2. Check server address where the data are being sent to

Checking the server address can be done by sending a text (SMS) message to the module. Here is a list of commands. Please make sure you write them exactly as they are. They are case sensitive. Engine must be turned on.

First check where the data are being sent to with following command:

stele:settings

You should receive reply. The info that we are looking for is after IP:

860906041739696;Pgmd:10,Pgsm:60,Hdg:15,Dist:500,Tign:60,TnoIgn:-1,MSpd:15,IP:s1.stelematic.com/v1/module:8020

The correct address should be: s1.stelematic.com/v1/module:8020, if you see anything else you can change it with the following command:

stele:server=s1.stelematic.com/v1/module:8020

After confirmation, please reset the module with following command:

stele:restart

3. Make sure firmware is updated to the latest version.

Application won't work with version 0.6.3. All the above version will update automatcialy. Check if you are not running the initial 0.6.3 version.

Check the current version on the module with following command:

stele:status

You should receive reply. The info that we are looking for is after FV:

860906041740199;AKU:100%(4186),GSM:1(61%/1/1/59600/31041),GPS:p1,f1(18/25),SD:3698,UPT:3,MEM:0,DATA:108749.1,HW:1,FV:1.1.9 19_12_2022

The correct version should be anything above version 0.6.3, if you see your version being 0.6.3 or are unsure if you have new one, you can run following command:

stele:update

4. Check SIM card is operating normally

As a last resort check that SIM card is sending and receiving data by removing it from the module and placing it to your mobile phone. Test sending and receiving of SMS for example to ensure the data are available.
