Hi to all,
I have tested for a month the module I use, it is LILYGO TTGO T-Call ESP32.
I have last Micropython firmware. Last before this module works same...
I use it on USB power and it works great, CALLS, SMS Messages, incomming, outgoing... I put temperature sonde and it calls me when temp goes under or over min and max temperature, great... I have Battery too, and this is problem, when it starts and works on USB everithing is ok but when I disconnect USB adapter (5V 2A) from wall socket 220 V, it goes won with Battery power. Diode on the pin signals me that it works, code works. After connect it on USB again, it works as microcontroller but SIM module dont work anymore, it freezes the CALLS and SMSing but I know it works while my diodes constantly goes ON and OFF as I coded it. Then I disconnect power USB and BAttery and start it from USB again and then when he itialize, he send me those SMS that he has to send me when it was on Battery.
This module do not work on battery as espected, did someone have the same problems?
