I inserted an XBee 1mW chip antenna into an XBee breakout board and connected it to a laptop via an FT232RL board. Using X-CTU the XBee could not be detected. I have tried various things, but without any success. I have detailed below the steps I have taken, and the responses I get.
1) The module is in AT command mode, I get “unable to communicate with modem”. This happens for all baud rates including 9600.
2) When the API box is checked and Test/Query button in X-CTU is pressed, the following message comes up:
Communication with modem OK…
Modem type: Name unknown (ID=42949672481977066586)
Modem firmware version:
3) Following on from step (2) with API box still checked, I clicked on the Modem Configuration Tab and the READ button is pressed, the following message appears:
Failed to enter command mode
Unable to read Version (ATVR)
Read parameters failed
Although the “read parameters failed”, when “+++” is entered into the Terminal tab field I get gibberish: FF FF FF FF etc.
Has anyone come across this before and been able to solve it? Do you think it could be my bad soldering?
Please note: I verified that the problem does not lie with the XBee module. By inserting the XBee into an XBee Explorer USB, the XBee was detected successfully and I was able to communicate with it (using X-CTU).
No public wish lists :(
