I followed these instructions, and also all the postings related to Bluetooth pairing, but I’m still having a lot of trouble maintaining a successful connection. I wipe out all reference to the device on bluetooth prefs, re-pair, etc as instructed. Then I start muse-io, and it takes a while to recognize the device is there, before pairing.
Starting MuseLab, sometimes I succeed in connecting to muse-io, and I see live data on the eeg channel. But usually after about 7-10 seconds later, it stops. The headset has now disconnected again from muse-io.
Environment: Macbook Pro, OS X 10.9.5.
Incidentally, it pairs up and connects to the “Calm” app quite well, on my iPhone 6. It’s the laptop bluetooth link that flaps on and off constantly.
