I am trying to write an App in order to read data from an OBDII port via bluetooth. Now that I have recieved my ELM327 bluetooth dongle I am trying to simply connect using the example BluetoothChat application from the developers webpage. I plan on using this as a template for my connection code. I cannot connect using this application, but I can with the ELM327 app as well as Torque. Does anyone have any suggestions or experience with connecting to the ELM327?

I was working with same project and completed successfully, but I spend a lots of time for exploring thing related to OBD-2 connectivity with Head Unit and Mobile as well. That's why I made a library with sample for the same that t reads standard PIDs from OBD-2, like speed, rpm, maf, manifold intake pressure, manifold intake temperature etc, and based on these values we calculate following parameter as well.

Distance Traveled
Idle Time
Driving Time
Max Speed in one Trip
Max RPM
Idling Fuel Consumtion
Driving Fuel Consumtion
Instant Fuel Consumtion
Rapid Acceleration Times (How many times speed increases very fast)
Rapid Declaration Times (How many time emergency brake is used)

you can refer below library with sample app:

ELM327 is a standard OBD-II tool, you may properly need some modifications work

Why is this even remotely considered a solution? It solves nothing.
