3-270 AT Commands Reference Manual June 30, 2008
Firmware Update Over the Air (FOTA)
The following paragraphs describe the use of AT commands for updating the G24 firmware over
the air.
Note: FOTA is enabled in modules with SW version G24_G_0C.11.B2R or later, when web
session is well configured by +MFOTAWSCFG command, in accordance with your
carrier required settings, to allow data connection.
The update process is done by communication between the G24 and the versions server.
Duringthe process, the servers sends both SMSs and data over GPRS connection to the
G24.
During the process, the data connection will be opened and closed for several times.

+MFOTAWSCFG, Set the Web-Session Default Entry

This command enables Web-session default entry setting.
This command is a non-basic command, which means that the G24 rejects the command with an
appropriate error message when the SIM is not present and/or the phone is in lock state.
In MUX mode, this command is allowed on DLC2 only.
In order to enable a client to connect to a server (for example: Bitfone/ RedBend servers), default
Web-Session must be configured in the client.
All AT+ MFOTAWSCFG settings will be saved in nvm and the la st setting will be available after
power up.
Note: The user can reset one of the optional parameters (i.e [user name], [password], [proxy])
by submitting an empty string as its value. See an example below.
