XIAO_BLE_Sense(mbed 2.7.2) battery charge and voltage monitor, analogRead(P0_31) does not work

Hi PJ,
Thanks for trying.
I have tried with your sketch. I am able to measure the battery voltage without any problem. I don’t know why it differs from your numbers. But the variants files seems to be working fine.
Thanks.
