Properly configuring, saving, and restoring user image profiles
Here is an example of how to properly manage the user image profile AT commands.
Example: The module by default boots up in User Image Profile 2, which is packet
data mode. This example will back up Profile 2 into Profile 1 for safe keeping, then
change Profile 2 to become Circuit Data, and save these settings permanently into to
Module ROM so that the module boots up into Circuit Data mode.
Changing the settings of a user image
1) Make User Image 2 the active image: ATz2
2) View stored parameters to verify: AT&V
3) Save Profile 2 to Profile 1 for safekeeping: AT&W1
4) Now make User Image 0 the active image so parameters can be copied: ATz0
5) Write the Profile 0 parameters to Profile 2: AT&W2
6) Make User Image 2 the active image to verify the change took place: ATz2
7) View stored parameters: AT&V
The module will now power up in Profile 2, which was customized to be in circuit
data mode by the above example. To recover Profile 2, do the following steps:
Restoring the settings of a saved user image
1) Make User Image 1 the active image to recover the Image 2 profile data: ATz1
2) View stored parameters to verify: AT&V
3) Save Profile 1 to Profile 1 for safekeeping: AT&W2
4) Make User Image 2 the active image to verify the change took place: ATz2
5) View stored parameters: AT&V
