DEAR PEOPLE FROM THE FUTURE,
This is what we know so far:
I was struggling with the tutorial Ladyada has posted. It worked maybe 1 time out of twenty for me and more than a foot range. I tried all sorts of settings with the com port latencies and delays. Then I found this tutorial:http://www.seancarney.ca/projects/wirel ... rogramming
It seems like he has the Receiver/Transmitter settings flip flopped from Ladyada's. Oddly, this works with the hardware mods in Ladyada's tutorial? Maybe the settings are backwards in her tutorial but the hardware is still correct?
Also he has Xbee retries set for 3 on the receiver. I think the only other difference is he references the DIO Change Detect pin directly with 8 rather than FF. I suspect the retries is the important difference, but I also applied these settings with AT commands through the terminal rather than with the XCTU settings as I had been doing. Seems to be working perfectly now.
Setup: win 7 64bit
Xbee Series 1 - 1 mW Wire
Adafruit Xbee adaptors
Adafruit FTDI Friend ( do you not have one of these? you should have one of these.)
