Looks good to me except for your battery voltage. You should consider charging your device For the GPS I would refer to this issue https://github.com/bitconnector/ttn_mapper_t-beam/issues/23#issuecomment-1817932574

and now it seems to be working so I'll close this issue I think it was a bad antenna on the board
