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

I suspected that, but thanks for extra look.
GL :slight_smile:
I went back and soldered the battery to the tester and loaded the BLE code fromb4 and Battery_Service is reporting same level as usb when plugged in Works perfectly in case anyone wants to see. and btw the battery is at 39% LOL :-p
