battery voltage level nRF9160

[Lorenzo Amicucci]

Hi 

in nRF9160, there are several AT commands to measure/handle battery voltage: examples:

%XVBAT

%XVBATLVL

 Which PIN do they sense? are they VDD1 & VDD2 (which I believe are connected both to same Voltage input - e.g. from same battery)? or a dedicated PIN needs to be assigned for sensing VBAT? 

Many thanks

It reads the VDD voltage and VDD1 and VDD2 should be connected together.

There is no need for any external circuitry to read the battery voltage. I tested here now and it follows the VDD voltage without any prior configuration.
