XIAO BLE Sense battery level and charging status

[mithundotdas]

Thanks. I guess I need a little more help. I set P0_14 to OUTPUT and trying to read P0_31 but getting value of -1 always.

code snippet

void setup(){
pinMode(P0_14, OUTPUT);
pinMode(P0_31, INPUT);
}

void loop(){
   float batV = analogRead(P0_31);  //this reads to -1
}
