Peripheral UART example - Might I use UART_1 for send out data received via BLE?

[PingISTL]

Dear Support

Try to modify this use UART_1 for sending out data received via BLE, which is pin P0.14 on nrf52833dk_nrf52833, I modified Kconfig file under the boards folder

config BT_NUS_UART_DEV

default "UART_1"  

It compiles ok, discovered by my phone,  but when i send message form BLE side,  I cannot probe the data on TX line with logical Analyser, while I see it when use default UART_0 on pin P0.06. 

Anything else I need to do in order to let it work on UART_1? My target board use other pins for UART interface, and I understand any pin can be configured to be UART pins.

Thanks you for your attention.

Hi,

You need to add an overlay file which enables and sets up uart1, and also disables i2c1. Here's an example, that you can modify for your desired pins:

&uart1 {
    status = "okay";
    tx-pin = <  >;
    rx-pin = <  >;
    label = "UART_1";
};

&i2c1 {
    status = "disabled";
};

If it still does not work, please tell me the pins you are using and any other information that may be useful.
If you are using SES, remember to run Project->Run CMake after changes to Kconfig, prj.conf, and overlay files.
