In this tutorial we want to show how easy it is to read data from the caranea adapter.

Prerequisite:

  • 12 V power supply either by a normal car with an OBD II connector, a 12V power supply or an OBD II Simulator
  • A caranea adapter either an OBD caranea adapter or a SUB-D caranea adapter
  • A Wi-Fi enabled device like a Smartphone or a Computer

So let's start and see how easy it easy to use the caranea technology

Power up your caranea Adapter with a 12V power device as you learned in the tutorial "How to connect to the caranea adapter".

Read out Speed via OBD II

To read out speed from the caranea adapter, you should use the following request: http://192.168.189.99:9080/vehicle?fields=speed.
If everything works, your should see a result like this:

{ "speed": "80" }

Read out RPM via OBD II

To read out rpm from the caranea adapter, you should use the following request: http://192.168.189.99:9080/vehicle?fields=rpm.
If everything works, your should see a result like this:

{ "rpm": "480" }

Read out Speed and RPM via OBD II

To read out speed and rpm from the caranea adapter at the same time, you should use the following request: http://192.168.189.99:9080/vehicle?fields=speed+rpm.
If everything works, your should see a result like this:

{ "speed": "80", "rpm": "496" }

You can combine vehicle data and adapter data the way you want, so you are pretty flexible to work with the data you want. Learn more about the temporary saving of date in the tutorial "How to define an application configuration".

You see, it is pretty simple to read out OBD II data from the caranea adapter, and the best is, you can define the OBD II Data set for yourself. Check out the tutorial "How to define the OBD II data set".
