Hi IoT friends!

A frequently asked question is the possibility to provide location services for NB-IoT to avoid the necessity of GPS. (Since GPS is reducing the battery life).

There are several ways to provide NB-IoT location services. And there are also several use cases which require location services.

I’d like to learn more about how our users want to apply location services.

E.g.

• To track your devices
• To see if your device is moving
• To get a notification if your device has moves

Would you like to share here what you want to use location services for? Please also tell us more about the accuracy and if you need the information real time, a couple of times per day, every 5 minutes etc.

Thanks!

Nadat het device een berichtje stuurt gaat hij een aantal milliseconden in connected mode an daarna een aantal seconden in idle mode.

Connected mode = voor het ontvangen van paging messages
Idle mode = voor het ontvangen van downlink messaged

Nu, in release 13, kun je idle mode op 0 seconden instellen. Straks, in release 14, ook de connected mode.

Hij wordt inderdaad ondersteund! Moet er wel bij zeggen dat deze modules nog niet zijn gecertificeerd voor ons netwerk, maar dat staat wel in de planning.

Leuk dat je 'm hebt besteld!

Spain confirmed!

Zo ver ik weet zijn er geen internationale afspraken over performance. Er zijn daarentegen wel theorieën over hoe de performance en prestaties van NB-IoT zouden kunnen zijn. Met nadruk op ‘kunnen’ en dus geen ‘moeten’.

Ik ben niet in de positie om te vertellen wat er voor andere providers of andere Deutsche Telekom landen geldt. Logisch zou zijn dat alle telecom operators NB-IoT aanbieden zoals het bedoeld is en waarvoor het concept ooit ontworpen is.

Er zijn volgens mij nog niet zoveel telecombedrijven die NB-IoT commercieel aanbieden. En van die paar telco’s die het al wel commercieel aanbieden, zien wij dat ze het als een ‘bit pipe’ aanbieden. Dat snappen wij niet zo goed. Dat was namelijk niet de bedoeling toen men aan de tekentafel stond voor NB-IoT.

Wij zien het in ieder geval als een dienst waarbij we de volgende zaken moeten aanbieden om van toegevoegde waarde te kunnen zijn:

• schaalbaarheid
• veiligheid
• duurzaamheid
• een lange houdbaarheid
• efficientie

Dit bieden we aan in combinatie met de mogelijkheid om 120 berichten per dag over en weer te kunnen versturen. Dit aantal is gebaseerd op de verschillende theorieën waar ik eerder in dit bericht over sprak en tevens bevestigd door de testen die we de afgelopen weken hebben gedaan. Deze vijf berichten per uur moeten ook altijd aankomen bij normale omstandigheden qua coverage.

Als ik iets nader moet toelichten hoor ik het graag!

That’s great news. Support for UDP passtrough is scheduled on our roadmap (apologies, only in Dutch). We aim to support UDP passtrough before the summer. However, if you are ready around the end of this month, we can test it on our PoC environment.

Please keep us posted!

Not all cells are updated yet. Apologies.

Just talked to my colleagues from our radio network team. It will take 3 hours from now before all cells will be updated

Werkt weer na het herstarten van een proces op onze connection and device manager.

Root cause volgt!

hmm no volunteers

So just send it to us. Will send you the address in a dm

New starterkit

In the past thirteen months we have provided starterkit simcards to many of you. Along with the simcard(s) you probably also received access to our IoT-network. Directly from us or maybe with assistance from our friends at Sodaq or All Things Talk.

Last week we said goodbye to our Early Access Program and our pre-commercial network. Yes, we are live now! But don’t worry, we still have a free starterkit and we’d love to provide you a new starterkit on our live network. With the new starterkit you will also enjoy the upcoming features of our network. Oh and by the way, you can still use the simcards which you already have.

How to check if you have the old starterkit or new starterkit?
Log in at https://portal.iot.t-mobile.nl. Don’t have an account yet? That also means that you don’t have the new starterkit.

Once you are logged in, please go to https://portal.iot.t-mobile.nl/projects. Here you can check if you have starterkit. Empty page? Then you don’t have the new starterkit.

