the internet but it doesn’t get connected to thinger - the status there stays “Disconnected”
Unfortunately, this forum has a lot of restrictions related to posting a new question. That’s why I moved my question to stack overflow. You can see there my complete code.

Hi
The Arduino GSM example, I prefer to use the hardware serial ports on the ESP32, the final sketch should look like this
// Select your modem:
#define TINY_GSM_MODEM_SIM800
//#define TINY_GSM_MODEM_SIM900
//#define TINY_GSM_MODEM_A6
//#define TINY_GSM_MODEM_A7
//#define TINY_GSM_MODEM_M590
// uncomment line for debug
// #define _DEBUG_
#define RX2 16
#define TX2 17
// Can be installed from Library Manager or https://github.com/vshymanskyy/TinyGSM
#include <TinyGsmClient.h>
#include <ThingerTinyGSM.h>
// Emulate Serial1 on pins 10/11 if HW is not present (use interrupt pin in RX for better performance)
//#ifndef HAVE_HWSERIAL1

//#endif

#define LED_BUILTIN 13
void setup() {
// uncomment line for debug

// more details at http://docs.thinger.io/arduino/
}
void loop() {
thing.handle();
}```
Of course maybe you need to change the RX2 and TX2 pins.
Try it and let us know how it goes.
Hope this helps.I tried your code but it doesn’t even connect to the internet. As I said, the code that I’ve posted above works - it CONNECTS to the internet but it DOES NOT CONNECT to Thinger’s cloud platform where my device is added (It has device id and password). So, I assume the issue is with the client libraries that I used for Thinger.
The board that I use is called ttgo t-call esp32 sim800l It is not only sim800. It is a bit more complex.
UPDATE: IT STARTED TO WORK!!! THIS IS THE CODE:

Please, let me know if it can be further optimized? I want to simplify it as much as possible. I will not use the module for SMS, CALL etc. I need it only for the GPRS.

I am getting this error, when I am trying to use http.client(server) with ttgo-t module, Could you help me out.
Hi,
Some command is causing the uC hangs, check carefully your code.
Hope this helps.
