Connecting multiple accessories

Hello, I am doint a bit of research, as I will soon be purchasing an iPad. I am finding this site extrememly useful in providing most of the information I need, but I do have one question which I have not seen an answer to: Is it possible to connect more that one device to the bluetooth simultaneous, for example a keyboard and a Braille display? If this is not possible, asre there any other options for connecting things like this to the iPad? Thanks for your help K
