My xbee is not communicating and RED LED is on solid ON state? Please help me on my problem.

Which XBee module is this? What firmware version are you using? What steps have you taken to try and resolve this?

Hi thanks for reply. Xbee module is XB24C (Zigbee Reg) and FW version is 405E. I already set to “default” the xbee and then set to communicate to Coordinator but still no communication. I already reprogam the xbee still no communication.
