Worried a radio module has given up the ghost? Digi XCTU can bring it back to life. Perhaps a designer has set their Digi XBee® for extended low-power sleep, an unusual baud rate, or some other change that makes it temporarily unresponsive. Even if the problem is corrupted firmware, Digi XCTU’s XBee recovery tool can force an update to bring the Digi XBee back to life, good as new.
