Hi, I am using nrf52832 dev-kit. I use P0.23 or P0.24 as an input pin. I am trying use this pin to read data from other device. When I use this pin like button, it can detect high or low states. But when I connect it to other device for communication it can not detect changes. I used stm32f4 board to check if other device is broken but stm could handle the data and it gave me correct data. My nrf52832 is always giving me 0. How can I fix that?
