Problem connecting Thingy:91 to cloud

RE: Problem connecting Thingy:91 to cloud

Hello Maciek,

Sorry for the late response.

1. One thing I know for sure is that the iBasis SIM Card doesn't work here.

2. I have some mixed feelings about iBasis feedback, they've been passing me from person to person, and they keep repeating me to do the same steps over and over when I've said multiple times they do not work .... so the problem is still unresolved. Since I'm working in multiple things at the moment and this isn't that important for me right now, I'm putting this on standby, but when I get back to it, I'll probably try with a local ISP card, if it still doesn't work I'm probably moving to another product from someone else ...

3. As for the LTE-M network in Portugal, I've searched everywhere and it doesn't seem there is any launch yet (compliant with the AT responses from the Thingy 91), only NB-IoT seems to be available but unreachable. The thing is, even if NB-IoT is the only available in Portugal, I wouldn't be surprised if only the 3 big ISPs here (NOS, MEO and Vodafone) were able to work in these bands, since they are pretty much the ones that launched them so they capitalize all the market here.

Most likely the only solution is getting some kind of subscription for a pack of IoT Sim cards from one of these ISPs (which is the solution most ISPs give), but from what I've seen in all of their 3 websites, there isn't many information about NB-IoT solutions other than "closed" solutions provided by themselves, which I do not want.

Best regards,

Saul

Hi Saul,

Did you manage to get it to work? Any feedback from iBasis?
I'm asking because I've also had only unsuccessful attempts to register to the network in Portugal. I tried using the Hologram SIM card and never got the LTE registration working, neither in LTE-M or NB-IoT mode. The same SIM card worked perfectly well in Poland and in Norway.

This led me to think that maybe portuguese providers allow access only for their own SIM cards (which, by the way, are almost impossible to get for a foreigner).

I will be grateful for some info about that, as I would like to work on some projects in Portugal.

Regards,

Maciek

Hello Saul,

Okay, as you wish :-)

Let me know if I can help you with anything else!

Hello Markus,

I don't really see this going anywhere though.

As it doesn't seem to be the firmware, since the images are the original, I should be getting some information, unless the SIM isn't working / no networks available.

I'll wait for iBasis feedback about the SIM, then we continue I guess.

Best regards,

Saul Carvalho

Thanks a lot for the feedback, Saúl!

I’m honestly a little bit surprised myself that the log doesn’t give us more information. My apologies for that!

I wonder if we should update the Connectivity bridge on the nRF52840 as well before proceeding here?

That would be the file thingy91_nrf52_connectivity_bridge_2021-06-28_7a076c22.hex.

Hello Markus,

I cant seem to put it in SPM anylonger ...

Hello Saúl,

could you do me a favour and flash the at_client image?

Afterwards, please run the Testing procedure as described in the application guide.

This means basically enabling Automatic Requests in the LTE Link Monitor and then triggering the following commands:

2021-07-14T04:22:49.130Z DEBUG modem >> AT+CFUN=1
2021-07-14T04:22:49.172Z DEBUG modem << OK
2021-07-14T04:22:50.219Z DEBUG modem >> AT+CFUN?

2021-07-14T04:22:50.234Z DEBUG modem << OK

This which will automatically launch a series of commands. It should look similar to this:

RE: Problem connecting Thingy:91 to cloud

Vaktan — Wed, 14 Jul 2021 08:26:12 GMT

Hello Markus,

For now I'm using the default config until I have it fully working, I will most likely do modifications after it is working though.

EDIT: I also sent an email to iBasis to check the validity of the SIM Card, seems some people had problems with that aswell.

EDI #2: I've also tried the asset tracker v2, here is the log.

RE: Problem connecting Thingy:91 to cloud

Albrecht Markus Schellenberger — Wed, 14 Jul 2021 07:35:16 GMT

Hello Saul,

no need to do that. In the log, the Asset Tracker is falling back to NB-IoT automatically:

2021-07-13T13:37:34.535Z DEBUG modem << [00:10:00.428,680] [0m<inf> lte_lc: Using fallback network mode[0m
2021-07-13T13:38:24.864Z DEBUG modem << +CEREG: 2,"B8CE","00060D71",9

Value 9 is:

<AcT>
9 – E-UTRAN NB-S1

which is NB-IoT.

That ends of course with the recject cause 15:

2021-07-13T13:38:27.538Z DEBUG modem << +CEREG: 2,"B8CE","00060D71",9,0,15

Cause #15 – No suitable cells in tracking area This EMM cause is sent to the UE if it requests service, or if the network initiates a detach request, in a tracking
area where the UE, by subscription, is not allowed to operate, but when it should find another allowed tracking area or location area in the same PLMN or an 
equivalent PLMN.

But I’m a little bit confused what is happening here honestly:

2021-07-13T13:27:34.344Z DEBUG modem << [00:00:00.335,144] [0m<inf> asset_tracker: Connecting to LTE network.[0m

2021-07-13T13:37:34.502Z DEBUG modem << +CEREG: 0

I can not see any more information on the connection attempt. It should be as much as when trying to connect to a NB-IoT network.

Are you using the default configuraiton of the Asset Tracker, or have you changed anything?

Markus

RE: Problem connecting Thingy:91 to cloud

Vaktan — Tue, 13 Jul 2021 14:00:30 GMT

Hello Markus,

Yes, I have been following the steps, I forgot to say that I have an Asset Tracker LTE-M configuration in the Thingy91 at the moment.

I have updated the certificate as said.

I can't get to step 7 since the device never connects to cloud, therefore I can't add the LTE device.

The last part of the log only appeared now. Before, it kept spamming the terminal with the SPM.

I'm also noticing now that it seems to be stuck on trying to connect to LTE-M, as it is trying to connect every 480 seconds.

Either the card is invalid or I do not have LTE-M coverage here.

I could try with a NB-IoT config aswell but iBasis SIM Card doesn't seem to have NB-IoT support in my country (Portugal).

RE: Problem connecting Thingy:91 to cloud

Albrecht Markus Schellenberger — Tue, 13 Jul 2021 13:05:39 GMT

Hello Saul,

to start with, you should check the following things:

Has your device successfully connected to the network?
Have you updated the device with the nRF Connect for Cloud certificate?
Have you been following the steps described in the Testing chapter of the nRF9160: Asset Tracker application guide? And here, especially point 7, where you manually have to add your Thingy:91 as a LTE device to the nRF Cloud.

Regards,

Markus
