Hi, I have some question about wiredUART and USB to UART
I'm using nrf51822+BLE400.
Is there any difference UART communication between using USB to UART
and wiring on the UART pins?
I'm using ble_app_uart(SDK 12).
I'm asking because USB to UART port works fine but directly wired UART is not working.
It didn't receive datas from UART.
Should I use only one way for UART communication?
Should I change code to receive data from directly connected UART?
Thanks.
