About 802.15.0.4 wireless uart example problem

[jiabchen]

Hi Nordic team

I tested the example[802_15_4\wireless_uart\raw\first] period 1s send 20 Byte data to example[\802_15_4\wireless_uart\raw\second]serial tool to printf these data.

send/receive run nRF52840 demo board.

But now appeared a phemon:first and second demo board work well and serial tool printf data period 1s，But after servel minutes. serial tool has no any data printf.

I reset the demo board(raw/second),it also can receive data on the serial tool. 

Base on the above，I had no modify any Configuration.

What can I debug this problem?

And encountered another problem: I also run 2 demo board(run the raw/first),the third demo board(run the raw/second) can not printf 2 demo board data on serial tool.

I remember I had tested the orginal example,it can run on the serial tool, 2 board(run raw/first) can send data successfully to third board(run raw/second) show successfully on the serial tool，in spite of I should click manually by myself to send the data.

Thanks!

It seem that error this API(void mcps_data_ind(mcps_data_ind_t * p_ind))

when I debug,I had found it appeared these log   

<info> app: Assertion info: Number of lost frames: -18
<error> app: Assertion fault: !(next_counter_val == rx_counter) line: 94 file: E:\Beck\SDK\nRF5_SDK_15.3.0_59ac345-1\examples\802_15_4\wireless_uart\main.c
<error> app: ASSERTION FAILED at E:\Beck\SDK\nRF5_SDK_15.3.0_59ac345-1\examples\802_15_4\wireless_uart\main.c:94

run over 15min,it has encountered this phemon.

I capture 15min packet data,it lost 8 times. 

My test environment is inside, so why cause this lost frames?

Thanks!

Hello,

I did not manage to replicate the assertion by transferring a large file from one board to the other. The screenshot below shows how my test was set up. And I used the original example without security from SDK 17.0.0.  Could you try the same?

Hi Vidar Berg 

you mean that I test the SDK17 try to it?

Thanks!
