CC2538: TI MAC 1.5.2 Unknown callback event id

Pablo Devanne79

Part Number: CC2538

Hi,

We are developing a custom 802.15.4 coordinator based on the CC2538 and the TI MAC Stack 1.5.2. When executing some tests we sometimes have weird event id passed to the MAC_CbackEvent function.

I saw today that the event id passed to this function (value of pData->hdr.event ) was 0x61 which appears to be undefined to me. This appeared when devices had already joined the network.

Do anyone had this behavior before ?

Is there any processing we should do when receiving this kind of event (such a de-allocation of the buffer) ?

Thanks

Pablo

    Hey Pablo,

    I have not seen this behavior. Can you kindly give steps to reproduce and behavior vs. expected behavior?

    Hey Brocklobsta,

    I saw this happening when we try to stress our prototype by asking it to perform lots of data transfers to end devices. We implemented automated tests at system level and this is the way we see this issue happening.

    Also, I think during this tests the quality of the communication is not the best we could expect (because I can see re-transmit requests generated by our software controlling the coordinator).
