T-Beam v1.2 GPS not working

[Sailorspoon]

SOC ESP32

Lora IC LILYGO LORA32 868/915MHz

Description

I am trying to figure out why the GPS module is not working.

I already tested the GPS reset and test firmware and the NMEA reset.

According to the data send to the serial monitor the GPS module can not be found.

Is this related to the AXP2101 chip of the 1.2 version or is this a hardware issue?

Here are the serial messages appearing when testing the different fixes:

Are you using the M10Q version? It seems that communication is indeed impossible. Contact the dealer for replacement.

[Sailorspoon]

If you are refering to the GPS module, I don't think it is the M10Q version. It says ublox NEO-6M-0-001 on the module. I will contact the dealer for replacement.
