Good day. Thank you for your question.
Our devices only send data in the codec8/codec8 extended and other codecs. You may refer here for the protocols - https://wiki.teltonika-gps.com/view/Codec
How the server compresses this data to a specific format depends on the server provider. If you would like to see our device RAW data (HEX packets) then you may use our listener which is available in the Teltonika Drive links but you will need to contact your Sales Manager or raise a ticket on VIP Helpdesk.
If you don't have any contacts with our Sales managers, please contact them on our official website https://teltonika-gps.com/ and click on the "Contact Us" button. When you will click, please fill the form and submit it.
Note: as a topic, please choose "Vehicle telematics" or you can send an e-mail with the description of your situation to email@example.com
Thank you for your understanding.
