@bettina Any news?

[peterv]

So today I managed to get a connection with the NB-1 firmware version 35351, haven't managed with version 37781 though. Here's what I used:

lte = LTE()
def send_at_cmd_pretty(cmd):
    response = lte.send_at_cmd(cmd).split('\r\n')
    for line in response:
        print(line)
send_at_cmd_pretty('AT+CFUN=0')
send_at_cmd_pretty('AT!="clearscanconfig"')
send_at_cmd_pretty('AT!="addscanfreq band=20 dl-earfcn=6400"')
send_at_cmd_pretty('AT!="zsp0:npc 1"')
send_at_cmd_pretty('AT+CGDCONT=1,"IP","nbiot.iot"')
send_at_cmd_pretty('AT+CFUN=1')
while not lte.isattached():
    pass

lte.connect()
while not lte.isconnected():
    pass

DNS doesn't work, but I managed to send some data through MQTT to Adafruit IO using the IP address for io.adafruit.com (as opposed to using the hostname).

[peterv]

It somehow started working with version 37781 too, managed to reduce the code to:

lte = LTE()
lte.send_at_cmd('AT+CGDCONT=1,"IP","nbiot.iot"')
lte.attach(band=20)
while not lte.isattached():
    machine.idle()
lte.connect()
while not lte.isconnected():
    machine.idle()

DNS is still not working (maybe related to https://forum.pycom.io/topic/2934/lte-nb-iot-dns/4).

Hi @peterv,

That's great that you got it working! There's an open issue for DNS on GitHub, as you can see there we are looking into the issue.

Any update on this one ?
Tried all the above using my GPY and an Orange Maker SIM Card, but no luck : can't get the LTE attached.

Apparently different APN's in use (cfr https://docs.allthingstalk.com/networks/use-orangebe-nbiot/ ):
You purchased an Orange NB-IoT Rapid Development Kit and SIM card: starter.att.iot
You purchased an Orange NB-IoT SIM card:
Maker: att.iot
Light: nbiot.iot
Plus : nbiot.iot

Any hints ?

Thanks,

Filip.

OK, it does work for Orange Belgium using the instructions @peterv provided (thx for posting them), but ONLY using NB-IOT firmware NB1-37781, not using the more recent NB1-38729.

Cheers,

Filip.

@peterv Do you have any news on newer firmware? With your code it started to work at some point on firmware 40343 without any changes that I know of. 2 days later, not changing anything, it stopped working..

@lonefish said in Orange Belgium Gpy:

40343

I will test once i success in flash the nb firmware.
By the way, I heard that LTE catM is being deployed on Orange

[rskoniec]

@mp Here in Poland Orange also deploying pilots with Cat-M1.

[mp]

My flash succeed!

In the first test device attache and connect quite quickly ( with csq = 16), but now with the same code it didn't work again (csq = 99,99). Strange, will test again later

[mp]

@Lonefish Do you find a solution?

Anyone else have some track to debug when the code is stuck in the isattached loop?

Or have the 35351 firmware?

[Lonefish]

@mp Apparently the SIM cards were deactivated, they deactivated the SIM cards after 3 months, and we didn't know. They are activated again and now it works again (firmware 40343)

I also heard the news that CAT M1 should be deployed, will test that out later this week.

[Lonefish]

The current state (22 Januari) of the Orange LTE-CAT M1 is this according to Orange B2B:
Only in Antwerp and around 20 sites it's available. The network is ready, but still waiting to activate it because of a few reasons apparently.

[mp]

Hey,
I still have trouble to connect to nbiot :s
Always stuck in lte.isattached loop.

I checked my sim card with the allthinktalks modem and the card is still activated.
I've tried the solution of peterv, annoguy, and in the official doc.
@Lonefish which solution did you tried ?

[mp]

Does anyone can help to figure out what going on ?
It start to be frustrating ....

[peterv]

Still works for me on 1.20.0.rc4/NB-IOT firmware 40343:

>>> import sqnsupgrade
>>> sqnsupgrade.info()
<<< Welcome to the SQN3330 firmware updater [1.2.1] >>>
>>> FiPy with firmware version 1.20.0.rc4
Your modem is in application mode. Here is the current version:
UE6.0.0.0
LR6.0.0.0-40343

and

>>> from network import LTE
>>> lte = LTE()
>>> lte.send_at_cmd('AT+CGDCONT=1,"IP","nbiot.iot"')
'\r\nOK\r\n'
>>> lte.attach(band=20)
>>> lte.isattached()
False
>>> lte.isattached()
True
>>> lte.connect()
>>> lte.isconnected()
True

Still no DNS:

>>> socket.getaddrinfo('www.pycom.io', 80)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OSError: -202

@mp My solution was making sure the SIM cards are still activated. That was it, the code just works. I suspect you have the antenna connected?

I have to say tho, the first time it seems to take a while to connect (like a few minutes even) but after that it just 'flies' through. Have you let it sit for a while? Like during lunch?

EDIT: Have you updated the firmware to the latest version?

[johanbrichau]

@mp I have my Gpy connecting to Orange NB-IoT. I’m using latest dev firmware and modem firmware. See https://github.com/jbrichau/TrackingPrototype/blob/b3c5ec0cd3a7cd434fb6cec64c85c206d8d3277e/Device/main.py#L75 for my code.

What is the firmware you are using?

[mp]

Hello all,
I use 40343, but it was painful to flash the firmware, is it possible that the firmware is corrupted? If upgrade success the firmware have to be ok?

Yes i let it connected many minutes, and the antenna is connected. I dont use this anthena https://pycom.io/product/lte-m-antenna-kit/ but another nbiot antena (https://shop.sodaq.com/sodaq-sara-ubee-n211.html)
I will retry this Sunday

Thank you for you help
