I want to develop an app which will communicate with devices via bluetooth. I am not able to find any tutorial to help me with this. I don't mean bluetooth 4.0 LE but classic bluetooth. All I have found is CoreBluetooth framework but I think this is only for bluetooth LE. I have found also something like IOBluetooth and IOBluetoothUI but I am not sure if it is for Mac OS or for iOS. But still can't find any tutorial or something to help me understand whole process (discovering, establish connection, communication,...). Can you help me with this?

Using a Bluetooth connection, you can use third-party devices such as wireless keyboards, headphones, speakers, car kits, game controllers, and more with iPhone. Note: iPhone must be within about 33 feet (10 meters) of the Bluetooth device.
Make sure that your Bluetooth accessory and iOS or iPadOS device are close to each other. Turn your Bluetooth accessory off and back on again. Make sure that your Bluetooth accessory is on and fully charged or connected to power. If your accessory uses batteries, see if they need to be replaced.
Bluetooth is a wireless technology that allows you to communicate or connect with various devices through radio waves. When your iPhone is within 33 feet of a connected Bluetooth device, you can use Bluetooth on your iPhone to transfer tons of files, images, and more between the two devices.
