Does BLE UART affect hardware UART

[NewNate920]

I'm trying to send data from a NUCLEO F401RE board with the nRF 52840 DK using UART. Then have the data to be sent to my phone via Bluetooth. I'm starting from the ble_app_uart example. Is it possible to use UART to both send data from the MCU to the nRF 52840 DK and send data to my phone? or will I need to find another way to connect my MCU and nRF

Sure!

The ble_app_uart example simply forwards everything received on the nRF hardware UART to the BLE Service,  and everything received on the BLE Service to the nRF hardware UART
