OTA LTE modem update

[DonovanBlackLab]

Hi,

Is there a way to update my LTE modem's firmware over the air?
I'm guessing that I'd need an SD card to write to first (using CAT-M1), and then do the update from there? Ideally, I would like to do this safely without UART/SD.

I'd much appreciate some guidance on how I would approach this. Also is this something that's indeed necessary/ wise/ advisable?

Thank you in advance

@DonovanBlackLab The documentation is a bit vague. After a lot of trials, I was able to upgrade firmware from the module's flash over wifi (no UART, no SD). I copied one of the diff file into the /flash over ftp (I used FileZilla GUI Client). And in the micropython REPL execute following code:

import sqnsupgrade
sqnsupgrade.run('/flash/diff_file')

You should copy the diff file based on your current modem firmware version which you can check with,

sqnsupgrade.info()
