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. Best Matthias

That is encouraging! Thanks!

I'm new to BT, and new to Apple, so please forgive any flubs below.

I am working on a project that is going to look like a BT keyboard to iOS devices.

I have been trying to accomplish this using a program called HIDClient which can be found here:

https://anselm.hoffmeister.be/computer/hidclient/index.html.en <https://anselm.hoffmeister.be/computer/hidclient/index.html.en>

I'm developing on a Linux machine (Ubuntu 16.04 LTS) with a USB BT dongle as my test bed.

I've not been able to successfully connect _any_ devices to the program.

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.

Thanks in advance, Chip Wachob

I don't think this is just macOS based... I've had help in the past for iOS as well

After I went and signed up for this list I realized that it was Mac OS based.

Can anyone point me towards a iOS list where I can request assistance?

Thanks,
