Defining the Identifier and the Hex from CAN Bus to determine Fuel Level.

Jason5 years ago

Hi, my name is Jason.

I am going to open a business in the GPS Tracker industry. Any help would be great.

My current understanding about determining the fuel level is

  1. You have to find the Identifier's fuel level.
  2. You have to configure the protocol on the server side [based on Galileo's video reference]

My question is,

  1. I have GPS Tracker with ADC support,
    a. Do you connect the ADC terminal wire to the fuel sensor wire to determine the fuel level by reading the voltage?
    b. Do you need OBD2 GPS Tracker to download data from the CAN Bus?

  2. How do you configure the protocol on Traccar? Please, if you would please use 1. a. and 1. b. as reference.
    Video reference: at 4:53 on https://www.youtube.com/watch?v=KkVxjou2IA4
    a. Is it viable to configure the protocol per device, so you would only need one model device to server wide range of vehicle.

  3. Could you please recommend me a low cost and reliable GPS Tracker capable to offer low cost fuel level telematics to the end user?

Sincerely,
Jason

Regarding second question. What you have on the video is device configuration, as far as I can tell. It's not Traccar.

Yes, it is Galileo's. My thought's on Galileo is it configures the device protocol from the server side [based on the video reference]

I was wondering, does Traccar do things differently?

Update
I've found a thread about 1. a.

You don't need to configure anything on the server side. Not sure if fuel info is supported for Galileo protocol though.

Thank you.

I understand my mistake. Please excuse my ignorance.

My thoughts now:

  1. Wired GPS Tracker and OBD2 GPS Tracker is a different solution.
    Wired is for low cost vehicle theft prevention (you can hide the GPS Tracker anywhere on the vehicle).
    OBD2 is for advanced AVL systems, it requires configuration for example if you want to be able to read fuel level from the CAN Bus per se every vehicle outside the U.S. region has different protocol used. It can be spotted fairly easily by thief.
  2. There's 2 way to read fuel level, from the CAN Bus and fuel gauge.
    Some Wired GPS Tracker provide ADC support to read the voltage from the vehicle-factory's fuel level sensor.

Please advise me if I am wrong. Thank you.

I don't really have that much experience with hardware side, so I would let someone else answer those questions.
