NBIoT Support, lack of

[fherrador]

Just for your information.

NB IoT is being deployed in major cities in Spain by Vodafone, we have some Quectel units rolling

Cat M1 will be used and deployed in the upcoming Mobile World Congress in Barcelona by Telefonica Spain

@jmarcelino Count me in for testing! I’m in United States. I believe Verizon has CAT-M1 and NB-IoT coverage where I live. I am using hologram.
Let me know if you need anything else.

@jmarcelino Do you have any idea about when you will support Norway/Telia? And when the NB-IOT api will be available to use? I'm writing a master thesis on power consumption in IOT and want to do a comparative analysis of Lora vs NB-IOT. I already use Lopy's for the Lora part, but I'm looking into using the GPy or the FiPy for the LTE-M/NB-IOT part. Any updates in regards to estimates for everything needed to be able to start testing (firmware, software apis etc) would be highly appreciated :)

@jmarcelino Can we have an update on NB-IOT? Thanks

Hi,

How is the status of maybe supporting NB-IOT in Scandinavia? ... via Telia ? ...

They have announce global coverage in the entire Scandinavian region?

Even if you don't have support right now, we can assist, as we got FiPy modules and nano-sims from Telia and we got some good relationship with Telia and can recieve some help from their technicians :)

/Daniel.

Hello @kurt-renauer I am trying to set up my GPy with a T-Mobile Austria SIM without any success, I am quite new with this, so I after dig a bit in the forum post, I mash up something like this. However, I have not managed to connect to the network

lte.send_at_cmd('AT+CREG=1')
    print(".", end='')
    lte.send_at_cmd('AT+CGDCONT=1,"IP","m2m.nbiot.t-mobile.at"')
    print(".", end='')
    lte.send_at_cmd('AT+CGAUTH=1,1,"m2m","sim"')
    print(".", end='')
    lte.send_at_cmd('AT!="RRC::addscanfreq band=28 dl-earfcn=9410"')
    print(".", end='')
    lte.send_at_cmd('AT+CFUN=1')

I was wondering if you can give me any advice for achiving connection.

Hi @borbonjuggler, first of all you have to update your sequans modem and you absolutely need support of band = 8 in your sequans modem. For connection to NB provided by TMA it is absolutely necessary! Last year pycom invited gpy-customers to initiate an RMA process for the boards, because at this time it was not possible to activate band 8 by users. i guess that currently shipped gpy-modules should support band 8 (?). Once you have band 8 available, you can follow the NB-IoT tutorial on https://docs.pycom.io/tutorials/lte/nb-iot.html. As far as i remember, last time i didn't even have to use the apn-parameter and band-parameter - simply lte.attach() worked fine.
