Enable NBIoT on up-to-date firmware?
-
Hi, having some real trouble here - could use some help.
It took a while to understand the laberynth of documentation for upgrading my FiPy modem to enable NBIoT (I'm in the US, using Twilio SIMs on the T-Mobile NB network) and I've uncovered this problem.My modem version shows:
>>> import sqnsupgrade >>> sqnsupgrade.info() <<< Welcome to the SQN3330 firmware updater [1.2.6] >>> >>> FiPy with firmware version 1.20.2.r0 Your modem is in application mode. Here is the current version: UE5.0.0.0d LR5.1.1.0-47510 IMEI: <redacted> >>>Which mean I am apparently only enabled on CatM networks? I'd like to update firmware to enable NBIoT but according to the latest firmware available for download it's actually a downgrade from v47510 to v41019.
Is that a problem? If I continue will I brick my $80 device? Does the FiPy only work in CatM OR NBIoT mode, not both at the same time? Will someone please put some effort into writing clear documentation?

Wanted to provide a quick update to this.
I just received an NBIoT specific SIM from Twilio.
Was excited to test it now that I have the NBIoT specific firmware & correct SIM enabled, but I'm getting this strange behavior. The SIM is active and confirmed by Twilio, but for some reason I am quickly disconnected. Has anyone seen this behavior before? Does anyone know some definitions around the FSM readout? It's strange because this readout seems identical to the first successful attempt with a non-NBIoT SIM.
It feels like Twilio is rejecting the connection as I have signal and the connect attempt appears successful, but was hoping someone might be able to confirm.

The modem firmware shipped from the factory (47510) is, according to our testing, exactly the same, and if anything, slightly worse, compare to the 41065 version for CatM1 we have out there, which is why we have not published the 47510 firmware (higher is not always better).
Now the difference between CatM1 and NB-IoT firmwares is quite big. Where CatM1 firmwares start with LR5, NBioT is at LR6. This has nothing to do with the actual differences between the firmwares, and it does not mean the NBIoT firmware is in any way behind in development to the CatM1 firmwares. It is like comparing apples with oranges.
I have put effort in clearing this up over the last few months (https://docs.pycom.io/updatefirmware/ltemodem/ and https://docs.pycom.io/tutorials/networks/lte/), but apparently, not clear enough yet.

Sorry to hear you have problems, I have been asking for an up to date NB-IoT driver for months in another thread and reached out to Pycom in June. I am stuck with LTE CAT-M1 at the moment as there is no, to my knowledge, clear solution to this matter. I would like to see a fix as well, but I have lost my hopes for a solution.

@kjm said in Enable NBIoT on up-to-date firmware?:
@barryjump The problem with putting NBIot on your modem is you can never get back to the catM1 version that it shipped with! You're stuck with 41065.
I really hope that isn't true! If it is, I'll reiterate my plea to Pycom to step up their clear documentation game. That's an insane oversight to not communicate clearly.
