Hi everyone , please after a long discussion with DIGI about the problem i have with my xbee's serie 1 802.15.5 version 10EC, they answered e as above:
In order to perform a firmware upgrade, you need to have VCC, GND, DI, DO, RTS and DTR connected. I believe the Arduino Shields do not connect these lines from the PC to the XBee module. However you will want to verify that with the manufacture of the board in question. I think you will find that most 3rd party board will generally only connect Data in and Data out in addition to VCC and GND.
So anyone could help me with that o.O I didn't understand wthat should i do ?
