<![CDATA[Failed to start STP mode!]]>This is what im getting on my computer(Ubuntu 16.04):

>>> import sqnsupgrade
>>> sqnsupgrade.run('/dev/ttyUSB0', 'NB1-40343.dup', 'updater.elf')
<<< Welcome to the SQN3330 firmware updater [1.2.0] >>>
Failed to start STP mode!

Edit: I'm running this on my computer and I opened as "sudo python3"
Edit 2: I'm trying to do this over UART since i don't have the expansion board aka no sd card.
Edit 3: Tried to do also upload the 'upgdiff_33080-to-40343', same result as I have here.
thoughts?

Where are these files located? Are they accessible directly or do they need a path like /sd/updater.elf ?

ccessible Sorry, I didn't specify enough, that is a python console opened on my computer in the path of the sqnsupgrade and NB1 files.

But you were successful once the files was on the module?

I am getting the same error message from the sqnsupgrade script.

I did manage to upgrade the modem to nb-iot using the uart method.

The key was to

  1. use the "diff"-file and
  2. leaving out the parameter to the updater.elf file in the method call sqnsupgrade.run(...)

Your modem has been successfully updated.
Here is the current firmware version:

UE6.0.0.0

When I tried your method (to upgrade) the result was an error:

Upgrade failed with result failure[diffUpgrade,239] Patch didn't apply!

So I figured I'd just upload the final image rather than a diff as the factory shipped firmware appeared to be some unknown number (46470)

The documentation on all this is convoluted when its probably quite simple.
