New CAT-M1 & NB-IoT Firmware (10 July 2018) Upgrade Failure

[le_wildfox]

Hello all,

I'm currently using GPy
I noticed that there are updates on the firmware as of today 10 July 2018:
https://software.pycom.io/downloads/sequans.html

I successfully performed update with the new CAT-M1 fw (36417.dup) as in below log:

	Deploying the upgrade (DO NOT DISCONNECT POWER!!!)...
	Resetting (DO NOT DISCONNECT POWER!!!).
	..
	Upgrade completed!
	Here's the current firmware version:
	UE5.0.0.0d
	LR5.1.1.0-36417

When I tried to continue upgrading with the new NB-IoT fw (NB1-37365.dup)
The process got stuck at this point (Resetting...) for more than 10 minutes:

>>> sqnsupgrade.run('/sd/FIPY_GPY_NB1-37365.dup', 921600)

Anyone got the same issue?

Cheers!

@xykon Can you list what bands are now supported? I've tried Band 8 using addscanfreq, but the device does not search for a network: CEREG is stuck at 0, "not registered, MT is not currently searching an operator to register to".

@xykon
Any estimation for implementation of PSM and eDRX?

@administrators any updates on this?

[Eric Waai]

@xykon

are there any release notes for the new firmware.
is there already support for guard-band networks?

is there a list of what networks are supported?

@xykon Fantastic! Gonna try to upgrade now. Will comeback with the result.

Upgrade looks good:

	Here's the current firmware version:

	LR6.0.0.0-37781
        OK

@Xykon Is there any change on sequence to connect? Or is it still the same as previous version? I have something like the below snippet, but haven't had the chance to try in the actual NB-IoT network. I have to go to Vodafone's lab to test it. Looking forward for your suggestion.
Thanks.

print("Trying to connect to nb-IoT network...")

    send_at_cmd_pretty('AT+CFUN=0')
    send_at_cmd_pretty('AT!="clearscanconfig"')
    send_at_cmd_pretty('AT!="addscanfreq band=20 dl-earfcn=6253"') #band & earfcn
    send_at_cmd_pretty('AT!="zsp0:npc 1"')
    send_at_cmd_pretty('AT+CGDCONT=1,"IP","nb.inetd.gdsp"') #apn
    send_at_cmd_pretty('AT+CFUN=1')

    try:
        while not lte.isattached():
            time.sleep(1)
            print('Attaching to network. Status: ')
            send_at_cmd_pretty('AT+CEREG?')
     

        lte.connect()

        while not lte.isconnected():
            time.sleep(1)
            print('Establishing bearer...')```

A new NB-IOT firmware 37781 is now available. I have also updated the upgrade scripts so please make sure you fetch the latest version.

@kevin

Thanks for responding.
Absolutely agree, I also tried couple time. Looks like this part seems to be the cause:

Deploying the upgrade (DO NOT DISCONNECT POWER!!!)...

After this part, reset always failed.
As in your case, I also had to do manual hard reset ( by sending AT^RESET) then downgrade the NB-IoT FW back to 35351.dup

Not sure what to do next then. Waiting for official announcement and/or fix?

@le_wildfox Yes, I have the same issue, as you also saw in https://forum.pycom.io/topic/2902/cellular-radio-firmware-release-sqn3330-for-both-cat-m1-and-nb-iot/43. I'm replying here since it is a newer thread.

I tried the upgrade several different ways (from SD card, from PC, starting from various baseline FWs, etc.), but always with the same result.

Manually stepping through the sequence in sqnsupgrade.py, I see that the AT^RESET which follows AT+SMUPGRADE does not return the expected result. There is never a +SHUTDOWN response, which is why the script hangs. I guess the new FW did not load correctly? After a power-cycle, many AT commands do not work (including ATI1), I have to re-load the older FW.
