GPy ValueError: band 8 not supported by this board hardware!
When i try to attach my GPy to NB-IoT band 8 in germany (1nce) with
from network import LTE lte = LTE() lte.attach(band=8, apn="iot.1nce.net")
it get the following error message on my GPy:
ValueError: band 8 not supported by this board hardware!
I upgraded my NB-IoT Modem successfully to the newest Version 41019 and the GPy has the newest stable firmware (1.18.2.r4) as well
Welcome to the SQN3330 firmware updater [1.2.5] GPy with firmware version 1.18.2.r4 Your modem is in application mode. Here is the current version: UE184.108.40.206 LR220.127.116.11-41019 IMEI: ...

Did I miss something? According to the patch news
"Added Check for LTE band support against both SW and HW versions of the LTE modem." (https://forum.pycom.io/topic/4630/stable-firmware-release-v1-18-2-r4)
my GPy hard- and software should support band 8 if I am not mistaken.
Does band 8 work for anyone? Has anybody struggled with the same error message?

@robert-hh ok thank you for your time !
@Tgasser If attach is sometimes successful, then the board is fine. The error I flagged is fixed in version 1.20.1, but that seems not to be available for download.

@robert-hh I have the FiPy model 1.0 but version 1.2 which is normally good no?
I read your topic ( FiPy, LTE: Regression error - no band 8 support ), I made the downgrade of the firmware to v1.20.0.rc11 and I got to connect on the band 8 but sometimes I still have the error that appears.
@harix What happens if you omit band=8 in the call of lte.attach(). If it is just the error I flagged, it should then work. The code will then listen on all supported bands.
@Tgasser If it is a FiPy 1.0, you have to send it back for replacement.

Hello @robert-hh , I just want to confirm that if I have the same problem and the same information that appears on the console, I have to send it back to unlock it? Knowing that I have the FiPy 1.0 V1.2?
Thank you :)

I can also confirm that the latest firmware (NB1-41019) that it does not work with "band=8"
@robert-hh ok, thanks a lot for your time.
I guess i have to wait until the other two boards return and test them instead.
@bqpd I had two FiPy boards which were exchanged by Pycom. The new firmware may report band 8 support when the hardware might not support it. The code checks for a specific modem version, and that might be wrong.
@robert-hh Ok, thanks for your responses.
I changed to V1.20.0.r9 now, but i still get the same Error.
Do you have any other suggestions why it would throw the
band 8 not supported by this board hardware!when
at!="RRC:showcaps"lists band 8 as supported?
My GPy is one of the newer GPys where band 8 support should have been included by delivery (i have not sent it back to unlock it).
One older GPy and a FiPy are on their way back to pycom at the moment.
Is your GPy one you sent back to get band 8 unlocked?
@bqpd I use at the moment V1.20.0.r9 and Sequans firmware 41019. Since then, no tricks. I also looked up the NbIot coverage in the Jena region. It has some white spots like every place, but in general it's good.
@robert-hh And have you upgraded your firmware to 1.18.2.r4 on the GPy and version 41019 for the Sequans modem yet?
I remember you said that it worked for you on an other thread (https://forum.pycom.io/topic/4079/fipy-nb-iot-1nce-telekom-de-germany-fails-no-band-8-support).
I also tested your code with the older firmware and tried for 45 minutes to get a connection, but that failed in the end.
But at least i could run the
lte.attach(band=8, apn="iot.1nce.net")command back then.
Now with the newest firmware I get the error stated above when trying to attach (
ValueError: band 8 not supported by this board hardware!)
@bqpd I can confirm that band 8 works for me. The first attach took like forever (> 10 Minutes, long when you wait for it), but now it attaches after a power cycle within 10-20 seconds. Still slow compared to my other LTE module, which attaches immediately, unless it had been offline for days.
