Has anyone gotten an Arduino Fio v3 to work with an XBee yet? I’m having problems getting them to work together and can’t find any examples on the Internet of anyone using this revision of the product with an XBee, only the original Fio.
My setup is this:
I’ve already confirmed that the XBees are paired correctly and the char prints are will show up on the Pro’s X-CTU terminal if I transmit from an Arduino Uno + XBee Shield. It’s just the Fio v3 that doesn’t seem to work. Are there any differences between the Uno XBee Shield and the Fio’s built-in socket?
Exactly the same problem, all okay until I drop the Xbee in the Fio V3. Character goes out via the serial port when connected via usb but nothing when I run in stand alone.
Hi, sorry my post was delayed 24 hours due to moderators, I posted a further response but that seems to have been denied as a duplicate but I have now managed to get my Fio v3 working with Xbee by changing Serial.begin to Serial1.begin… My understanding is this routes the packets directly to to Xbee not out via the usb 
Hi, I just posted a similar problem with a WiFly RN-XV radio not seeming to communicate when simply plugged into a Fio V3. Are you still having success with the Serial1 solution? I had tried it last evening with Serial1, but with no success. I’m led to believe the WiFly is plug compatible with the Xbee radios, but I’m wondering if there’s some other issue. I simply want a Fio V3, RN-XV and battery to work standalone. No biggie, I thought! Thanks!
So…it seems at least with the WiFly module, there was no problem as long as I introduced a delay after the Serial1.print (or println) calls. Serial1.print turns out to be asynchronous and returns way before the serial message is actually sent. Once I introduced a 1000 millisecond delay, I had no problems whatsoever when I went to read the response from the radio. The darn thing works like a champ.
