T-BEAM 1.2 does not work GPS NEO-6M with AXP2101

[rbarbosas]

I am implementing my own code to retrieve the GPS location but it is never updated,

I'm using a T-BEAM 1.2 which has a NEO-6M GPS module with AXP2101 chip, when I install meshtastic it can receive the location.

The AXP chip voltage configuration follows:

->  getSysPowerDownVoltage:2600
DCDC=======================================================================
DC1  : +   Voltage:3300 mV 
DC2  : +   Voltage:500 mV 
DC3  : +   Voltage:500 mV

DC5  : +   Voltage:3300 mV

Do you mean that writing meshtastic firmware can get the location, but the firmware you modified yourself cannot get it?

Have you tried this firmware?
