I think it is btsdio. When I rmmod the driver, I dont see hci0 anymore. So if this is not the correct driver, I need another one. But it seems the correct one is still under developement, correct? > > Please also check with "rfkill list" if the device might be blocked.

There is a sdio driver claiming the bt and uses the same mmc but with #3, while wifi takes #1 and #2. Googling I found that the intel edison board also has a broadcom 43340. I also read BT works on this device. So, there should be a driver for it, right?
