Device Check-In
The device check-in feature provides connectivity to "configuration-only" servers. The device performs a
“check-in" to these servers periodically for configuration updates. A check-in is similar to a wake-up
message. The server then configures the device using AT commands after establishing a UDP
connection.
This feature has AT$CHKIN command available and requires Novatel Wireless CMS software version 3.1
or higher. For more information, see MT 4100 R ATCommand Reference (MT4100R-AT144) or MT4100
UATCommand Reference (MT4100U-AT144).
