I'm working on a BLE project and getting a couple of different error codes from writeDescriptor(), depending on what I try to modify. Where can I look up what these are supposed to mean? I'm hoping something like this:

I know I could probably search the codes themselves and get an answer, but I would rather be able to look up any other code that I get in the future as well, even if no one has asked a question about it.

Unfortunately, there is no such list. We present the codes as the underlying native platform (Android / iOS) delivers them, and they do not list their error codes.

Well, that's a shame. Thanks anyway. Knowing that they are platform-dependent does shed a little light on the situation.
