Yes, the nRF52832 support even parity (odd parity is not supported).

Thanks. I have checked it. The value of app_uart_evt_t.data.error_communication is 0x2 (parity error). Does nRF52832 support even parity for UART?

Please check the error source in app_uart_evt_t.data.error_communication when receiving APP_UART_COMMUNICATION_ERROR event, and compare this to the explanation of the ERRORSRC register.

In the case of first issue, I have found the cause. I did not put LF at the end of sending data from terminal emulator other than "Termite". So the event APP_UART_DATA_READY occurred, but data was not relayed via BLE.

In the case of second issue, the event APP_UART_COMMUNICATION_ERROR was occurred in uart_error_handle(). nrf_drv_uart.c detected NRF_UARTE_EVENT_ERROR in uarte_irq_handler.

Have you tried debugging, to check for any error codes from your function calls?
