CC2650: [CC2650][ZStack] How to check the CCA threshold is triggered?

Hi Alan,

The capabilities of the CC2650 Zigbee solution are very limited due to the split stack and limited memory of the device.  I would recommend that you use the SimpleLink CC13X2/26X2 devices to further evaluate TI's Z-Stack solutions.  https://e2e.ti.com/support/wireless-connectivity/zigbee-and-thread/f/158/t/835289/

Hi Ryan,

Thanks for your suggestions. However, we have designed in our projects with CC2650 ZStack platform.

Currently, we just wanna know how to check whether the CCA threshold is triggered or not in this platform.

And, how to transfer the data which located in MAC layer to Application Layer?  

Thanks!

Hi Alan,

This is not functionality provided by default, therefore in order to achieve this you would have to modify the ZMac/zmac_cb.c from the ZStackCore project to pass along a failed MAC_MLME_COMM_STATUS_IND case (like ZMAC_CHANNEL_ACCESS_FAILURE) as a zstackmsg using ICall.  You can refer to the API folder of ZStackCore, ZStack folder of the application project, and the API Guide (starting from index.html) inside zstack_home_1_02_02a_44539/Documents/API/zstack_tirtos_api/ for more information.

Hi Ryan,

It seems hard to touch the goal. I don't know how to get the event (MAC_MLME_COMM_STATUS_IND ) from application task.

Is there any way to do that?

Hi Alan.Lin,

I have not tried this out for myself.  Have you evaluated defining MT_MAC_FUNC and MT_MAC_CB_FUNC as well as including the necessary files to a ZNP project?
