What are you working with?

Modem: LilyGO SIM7000G Main processor board: ESP32 / LilyGO SIM7000G TinyGSM version: latest from ArduinoIDE Code:

Scenario, steps to reproduce

Call modem.restart() to initialise/restart the modem

Expected result

At some point modem.restart() should return with true/1

Actual result

modem.restart() never returns with true. When one ignores the return code and continues with the initialisation, all seems to work, the following steps do not return any follow-up errors. Same can be seen in official example-code from LilyGO vendor: https://github.com/Xinyuan-LilyGO/LilyGO-T-SIM7000G/blob/master/examples/Arduino_TinyGSM/AllFunctions/AllFunctions.ino

The "return" is disabled, the return code of the reset()-function is ignored
