Hello, I have a nrf51822 chip using s110 SD. I am trying to read a serie of 14 bytes from UART. If the device is connected to a phone with BLE I receive the correct values every time but if the device isn't connected the values is corrupted. The program also uses the same pin as an ADC input in another senario. What I have tried so far: I have tried to remove the ADC code to ensure that the two events wouldn't occur at the same time. I have also tried removing the BLE code. Unfortunately I can't post the code here due to confidentiality. Does anyone have a clue what the problem could be? Could it be in the library for connecting to BLE perhaps?

UART reading not working when the device isn't connect to a BLE unit

Hello,

Hi frans

When you remove the ADC configuration, is the result the same? Does the UART work prior to initialising the softdevice? Is the chip entering System Off by any chance after you disconnect?
