Hi Jonathan,

Finally, I found that I did not clear the memory through nrf_libuarte_async_rx_free(), which caused the Buffer to be full.
Here I would like to ask another question where the size of Rx Buffer can be set

Hi Kai,

Could you also create a new ticket, then include more info, maybe parts of your code also? And then reference this ticket.

ERROR 0 = no error, prosess was a success.

Hi All,

I have roughly the same question,i'm using SDK v17.1.0.

According to the picture,I can receive data, but the same error will appear after some time

Best regards,

Hi sorry for the late reply,

I dont have a propper solution for now.

Is there any reason that you use sdk17 and not 17.0.2. SKD 17 is not supported anymore and dos due to som bugs. i would recommend to change to 17.0.2 or is there a reason you are sticking to an older version?

Jonathan

I don't believe both are being used, I copied the code over from the libuarte example itself.
From libuarte example, line 60:

NRF_LIBUARTE_ASYNC_DEFINE(libuarte, 0, 0, 0, NRF_LIBUARTE_PERIPHERAL_NOT_USED, 255, 3);

From ble_app_uart modified accordingly, line 70:

NRF_LIBUARTE_ASYNC_DEFINE(libuarte, 0, 0, 0, NRF_LIBUARTE_PERIPHERAL_NOT_USED, 32, 3);

The 4th and 5th parameters are for passing the timer and rtc IDs respectively, and it appears as rtc is not being used according to the "NRF_LIBUARTE_PERIPHERAL_NOT_USED" parameter.

I don't see how the issue could be within main.c if I copied the relevant code from the libuarte example itself, the libuarte example works just fine. I was expecting something to do with sdk_config.

Hi

in the NRF_LIBUARTE_ASYNC_DEFIN function you have to choose RTC or TIMER cant use both.

Hi,

Are you sure you added the correct zipped file of you project. i cant find any references to libuarte in main.c
