Thingy91 Asset Tracker demo: stuck at no LTE connection

bluebeam

Hi Nordic support,

I was trying to get the Asset Tracker app running on the Thingy91 device but encountered various problems. Basically it can't get connected with the network. Here's the details.

1) I followed the getting Started video to update the modem firmware and app firmware.

Modem firmware: mfwnrf9160123.zip

App firmware: thingy91_ltem_2021-03-04_8e8c6089.hex

I used the Nrf connect desktop app and USB connection, not debug probe to update the firmware.

2) I created nrf cloud account and activated the iBasis sim card. But it won't let me add the device, with this message:

"There was an error adding your device: No device found for this id. The device has not yet been provisioned. Troubleshoot nRF Code 40412"

I turned on the Thingy91 device, it blinks cyan forever.

I turned on the LTE link monitor. The log message shows it can't make a connection to the network. I'm here at US west coast with pretty good LTE signal. Cell phone shows 3 or 4 bars. iBasis's website says we're covered with LTE-M.

I attached the LTE link monitor logs below.

3) Then I went back to the "device has not yet been provisioned" part. Nordic's document says you don't need to do it manually if you have a newer device. My device says PCA20035 1.4.0. But I did it anyway since I don't know what else to do. I downloaded the certificate(the json file) from Nrf cloud, and loaded it to the Thingy91 using the LTE link monitor. It says succeeded but blinks red. I assume that's because it's in offline mode. I power cycled the device. It doesn't make any difference. There's still no LTE connection, and I can't add the device to the Nrf cloud because "it hasn't been provisioned".

So I'm stuck here. Not sure what I missed or how to trouble shoot it. Please take a look and tell me what's wrong here. Thanks!

    Hi , 

    Sorry to hear you are facing these issues. Thanks for providing valuable information to find the root cause of this issue. 

    I'm here at US west coast with pretty good LTE signal. Cell phone shows 3 or 4 bars. iBasis's website says we're covered with LTE-M.

     What network does your cell phone connect to? 

    Based on the CEREG information throughout the logs:

    //Connecting to LTE-M
+CEREG: 2,"2C46","014B8517",7,0,11,"11100000","11100000"
+CNEC_EMM: 15

+CEREG: 4,"FFFE","FFFFFFFF",7,0,15,"11100000","11100000"
+CEREG: 2,"2C46","014B8517",7,0,15,"11100000","11100000"
+CNEC_EMM: 11

lte_lc: Using fallback network mode
//Connecting to NB-IoT
+CEREG: 2,"EB08","014AF3CA",9,0,15,"11100000","11100000"
+CNEC_EMM: 11

+CEREG: 2,"9240","066E4D39",9,0,15,"11100000","11100000"
+CNEC_EMM: 15

    The network that the iBasis SIM is trying to connect (Roaming) rejects the connection. The device tries for a given time to connect to LTE-M network. It then shifts over to NB-IoT. Both network rejects. See +CEREG chapter in the AT Command Reference guide.

    From 3GPP TS 24.301 Annex A:

    Cause #11 – PLMN not allowed
This EMM cause is sent to the UE if it requests service, or if the network initiates a detach request, in a PLMN
where the UE, by subscription or due to operator determined barring, is not allowed to operate.


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.
NOTE 3: Cause #15 and cause #12 differ in the fact that cause #12 does not trigger the UE to search for another
allowed tracking area on the same PLMN.

    Can please contact your local network provider and ask for a SIM that supports LTE-M

    Kind regards,
    Øyvind

    Thanks for your prompt response.

    We have AT&T, T-Mobile and Verizon here. They all claim to have either LTE-M or NB-Iot support.

    I'll get this card and give it try: https://marketplace.att.com/products/att-iot-dataplans-lte-m-us

    I'll come back and update whether it works or not.

    But meanwhile I'm puzzled why the iBasis SIM card doesn't work. iBasis website says it has U.S. national wide LTE-M support. That is supposed to make developer ramp up easier. Why it doesn't work?

    Also what do you think about the device not provisioned issue? Is that because the device hasn't connected yet and once it can connect the problem will go away?

    Thanks!

    Yes, I'm a little puzzled by this myself. I have contacted iBasis to see what can cause this issue. Can you please issue the AT Command %XICCID and send it along with the timestamp in a PM to me?

     

    bluebeam said:

     Correct, as the device is not connected to the network, it is not able to connect to the nRF Cloud to provision. 

    Kind regards,
    Øyvind

    I got the AT&T SIM card for their LTE-M service. I put the card in the Thingy91 and power it on. It just works. I'm able to connect to LTE-M network and send data to my nrfcloud account.

    So something is wrong about the iBasis setup. They'll need to figure that out.

    Thanks for the feedback! No news yet but will update you as soon as I have an update,

    Kind regards,
