Test OBD iOS App without using vehicle

Question

Currently, I am working on an iOS App using OBD device. How can I test it without using a vehicle.

You will need to create a class that provides simulates the device and provides mock data. — Paulw11, Sep 12 '16 at 07:28

You'll either need to purchase a simulator, which can be upwards of $300-400, or you could setup a bench ECU.

You should be able to find an ECU in a junkyard for $20-40 with the connector then you just need to wire it to an OBD2 port and a 12V for power. No messing around with creating testing classes, you'll be dealing with real world implementations.

You can either, as one commenter suggested, write a class that implements a common device interface and provides mock data, or use a hardware simulator like this one

The problem with iOS is that BT OBD adapters will not work, only BT-LE.

I took the following approach:

OBDSim has a TCP fork that lets it run using a TCP channel (note that this is different from -g Socket - this does not create a TCP channel for communication)
I compiled this fork and it works great. I run it on OS X using obdsim -T 5000 -g Cycle which runs it onTCP port 5000
Next up,there is a fork of node-blueooth-obd package which added an option to make it work over TCP as well. You can find the fork here
Finally, you can use ionic & cordova to use this forked library and communicate with a TCP based OBD simulator - see an example here

This setup is great for testing, and you should be able to swap OBDsim with WiFi ODB adaptors like OBDlink from Scantool
