Hi again

Yes, you would need to enable the UARTE1 in sdk_config.h and make a second (distinct) uart_init() function for the other UART instance where you need to make sure that it doesn't have any calls that will mix it up with the first uart_init().

Best regards,

Simon

Thanks for getting back to me Simonr, okay, would I just make another instance of uart_init(void) and the uart handler functions? And enable UARTE1 in the sdk_config.h?

Is there a reason you're using the SDK v12.3? This SDK only provides experimental support for the nRF52840, and production ready support is not provided until SDK v15.0.0. I would suggest using the latest SDK version(v17.0.2).

Either way, we don't have any examples as far as I know that implements both UART peripherals, but it should not be too hard to implement, just keep in mind to not mix UARTE0 and UARTE1 in your application.

Best regards,

Simon
