RE: Async UART and shell module in Zephyr on nRF52480

Hi,

[quote user=""]Now I need to add async UART to send some data outside the shell[/quote]

Could you check out this detailed sample using asynchronous UART in our nRF Connect SDK course to see if you have missed anything in the setup of the asynchronous UART? uart_callback_set() should only return ENOSYS if async api is not supported by the device, but this should be supported by the nRF52840, leading me to think there is something missing in your setup.

[quote user=""]Is there a way to use UART async API with the shell?[/quote]

Regarding this, I will ask around and come back with more details before Wednesday (within 2 working days). In the meanwhile, you may investigate this open ticket with a somewhat similar issue to see if you are able to spot your issue through their fix.

Let me know if these guides help you before I am able to reach back to you with additional information.

Kind regards,
Andreas
