[nRF SDK]Disabling nRF Async UART at run time

[Sachin]

Hi,

 The nRF UART running over the ASYNC interface consumes a lot of current even when not in use. As ours is a battery-operated device we intended to disable UART when not in use.

And enable dynamically as required. Please suggest a way to get this done.

Thanks

Hi,

You can use the APIs uart_rx_disable() and uart_rx_enable() to dynamically stop and start the async UART during runtime. The TX should generally not be an issue, as it will stop once the transfer is done, but there is also a uart_tx_abort() API that can be used for stopping transfers.

Best regards,
Jørgen
