FiPy NB-IOT Example Codes for beta network testing

[Bagraw]

Hi,

We happen to manage to get super early beta access to couple of NB-IOT SIM cards with one of the service providers in India (who probably are going to roll it out in next 3-9 months for public use).

I need help with example codes for testing the same with NB-IOT. (LTE-M is not available right away, but NB-IOT is available for select beta test). Can someone in the forum help me with it? I see that docs have not been updated on the same as they say, the same will be available in future.

Any help will be highly appreciated!

Thanks!

Hi @bagraw

For NB-IoT you need to follow this guide

https://github.com/pycom/pycom-libraries/tree/master/lib/sqnsupgrade

but note this is very early code and to use it you need to know details about the network you're connecting to, specifically:

Which eNodeB (basestations) are used?: Ericsson or Huawei. Huawei is not currently supported.

Which LTE band is the network in

What is the downlink EARFCN (or downlink frequencies)

We will be improving this setup in the coming months together with the modem manufacturer

I'm trying to to this, as we are running Ericsson eNodeBs on B20, but while starting the flashing process, I'm getting the following error:

>>> import sqnsupgrade
>>> sqnsupgrade.run('/sd/FIPY_NB1_35351.dup', 921600)
<<< Welcome to the SQN3330 firmware updater >>>
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/flash/lib/sqnsupgrade.py", line 72, in run
OSError: [Errno 2] ENOENT

If I check the sd card content with the commands described here, then I can see the file on the sd card: https://docs.pycom.io/chapter/firmwareapi/pycom/machine/SD.html

What could cause that issue?

@dariox Just curious, did you rename the FW file when you loaded it onto the sd card? By default the downloaded file is named 'FIPY_GPY_NB1_35351.dup', but you are calling it 'FIPY_NB1_35351.dup'. Of course, you may have simply renamed it ... the reason I ask is because the Usage example in the README.md does not match the default file name.

Hi @jmarcelino

Is pycom ready to support Huawei yet?

Actually, i'm trying to connect FiPy using NB-IOT code using telco sim card name Webe or unifi. Their are using band 5 and the downlink EARFCN is 2416. If not mistaken webe are using Huawei as their e-node-B and unfortunately the FiPY cannot attached to the network. Hope some body can help ;

@mfa2214 AFAIK @jmarcelino left Pycom last year, but for sure someone from Pycom Team will respond.

@mfa2214 We can support Huawei, but it depends what feature set the network operators enable to how well this will work :)

Hi all,

I'm trying to attach the "webe aka unifi" as network operators in Malaysia using band 5. unfortunately, modem still cannot attached and fipy also cannot listening the base station (Huawei e-nobe-b).

below is the error i got:

lte.connect()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: LTE modem version not read

lte.connect()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: modem not attached

Currently using FiPy-1.18.1.r7 as the modem f/w. Still do not know what happend. Hopefully someone could help. Many thanks
