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.

That's weird. A Bluetooth Low Energy device should have services and characteristic. Are you sure it use Bluetooth Low Energy, or just "classical" Bluetooth? — Larme, May 14 '13 at 08:22
I'm also trying to do the same. However my peripheral isn't a device. It's a Windows program running on Windows 7 which simulates OBD II data through a COM port via BLE. But my iOS app doesn't detect it. — Isuru, Aug 13 '16 at 12:15

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

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

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.

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.
