ceiving stations. This last option instructs the receivers to reboot to a specific firmware revision
if available, and not already running at that revision.

Cancelling OTA Reprogramming

During the reprogramming operation the user has the ability to cancel reprogramming at any
time either on the initiator, which will affect all radios, or on individual receiving stations. Note
that cancelling reprogramming at the initiator results in all radios in the network having only one
(instead of two) applications programmed in their image banks. That is, the "inactive" image
(which was only partially upgraded) and will be corrupt and unusable until reprogrammed at a
later time.

Error Conditions/Recovery

Other than cancelling the reprogramming process, there are few error conditions that the initiator
knows or can do anything about. Receiving radios perform checks and verification on the incom-
ing data. If after the end of the reprogramming sequence a radio still has an invalid image (for
whatever reason) the radio will not reboot but continue running with its active, and valid image.
