Muse-lsl, latest version at time of writing OS: Ubuntu 16.04 adm 64 bit Bluetooth:Internal Bluetooth of Lenovo T450 pygatt 3.1.

I've been able to stream data to lsl-viewer, but after 2 minutes or when there is a missing sample the stream just stop. With hcidump i can see that the "missing sample" stop the transfer of data from the muse to the bluetooth device.

I've discovered the problem is with Internal Blueooth of Lenovo T450. So i've disabled the internal one and bought a Trust Bluetooth Dongle (chipset CSR8510 ) which is also suggested by muse http://developer.choosemuse.com/hardware-firmware/bluetooth-connectivity Now it works just fine, no missing packets and no timeouts. I've tried both under linux with lsl viewer and openvibe and under windows with Bluemuse.
