iOS Core Bluetooth Serial Port

Question

Given I have a bluetooth device which returns some serial data - how do I read it using CoreBluetooth?

There is no Characteristics or Services. Just some binary data in known (actually obd ii) format.

Answer 1

I think iOS blocks the access to the serial port over bluetooth.

You might need to buy extra hardware, use WiFi, or jailbreak it.

RS232 for iOS device

Answer 2

Try using roqyOBD if you manage to jailbreak your iPhone. I believe that it creates a TCP server that you can use FuzzyLuke's OBD2Kit and thus read the PID's that are sent from the OBD-II interface to the iPhone.

Let me know how it goes! I myself am tinkering OBD-II with iPhone and am learning just like you.

Answer 3

You probably have a Bluetooth 2.0 or 3.0 device which is not BTLE compliant. CoreBluetooth is an implementation of BTLE, hence you can't use said device on (non-jailbroken) iOS. There are a lot of BTLE compliant devices these days, so better get one of those, if you want to interface with iOS.
