Sara SFF R412M network registration issues

Hey,

I’m facing a problem where I cannot register to any network.
I’m located in Israel and I tried two sim-cards of two operators with no luck.

After struggling with the Universal Tracker I tried flashing the passthrough and run some AT commands. The main goal is to send GPS lat/long to my own server via http requests.

One important note: I prefer using 2G/3G (With 012Mobile as operator) but I’m ok with LTE-M or NB-IOT.

So I’m running:

AT

OK
ATI

Manufacturer: u-blox
Model: SARA-R412M-02B
Revision: M0.10.00 [Mar 28 2019 17:13:41]
SVN: 05
IMEI: 354679091574049

OK
AT+CGREG?

+CGREG: 0,4

OK
AT+CGREG?

+CGREG: 0,4

AT+CGREG?

+CGREG: 0,4

AT+CGREG?

+CGREG: 0,4

OK
AT+CPIN?

+CPIN: READY
AT+CGREG=2

OK
AT+CGREG?

+CGREG: 2,4

OK

+CGREG: 3

I tried connecting the battery and different antennas.
Not sure what to do from here.

Any help would be appreciated.

Hi @isaac,

If your simcard does not support NB-IoT or LTE-M then you will not be able to connect.
With the R412 you are able to connect to 2G, select 2G as your RAT.
AT+URAT=9

The other AT command should be the same for 2G or LTE-M

Use AT+COPS=0 to select the automatic operator.
Or change the “20404” in the force operator to your operator in the force command AT+COPS=1,2,“20404”

Best regards,
Jan
