I have the following hardware:-
- 02 arduino uno
- 02 xbee pro s2b
- 02 xbee shields
- 02 zigbee usb module
I used ftdi as well as digi usb serial port drivers for identification of the zigbee usb module. both drivers independently identified the same as COM 23.
I further used putty and x-ctu for configuring the xbees. in putty after typing '+++' i do not get 'OK' as a response and in x-ctu test signal gives msg 'unable to communicate'. i have also tried all possible baud rate settings in x-ctu but the same msg comes.
I also tried communicating through xbee shield. i ensured that the jumpers were set on usb and the arduino reset was grounded. the msg is still the same
These xbees were configured 6 months back and it worked successfully. they were not used after that.
Presently when i connect the xbee to the arduino transmitter, the transmit led blinks on transmission of data but the receiver does not.
Also the transmitter and receiver asso leds blink at different frequencies when connected to respective arduino boards
Find attached error msg
Request guide me to sort out the prb.
Thanks in advance

A common thing with the XBee is to 'brick' them, especially if you don't have the pram Telem_Delay set to 3 or more.
If you search for fixing a bricked XBee you will find the formula.
It just involves using x-ctu and forcing a reload of the firmware.
I use XBee quite a bit and as long as I remember to set that delay I have no problems.
Thanks. Ive followed the instr on digi website for fixing a bricked xbee. however it didnt work. I didnt come across any delay setting in the instr. Cud u tell which version of xctu shud I use. Also u removed the xbee from the usb module and shorted tx and rx pins. However what is sent is not received...cud it be a driver prb for usb module?
Thanks @Mike if further i get any problem let U know mike !
