I recently purchased a new Muse headband (version 2016), who is rather picky on Bluetooth connectivity. For example, Muse headband (version 2014) is able to connect my cell phone Moto E with Android 6.0. However, Muse headband (version 2016) won’t. Because of this, I spent hundreds dollars to purchase the tablet Nvidia shield K1.
Nvidia shield K1 is able to connect Muse headband (version 2016) ONLY if the GPS of the tablet is turned on. Before signing my account in the Muse app (version 3.0.103), the app asks me for the permission of accessing my file storage and GPS. If I refuse the app to access my GPS, then the app would not allow me to sign my account. And if I agree the app to access my GPS but the GPS function on the tablet is turned off, then Nvidia shield K1 is unable to connect Muse through Bluetooth.
I am not sure why Muse (version 2016) app wants to access my GPS. This did not happen for Muse (version 2014).
