Non Volatile Memory Unsolicited Message +WNVM
Description: This unsolicited response is used to indicate various Non-Volatile Memory (NVM) events. The
messages will only be presented during the startup sequence; before receiving +WIND:4.
Synchronization at startup may occur if the modem was improperly shut down before an NVM
synchronization between primary NVM storage and secondary NVM storage was completed.
If during startup it is determined the primary NVM storage is not usable, the modem will boot from
the secondary copy. This insures reasonable notification that the modem has started and is
taking the necessary actions to correct the primary NVM storage.
Results Example:
+WNVM: 1
+WNVM: 0
Supported Events:
0 Synchronization stopped, Primary NVM storage to Secondary NVM storage
1 Synchronization started, Primary NVM storage to Secondary NVM storage
2 Primary NVM resulted in an error, booting using the secondary NVM image
