I ordered 3 identical Series 2 Zigbees. Months ago I easily got 2 of them talking together, as shown by Adafruit's great little backpack with the red/green status LEDs. I then simply hooked the API's RX->TX and TX->RX on a Mega and read all the serial data being transmitted from the AT to the API. The AT burnt out, I replaced it with one configured exactly the same in XCTU, they talk to each other like normal (red LED goes on) but I cannot seem to get any data to the Arduino serial terminal! Help!
Worth noting, the API xbee no longer is recognized directly by XCTU. I can only configure it by switching my Router AT to a router API, then "detecting other units in the same network". So why can I only configure the API remotely? Why does the software not recognize it directly? It says "no bootloaders found" when I try Recovery on the API. Range test works great, shows packages sent/received between the two. Did I somehow fry the API's serial capability while leaving everything else intact? Please help!
I've tried everything i can think of to get this API talking, including swapping it to a router AT (via remote programming through the brand new, functioning, Router AT-turned-Coordinator-API...). So I essentially swapped the two Xbees' networking roles and STILL the same physical Xbee is unreachable directly. I'm at a loss on how everything but serial comm can function in a unit.
