can anyone suggest to me the Chinese manufacture who produce 4G based OBD-2 device with the following specification:
- The OBD-2 device should work on the MQTT protocol
- The OBD-2 device should monitor all the engine data and also support all US base fuel car
- It should also able to send GPS data
I have also researched by myself, but most of the manufacture offers TCP/IP protocol based OBD-2 device, but I need MQTT base can anyone recommend me the device or the manufacture who has this kind of product.
