Hello,
Thank you for your question. Since MQTT is not included in base firmware yet, I recommend to reach out to us on VIP Helpdesk so we can discuss the steps of configuration with you. You may contact your regional Sales Manager/Distributor. 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 info@teltonika.lt
Regards
