Wireless Non-Midi

[Bellows]

I am looking for a commercial product, i.e. wireless-receiver pair, that transmits raw digital pulse data. An accordion controller I was attempting to convert to wireless, i.e. Millennium, is not midi. While midi is present coming out of the module, the midi protocol is apparently not followed inside the accordion controller chassis itself. But, if there is a n affordable commercial wireless system that will transmit the raw data from inside the accordion (I have identified the location), I would use it to transmit that data to the module.
Comments, ideas, discussion appreciated.
