BLE Nano 2: Using reset pin as GPIO (Ardiuno IDE)


Hello! I need to use pin D10 (P0_21) as GPIO. The datasheet ( says it can be used as both reset and GPIO. However, I am unable to configure it as GPIO.

I tried using internal pullups in my arduino code:
pinMode(10, INPUT_PULLUP);
But this didn’t change anything.

Any help is appreciated, thanks!!


Hi alexshold,
We don’t provide the way to configure that pin as normal GPIO in Arduino and it is not advisable to change that reset pin. if you really want I think you can work using nordic SDK.


Ohhhh ok, that saves me a lot of time. Thanks Lucian!
