nrfx_uarte tx_rx_non_blocking not work (nRF5340)

[Marika Di Martino]

I'm just trying this sample: nrfx_uarte tx_rx_non_blocking, but this is what I can see in the terminal. Why those errors?

Hello Maria, thank you very much.

Hello,

I hope the workaround is working for you, because the sample not be updated. The reason for this is that we recommend using Zephyr APIs and not nrfx directly. You can read about the available Zephyr APIs for UART here.

Just to be clear: The nrfx drivers will be updated when needed, but the examples will not.

Best regards,

MAria

Hello, I moved the nrfx_uarte_ininit function at the end of the main and it works. Thank you for your clarification. Marika
