For investigation, you can download and run the Microsoft's Bluetooth Low Energy sample and see whether subscribing works there. If the demo works, it should be fixable in this repo.

Did you already try subscribing with another platform/program?

I was able to subscribe in Microsoft's sample, but I have the same error in Unity

Does this mean in Microsoft's sample the subscription failed with the same error?

I had problem in Unity (The attribute cannot be written), then I've checked Microsoft's sample and everything was working there and after that for some reason error in Unity disappeared. However I still cannot get characteristc values from some BT devices.
