Glad to hear that it worked, thanks for the update.

Thanks, setting UART1_ENABLED in sdk_config solved the problem. Afterwards the code compiles without errors and I can use both UARTE0 and UARTE1 in parallel. I tested it by enabling using UARTE0 for NRF_LOG stuff (NRF_LOG_BACKEND_UART_ENABLED) and UARTE1 for my own serial communication.

Hello,

Please try to set UART1_ENABLED to 1 in your sdk_config.h file. Th