If you have starterkit on this page, please check the startdate. If it’s from 25 april or later, then you already have the new starterkit!

You can get the new starterkit here and send an e-mail to rowan.schaaf@t-mobile.nl with your simcard numbers.

Document Library
Maybe you have already noticed that we removed the manuals from the forum. From now on you can find everything at https://docs.iot.t-mobile.nl. Feel free to send us your feedback!

That’s odd. This is the first time that I hear about this problem.

CFUN=1 means switchting on the radio module.

Maybe a capacity or power issue on the device?

Hey Sergey,

We do not have IMSI - IMEI lock configured. All our simcards should be able to work in mutiple devices. I double checked your sim-card configuration as well.

We do have some users who connected the nrf9160 via UDP…

@Eric-Barten (but he’s offline this week) and @Stefan-de-Lange

Thanks for the insight!

I’ll send you a new sim-card then.

Thanks! Just checked your sim-card settings and, everything looks fine from here.

Can you try it like this:

AT+COPS=1,2,"20416",9

I have to admit, I have no clue what the ‘9’ does. However, this is how @Roalnd-Baldin wrote it here in our doclib.

Hmm maybe! Can you send me the ICCID or IMSI via DM here?

Usually this really means that there 's still something wrong with reading the sim.

Can you please try what happens after removing and replacing the simcard in the card-holder?

I think that you did everything right. Something has changed at All Things Talk’s end. We received more complaints about integrations with ATT.

@Eric-Barten already contacted them, but I will give it another try next week.

@Sergey-Vladimirov thx for your enthusiasm!

For now only Quectel and Telit are “nuSIM - ready”. But soon more module vendors will be ready as well.

Check out: https://iotcreators.com/en/nusim/

PS. you also sent an e-mail with another question and we’re trying to get back to you but it looks like your inbox is not accepting new messages

Spain confirmed!

If you’re one of the lucky ones who received a nuSIM dev-kit from my colleagues Mona Parsa and Stefan Kaliner, you’re at the right place to find out how to get this super cool dev-kit online without a plastic simcard!

STEP 1: GET YOUR STARTERKIT PROJECT
Before using the dev-kit, you’ll need a starterkit project environment.

• Sign-up for it by using this link.
• When you’re asked about where to send the simcard select the checkbox of I already have simcards

STEP 2: GET YOUR DEV-KIT ONLINE

• Go to your project
• Register the IMEI of your device
• Attach to the network by using cdp.iot.t-mobile.nl as APN and 172.27.131.100 as gateway for a ping test or to send your uplink messages
• Your uplink payload should appear in the ‘device management’ tab of your project page
• If you do not know how to attach to the network, check out the AT-commands below

AT-COMMANDS TO ATTACH TO THE NETWORK

Switch-off the radio module

AT+CFUN=0

Configure basic connectivity parameters

AT+NCONFIG="AUTOCONNECT","TRUE"
AT+NCONFIG="CR_0354_0338_SCRAMBLING","TRUE"
AT+NCONFIG="CR_0859_SI_AVOID","TRUE"

Set the APN

AT+CGDCONT=0,"IP","cdp.iot.t-mobile.nl"

Set the band

AT+NBAND=8,20

Select the Operator

AT+COPS=1,2,"26201"

Telekom Germany = 26201
T-Mobile Netherlands = 20416
T-Mobile Poland = 26002
Or use the PLMN ID of any other operator within our NB-IoT roaming footprint

Switch-on the radio module

AT+CFUN=1

After not more than 30 seconds, your device should be attached to the network.
Now you can proceed with registering the IMEI number of the module in your starterkit-project and send your Hello World uplink message!

To follow the AT-commands below, it is important that you register the IMEI as UDP.

AT-COMMANDS TO SEND YOUR UPLINK

Open local UDP-socket

AT+NSOCR="DGRAM",17,7000,1

Send your uplink-message (2x)

AT+NSOST=0,"172.27.131.100",15683,11,"48656c6c6f20576f726c64"

Make sure to send it twice, in order to see your message in your starterkit project.

That’s it!

Feel free to reach out in case of any questions!
