Understanding MAC_ENUM_CHANNEL_ACCESS_FAILURE #45

Guys

I'm a little bit stuck with zigate v2, v3.21 network and MAC_ENUM_CHANNEL_ACCESS_FAILURE error.

There are attribute reportings from the device then MAC_ENUM_CHANNEL_ACCESS_FAILURE errors. What does it mean ? How to interpret that ? Thanks

Hi, MAC_ENUM_CHANNEL_ACCESS_FAILURE is referenced as CSMA/CA channel access failure What I understand is that CSMA/CA is a system that checks if the used channel is clear or not. Therefore, I think there is an access flood to the channel or perhaps to the cpu.
