ZigBee_OnOff example project: "RF IF return CCA or CSMA issue!"

[MTiao.1]

I am currently using 2 STM32WB55RG MCUs and they are currently running the ZigBee_OnOff example project. Unfortunately, they are not working due to this error message that I see on a HyperTerminal:

"RF IF return CCA or CSMA issue!".

I'm not sure what is wrong and I have not edited the example project code. I have flashed the appropriate firmware to the MCUs as well.

Hello,

Are you running your application in a very noisy environment ?

Eventually, you may try using another channel for instance number 15,20 or 25. By default, the OnOff Application is using channel 13, but you can try to change this value. To do so, you need to open app_zigbee.c file and change the value of the define named CHANNEL : (#define CHANNEL xx)

Of course, you need to do the update on both projects : On the Zigbee_OnOff_Server_Coord project and Zigbee_OnOff_Client_Router project.

Best Regards
