Can someone please confirm or correct my understanding about making a connection with BT? As I understand it, for two devices to be able to connect they must both have the same Service UUID (and Service Class UUID). Say, for example, a BT keyboard. Keyboards are usually handled under the HID group, so the keyboard must advertise that it supports HID and a keyboard. Likewise, on the other side of the connection, the other device needs to also have a identical UUID so that the two devices know that they can 'talk' on the same "port". I presume there's no way around this requirement if the device that you want to connect the keyboard to does not advertise that capability...

The keyboard is the HID Device. I'm not sure if there's a clear client/server distinction with HID. Our BTstack Bluetooth Stack (http://btstack.org) also runs on Linux with a USB Bluetooth dongle (port/libusb) and has an HID Keyboard example as well. This works with iOS devices, too. Please checkout out the documentation and give it a try. You may post on the BTstack Mailing list if you have problems getting it to work.

I have been trying to accomplish this using a program called HIDClient which can be found here: I'm developing on a Linux machine (Ubuntu 16.04 LTS) with a USB BT dongle as my test bed. Today, it dawned on me that perhaps that was because I wasn't emulating the right type of device (client / server). Someone mentioned to me that they believed that the iOS devices are _either_ clients or servers but they could not remember which. I've spent the better part of a day reading through Apple documents online in hopes of finding something that would state either client or server definitively, but I've not come across anything. I am not at all familiar with Apple products, and I'm told that I don't need to be to make this project work. Generally speaking, I find it difficult to believe that Apple products are either a client or a server. My understanding of the client server relationship is that the server initiates the connection between two BT devices. The clients are responsible for replying to that request for a connection, and so forth... for example, a BT keyboard would be connected by a iOS device first 'discovering' it then the user of the iOS device 'pairing' the keyboard to the device. In this case, the iOS device is a server. Conversely, if you have a MacBook and want to pull data off your iPad, you'd initiate the connection from the Mac to the iPad, which means the Mac is in a server role. I'm sure that someone out there can tell me where I've gone wrong or what I'm misunderstanding. I don't think this is just macOS based...

In theory, you could just call -[BluetoothManager pairedDevices] (https://github.com/nst/iOS-Runtime-Headers/blob/master/PrivateFrameworks/Bl… <https://github.com/nst/iOS-Runtime-Headers/blob/master/PrivateFrameworks/Bl…>) of the private BluetoothManager framework. However, it would only work if you sign your app with some com.apple.BTServer.* entitlements (see Preferences.app for comparison), which you can only do when you deploy to a device with a Jailbreak. Also, no app in the App Store should have these Entitlements, so no app should be able to get this list on a recent iOS version. Why do you need to get this list?
