Driver’s FOB Out-of-Range
‘Disconnect’ from BTCS is used to signal to LMU that driver’s ID is no longer valid.
option 1) New/existing Peg trigger to allow peg to decide to rescan () and send a logoff message to
server.
option 2) If Ignition is still on, rescan automatically and follow driver ID discovery process.
option 3) Both of the above
Over the Air Update
Note that it is possible that a different fob could be connected after an OTA upgrade, and so the next
ID report for the upgraded fob will not be until the next time it is used.
