Vbatt and Vcc are both connected to a power supply that provides 3.3v.
Vcc_io is always connected to 3.3v (the same as the MCU) with a 22R resistor
RST, wakeup, 1PPS, TX and RX are connected to the MCU, however, the module does not send 11s pulses on 1PPS and it consumes 5.6 mA all the time.
RF_IN is connected to an active antenna and a LC circuit to provide the 3.3v.
I am really confused, No wrong connection have been made, is it possible that the module needs to be flashed ??
