is discovery required when pairing with mac address? about bluetoothdevicepairing HOT 6 CLOSED

@AryanRai ,
I have asked the same question before but didn't get any answer:
https://stackoverflow.com/questions/62502414/how-to-connect-to-the-paired-audio-bluetooth-device-using-windows-uwp-api
The problem is also that not all devices support a notion of "connect". It is a big mess.
The best what I could find is this answer:
https://superuser.com/a/1427538/1182474
It proposes to use a special utility to manually enable every service of your device. But you need to know upfront what services this device exposes. There is no way to just say "connect to everything". Also the proposed in the answer btutils doesn't support Bluetooth Low Energy.

Hello @AryanRai,

Thank you for the interest in my utility.
It is important to know that BluetoothDevicePairing uses Windows.Devices.Enumeration API and therefore is limited by what this API provides.

As far as i know discovery isn't required while connecting with mac address directly.

Given what I said above it is important that it is not only possible in general but also that it is possible using the abovementioned API.
However, I have checked the API and indeed I think there is hope, the following code
var device = Windows.Devices.Enumeration.DeviceInformation.CreateFromIdAsync("<Bluetooth or BluetoothLe> and <mac address>").GetAwaiter().GetResult()
should give me a device class which has Pairing functionality.

Ok. Let me try to check that. If it works I will add it to the program. I don't know when I will have time though. I hope I will be able to do it this weekend. Please be patient.

Also the code which you use "BluetoothDevicePairing.exe pair --mac 12:34:56:78:9A:BC -discovery-time 1 unfortunately doesn't work reliably because 1 second is not enough to discover the device, you can easily get an error like "Pairing failed, device discovering hasn't discovered a device with this mac address". But I understand that you don't have any other choice.

Yea I read about it on StackOverflow, I will try forking and modifying the code and maybe issue a pull req if any success.

Take your time and thanks for your reply. 👍

@AryanRai ,

I have created a new release. Now pairing and unpairing using mac address is much faster. I have used the strategy I have described in my previous message. Now it doesn't need to waste time discovering devices.

Could you please test that it works?

from bluetoothdevicepairing.

Yes i have tested and it indeed does work. Thankyou👍. I have one more question, if my device is already paired i am supposed to disconnect it before running the connect command, is there a better way to just "connect" an "already paired device" (same for disconnect without unpairing)?

Yea I had already taken a look at bt command line tools before looking at your project and hav seen this thread but somehow bt cl tools just didn't suit my project in 2 ways. Firstly, it was quite unreliable on my pc and the other reason was it cannot be freely distributed as-in i cannot use it on a GitHub project. Anyways thanks a lot for all your help. If u ever do find a working solution to this please do let me know. For now I'm still gonna be using your project. For now I'd be closing this issue
