Custom WP76xx serial numer



is there a place in WP76xx to store custom production serial number. We need to store a 11 characters long string.
We could store this in flash memory but I’m looking for some place that is independent on FW update/cleanup etc… is there some data storage available from Modem or other low level modules of WP76xx?



Can you explain what Is this custom production serial number - is it going to be unique for each module or for a particular release flashed in the module.
Also how do plan to update your firmware , which steps are you using.


Hi, thank you for interest.

Serial number should be unique for each module.

We would like to cover all update types .update, .cwe and .spk.

I guess problem is to preserve unique ID over spk updates?
