I am having problems with my zigbee modules (coordinator and end device). Every first time, I power up my modules, they can pair, but they can not communicate. Whenever that happens, i can see that 0xA1 is being received by my COO and 0xA3 is being received by END device.
A couple of attempts before successful communication.
Successful communication does not show the frame types I mentioned above.
Is there something I should turn off or set or reset?
