Bluetooth communication through LabVIEW

[Mudit099]

I am trying to communicate my Bluetooth earphone with LabVIEW. I am able to establish communication with my earphone. I am using VIs dedicated for Bluetooth which are there under "Data Communication" in "Protocols". Now I don't have any idea of what kind of command I should give over my Bluetooth device i.e. earphone in order to say play music or audio of a particular ".mp3" file does anyone have any proper literature or an example for your own Bluetooth device(particularly earphones) where you did such communication?

my problem is not about establishing communication with LabVIEW but rather about what should I write in write vis of bluetooth in order to run my audio file on my bluetooth earphones. Its like you have established communication with Modbus device but you don't have information of register and what kind values that register takes. So if you have that kind of literature please give that.

That is the crux about interfacing with devices. And Bluetooth is just like USB not just a simple link where you send a few characters over it (most of the time). Instead the link is binary data and each sort of device (and usually manufacturer) has their own specific bits and bytes that you need to send and receive.

So it’s not just that you could format some (still possibly obscure) string together and send it but that you need to understand the binary protocol down to bits. And while there are common device profiles like for instance for audio earphones, the specifications for them are spread over several standards documents comprising of a few thousands of pages. Unless you or your employer is in the business of manufacturing such earphones, it’s cumbersome to find those standards and even more cumbersome to read them. Understanding them is an even more complicated matter.
