Scenario, steps to reproduce

Power on board with just compiled code.

Expected result

I expect a connection to an internet server and data send. Some times it work. I can't understand why sometimes works and several times it doesn't work. I try with different power supply methods but nothing change. Change antenna without any result. It lalways resets when try to connect to internet and exit with Guru Meditation. Sometime it reboots automatically for 2 or 3 times then stop. Other times it freezes and not reset.

Actual result

First boot

Is this also happening with the TTGO T-Call demo sketch on https://github.com/Xinyuan-LilyGO/LilyGo-T-Call-SIM800/tree/master/examples/Arduino_TinyGSM ?

The T-Call has a power management chip on board see https://github.com/Xinyuan-LilyGO/LilyGo-T-Call-SIM800/blob/master/examples/Arduino_TinyGSM/utilities.h sections for AXP192 or IP5306 -- there are tow different versions of the T-Call with this different chips. So you have to use the T-Call exampe sketch or implement the right power management (that drives the SIM800 also) in your code version!

Thank you for your quick end precious answer. Now I have done some test with the TTGO T-Call demo sketch and it works correctly, so i think there is a problem in my software. Now I'll compare my sketch with the example one and I'll find the bug. I'll keep you informed.
