I think you have email Cytron support and show that it works originally, wireless communication is fine until you perform write firmware operation to XBee module.
Did the write operation success? We did see this symptom sometime, when you rewrite the configuration, the process fail and the firmware on XBee corrupted. And it cannot be recognized as XBee. Reloading firmware is essential to bring it back to normal. Try to use the following guides to reload firmware.
1) Connect USB cable to SKXBee and to computer
2) Lauch X-CTU and set the default setting - COMx(the biggest number COM), 9600bps, 8data bit, no parity and 1 stop bit
3) Go modem configuration tab, select XB24(for XBEE) or XBP24 (for XBEE-PRO)
4) Select XBEE 802.15.4 for function set and 10CD for version
5) Select always update firmware and and show default
6) Press and hold the RESET button on SKXBee
7) Click "write" on XCTU window
8) When action required box come out, release the RESET button
9) The box will disappear and start loading firmware
10) If fail, please try a few time.
It is recommend to change the setting using AT command, as writing firmware will take bunch of data and might cause the process to fail and lead to firmware corruption.
