Resetting Old (Pre-Reset Button) Explorers
When it's having trouble communicating with an XBee, XCTU may present you with a notification like this:
The USB explorers were revised in May 2014 to include a reset button, so resetting should be easily done on those newer boards.
However, if you're using an older Explorer you'll have to use the "jumper method". Grab a piece of jumper wire and, when prompted with
the "Action Required" window, briefly connect the RST pin to GND.
Short them together for about a second, and then remove the wire. If you've done it within the time window provided by XCTU, it should
proceed to the next step. If not give it another try...it takes some practice.
