About IDC777-DK

I have a question regarding the IDC777-DK module. It was discovered that this module could be used as a Bluetooth headset by connecting to a smartphone. Can this module be programmed separately? If so, are there any SDKs or tools provided? Is there a user guide?
Also, I saw the following picture in the document: Could you please explain how this is possible? Why is my headset connected to only one smartphone? Can I pair other headsets without connecting them to a smartphone?

Hello lilly,

I will let one of the engineers help you with this, as I am not aware of how this is programmed.
Also, do you have a DigiKey part number, as the number IDC777-DK does not go into our system.
