Hello blh64,
The strings have almost always been in the F() function and therefore in the PROGMEM. In the meantime I have simply commented out all Serial.print commands. Since then the program runs stable. For programming work I can activate the serial output at any time again.
In principle you could split the C-String into several small parts, but I use a standardized function for the communication with the Sim800L, which waits for the Sim800L to confirm the command, e.g. with 'OK' etc.
My problem is rather that I can not yet transfer the data encrypted with SSL. As soon as I change the URL index on https:// the transmission does not work anymore. Also the AT+HTTPSSL did not help.
Maybe I should really make a POST instead of a GET. That could possibly help...
