AT-Commands for NB-IoT

SARA AFF
1

Hello Jasper et al.,

I would like to use the new bought SODAQ Sara R410M in Austria inside the A1 network. I also have a Vodafone Card bought with it.

To get started I need to log on to the A1 Network or I need to use Roaming via Vodafone NL.

Could you please help me to enable the SODAQ SARA AFF R410M in Austria please?

Sincerly,
Andreas

P.S.:
I need something like this:

Vodafone NL AT Commands
After uploading the passthrough sketch use the following commands to send a message
These commands communicate on the NB-IoT Network of Vodafone NL

AT+URAT=8
AT+URAT?
AT+CMEE=2
AT+CGDCONT=1,“IP”,“nb.inetd.gdsp”
AT+CGDCONT?
AT+CFUN=1
AT+COPS=1,2,“20404”
AT+CSQ
AT+CREG=2
AT+CREG?
AT+CGPADDR
AT+USOCR=17
AT+USOST=0,“37.97.216.22”,3000,4,“Data”
AT+USOCL=0

Hi @Andreas_Runge

For the sim we provided you should use:
AT+CGDCONT=1,“IP”,“dev.sodaq.com”

20404, connect to the Austria operator id. 23201 looks like the correct one for A1 Austria

Kind regards,
Jan

Do you have a reference nearby for me to understand what the commands mean? What shall I do?
Sincerly, Andreas

Hi Andreas,

If i understood it correctly, you are trying to use a Vodafone SIM card on the A1 network.
Please not that for NB-IoT there is no widespread roaming yet.
Right now, if you want to use NB-IoT in Austria, I’d recommend talking to an Austrian operator and ask:

  • where they have NB-IoT coverage?
  • how you can have a SIM card?
    Cheers!

Hello!
I now use a A1 SimCard. A1 gave me an APN and a Password…

AT+CGDCONT=1,“IP”,“dev.sodaq.com” should be replaced by the APN they gave me?
I would be happy, to get an example how to connect to A1.

As I cannot connect yet, I would like to know which commands to send.
How can I check connection - for example a Ping in the A1 Network?

Sincerly
Andreas

Hi,
I found more commands for the NB-IoT at the link posted by Jan

The command to ping is AT+NPING="172.27.131.100" Where this IP adres is for T-Mobile. It depends on the network you’re using if you’re allowed to ping other adresses (8.8.8.8 google’s DNS server is allowed by Vodafone).
