i have a problem with xb24-zwit modules with 23A7 firmware.
I use a atmega328 rx tx connected to tx rx of xbee. After start-up, some times, the rx pin of xbee don’t work but the tx pin work fine. If i send AT command to radio, the radio don’t execute command (for example FR reset) but if the radio receive data from the coordinator, the tx pin work fine and send data to processor. Also the pin assoc work correctly reporting the status of association.
I tried to reset the processor but the radio still does not respond to commands. The radio receives correctly only after a hardware reset or restart supply.
Thanks for the support
