Hi I just tried your latest update. It compiles fine now! just getting a watchdog reset. This is a thing related to the wifi capabilities of the ESP. If you do not call yield() or delay() for 3 (?) seconds the ESP will reset. This is from the HTTPS_GET test sketch, adding delay or yield in a loop should be an easy fix.

Hi @Bartvelp, The delay() functions are used quite often in the driver to manage the delays for establish GPRS communication and so on. I made some experiment with the avr/wdt.h library (watchdog management for AVR) but it doesn't recognise the yield()command or consider the usage of delay()as yielding. After reading the code again, there is no active waiting. The delay() calls are used properly. Did you try to only remove the while(!Serial); in the beginning of the examples? It should be enough. KR, Olivier

KR, Olivier i use esp 32 and sim 800l to sends the HTTPS POST request to clould function.i remove while(!Serial):but no use.its automatically resets and shows this type of error.

please help me to find out the solution

As mentioned in the README, the project is no longer maintained as my module is broken. Thanks for reporting the issue.
