Modem updating

[kjm]

Trying to download the latest modem firmware at https://software.pycom.io/downloads/sequans2.html But the id/pwd at https://forum.pycom.io/topic/4020/firmware-files-for-sequans-lte-modem-now-are-secured don't work. Why does this have to be so hard?

@kjm Everything is fine with given credentials (I've just checked). Anyway, you can use my prv repo

tnx muchly, does any one have a link to the latest approved method for modem upgrading?

@kjm The modem updating method from the docs worked for me. Not trusting the UART link, I chose update via SD card.

[rskoniec]

@kjm I'm also using SD card, always with full update method (not upgdiff dup file) and with pycom.lte_modem_en_on_boot(False).

[kjm]

@robert-hh There are so many docs of different vintage online, can you give me a link to the one you actually used please.

@kjm For example here. Be sure that you have the latest board f/w installed, so automatically you'll have the latest version of sqnsupgrade library. After fresh board start with pycom.lte_modem_en_on_boot() set to False I'm doing the procedure like below:

from machine import SD
import sqnsupgrade

sd = SD()
os.mount(sd, '/sd')    # mount SD card
os.listdir('/sd')      # list SD card content to verify that files are accessible
sqnsupgrade.run('/sd/modem-file.dup', '/sd/updater.elf')      # start upgrade process

@kjm I saw an e-mail notification about your post. You should use import sqnsupgrade without () at the end. Did you manage update your modem? Btw, newest stable f/w is 1.18.2.r7 according to this link.

@rskoniec Yeah, got there eventually https://forum.pycom.io/topic/4999/gpy-modem-upgrade-alternative
