ERROR 0 [NRF_SUCCESS] occurs after Rx receives a fixed amount

[kai19960504]

Hi All,

SDK => v17.1.0

IDE  => segger

I have a question,according to the picture,I can receive data, but the  error will appear after some time.

Why does the function return an error when it returns successfully?

My data is fixed in the range 0x2000606c to 0x2000626a

Best regards,

Kai

Hi,

Do you call nrf_libuarte_async_rx_free() in the UART callback handler?

Hi Jared,

No. I don't. I added nrf_libuarte_async_rx_free() at the end to solve my problem.

Best regards,

Kai
