Fmm920 not sending data

Hello,
I’m doing some first test with the FMM920 I recently bought.
I’ve configured it for the use with the NB-IOT network.
The simmcard I’ve inserted is specially bought for this use
The device has found his position.
With the settings described below here, it is not sending any data.
I hope there is somebody can tell me what possible causes can be?

I’ve inserted the simmcard and there seems to be a good connection when I look at the status page from the Teltonika configurator.

The only thing that triggered my attention is the GPRS status being deactivated . Since NB-IOT uses 3,4 and 5G this seems logic, GPRS is 2G.

The device must send its data to a public requestbin with a HTTPS URL: ‘https://enamplb2hoa1.x.pipedream.net. I’ve set this in the GPRS settings’

For the test I’ve set Data Aquisition on stop to every 60 seconds.

I’ve set networksettings to NB-IOT

I hope somebody can put me on the track, what can be the cause the device does not do any attempts to send data with these settings.

Hi Peter,

Good day, and welcome to the Teltonika Telematics community forum.

From your screenshot, it seems the operator code is already detected.

Can you please check the record-saving settings?

Kindly select Always option for your testing, If there is no GPS satellite signal in your location, always means records will always be saved and sent it to your server even without a location fix and no time sync, on the other hand, you can also select After time sync ,

For your reference please check our wiki page: FMU130 System settings - Wiki Knowledge Base | Teltonika GPS (teltonika-gps.com)

Hi Maynard,
Thank you for your response. my apologies for this late response. I’ve changed the setting as you suggested. I Also disabled de sleeping mode. And changed the data protocol to Json.

At the status, I can see, the device did find his position and signallevel is Good Signal

Unfortunately the device still does not send any data.
Do you have other suggestions ?

Kind Regards
Peter

Hi Peter,

Kindly follow the steps below.

  1. You need to implement the codec 8/codec 8 extended to your server: Codec - Wiki Knowledge Base | Teltonika GPS (teltonika-gps.com)
  2. If a codec is not yet implemented to your server you can try to use flespi.io , you may create a trial account and connect up to 10 devices, 5 devices for each server.
  3. Also make sure that the data subscription is activated in the simcard that you are using.

Best Regards,
Maynard C.
