USB Serial number

In normal mode the USB serial number might be
But during firmware download it changes to

Which is the same as le_info_GetPlatformSerialNumber()
Is there any command that returns the other Serial number ?

Is it the same as ati3?
Here says le_info_GetPlatformSerialNumber() should get the FSN as in ATI3 of module:

No it’s not the same in normal operations

ls -l /dev/serial/by-id/
usb-Sierra_Wireless__Incorporated_Sierra_Wireless_WP7702_60ffb685-if00-port0 → …/…/ttyUSB0

i think that one in USB has no relationship with the module serial number…

I think so too,
but is there any command to get this ?

in my case, it is showing the FSN

owner@ubuntu:~$ ls /dev/serial/by-id/usb-Sierra_Wireless__Incorporated_Sierra_Wireless_WP760*

I think it might have something todo with /etc/adb_devid, (don’t know if you have this file?)
that file contains the other serial number
I will look in the yocto source and see if i can figure out what controls this file
