I think ssl only works on the web interface, not for GPS tracker ports. Because it would only work on port 443.
Jean, you wrong. Port is not reason, that it use secure connection. For example, SMTP uses port 25, but it cat use TLS protocol after STARTTLS command. Now I search same devices too. I whant to secure connection between trackers and server. Who knows devices, which uses SSL/TLS
I've recently set up traccar (server and android client) and it is working great. I use https for the android client and would like to find an odb2 device that can communicate with the server in a secure way too, does such a device exist?
