Seems to be for the kind of Bluetooth module that you are using. I’m trying to find a plguin that will work with something called an RFduino, I’m hoping that this plugin will do the trick!
please can you help me i bought i library of bluetooth but i dont know how can i use it? because i need to make the communciation with bluetooth hc05 in unity using that librery ?
I don't think Unity has built-in support for that, but you might be able to find a plugin for it. Some people have managed to use sockets to communicate with peripheral devices. Others have used Unity Pro to build their applications with native code plugins that can take advantage of various platform features. Don't forget that your scripts can take advantage of anything that's available to your .NET runtime environment. A code library doesn't have to be "part of Unity" to be useful.
