These wireless protocols, have many versions (variants) and 
nuances via the prticular hardware that is used. Some light 
reading might better postion you?

I would think that there should be some open-source Bluetooth packet
sniffers that may help diagnose the problem.

I was able to find :

MAC Address Prefix      Manufacturer
001103  kawamura electric inc.


using the MAC address. Perhaps an email to their tech support
descriping your problems might help?

I suggest you dissect the packets and hardware and look for the issue
to your problem. Can you move the BT device to a winblozs box and 
see if it works? Amplifiers die all the time, particularly if they
are overheated or fed noisy power......

could be hardware or software related..... dissect the pieces,

HTH,
good_hunting!
