There is no other way to preventing the errors than to stay clear of the conditions, mentioned in section 6.33.10.4 of the PS, that cause the errors. You should not make any changes to the source code. This thread describes how to clear errors and restarting the UART driver.

Hi Simonr,

We get above values when NRF_UARTE_EVENT_ERROR event occurs.

On the other hand, can we avoid getting NRF_UARTE_EVENT_ERROR event?

Eventhough, the data is rubbish data, we want to get and manage it inside our function.

We don't want to get NRF_UARTE_EVENT_ERROR at all time. Is it possible by modifying SDKs source code?

Please share us your comment

Thank you

This case explains how to reinitialize your UARTE. Are you able to identify what NRF_UARTE_EVENT_ERROR you are getting?

Best regards,

Simon

Hi Simonr,

We can use TWO UARTEs by setting nrf_serial_read() timeout to 0.

However, at some point we receive NRF_UARTE_EVENT_ERROR and can't resotre UARTEs until reboot.

Please share us how can we re-init or restore URATEs .

Thank you

Have a look at this post, as there is a modified main.c file there that may help you, as well as a long discussion on using 2 UARTEs. If you don't find any help there you can try simply setting the timeout in nrf_serial_read() to 0 as described in this post.

Best regards,
Simon
