Radio_Test on nrf52810 with custom UART Pins

[Iskailko]

Hello,

I need to use the Radio_test example on a custom board using the nrf52810. I am using the nrf connect SDK 2.5.1 with VSCode. 

To use the Radio_Test example I need to change my uart pins on my custom boards. Building the Sample for an nrf52dk_nrf52810 and running it on the nrf52dk works fine. However I cannot adjust the UART (Build works fine but the UART is no longer working). Therefore, I also do not know if the sample code runs on my custom board. 

I read that the Radio_Test example is not made for an nrf52810. How can I adjust it so I can use the nrf connect SDK 2.5.1 Radio_Test Sample with changed UART Pins on a nrf52810?

Hi,

Use dts overlay file to configure UART pins according to your custom board.

Yes this is the solution. 

On your custom board, do you use external LF crystal or the internal one? If the later you need to enable it in the Kconfig with

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y

CONFIG_CLOCK_CONTROL_NRF_K32SRC_500PPM=y

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC_CALIBRATION=y
