Help in certificate my product

I plan made certificate my product called EB01 for apple. I have a trouble with grouping EB01 in to one of categories from Accessory Interface Specification. EB01 is a bluetooth module (precisly BM64 from Microchip) that enables send music and custom data beetwen phone and amplifiers (EB01 is a plug and play extension pcb to our amplifers). So the input to EB01 is a bluetooth connection, and output is digital data with music and custom raw data (like uart). We plan to desging app for iphone to control our amplifers by this custom data. From above descriptive what device in Accessory Interface Specificationi can assign to my device? BM64 also supprot iap protocol.
