can anyone suggest to me the Chinese manufacture who produce 4G based OBD-2 device with the following specification:

  1. The OBD-2 device should work on the MQTT protocol
  2. The OBD-2 device should monitor all the engine data and also support all US base fuel car
  3. It should also able to send GPS data
