Looking for an example of implementing 2 UART connections at the same time for SDK12.3

[Robert Haddad]

Hi I have a custom nRF52840 board, and I have a current BLE UART setup. I also want to communicate with a IMU module via serial connection. Can you point me in the direction of a good example to start off from?

Thank you,

Robert

Hi

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

PS: The Holiday season is upon us, which will leave the Nordic support team understaffed until January 4th, 2021. This means that delayed replies will occur during this time. Sorry about the inconvenience and happy Holidays!

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?
