Receiving stations can automatically reboot to the new image after suc-
cessful reprogramming. Alternatively, there is an OTA reboot command
that can be broadcast from the initiator to all receiving 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 anytime either on the initiator, which will affect all
radios, or on individual receiving stations. Note that cancelling repro-
gramming 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) 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 incoming 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.

Execution and Screen Examples

Displayed information during reprogramming (at Root radios):
• (Percent Complete—Read-only): This parameter indi-
Progress
cates percent complete of a firmware upgrade. The calculation is
done each time a block of data is successfully transmitted or
received.
Command options available during reprogramming (at Root radios):
• —Terminate remote firmware upgrade for all remote nodes
Abort
in the network. Inactive images on non-root radios will be invalid.
(No change to status of root radio images)
• —Manually send a reboot to all remote nodes in the net-
Reboot
work. All remote nodes will reboot to their inactive image, unless
already at the desired version of firmware chosen to reboot to, or
if neither the active nor inactive image is equal to the desired ver-
sion.
Command options available during reprogramming (at "Non-Root"
radios):
• —Terminate Remote Reprogramming for local radio. Inac-
Abort
tive image will be invalid.
