Hello Fazin,
Good day. Thank you for your question.
We do have AWS firmware for FMB devices except for FMX6 device. It has TLS + MQTT but can only be used with the AWS platform. In order to obtain this firmware, you may either raise a query on the VIP Helpdesk or contact your Sales Manager. 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
Thank you for your understanding.
Kind regards.
