But I observed a little problem: The connection with Muse 2 stops at unpredictable intervals after start. I don't know if the Muse 2 device itself is causing the problem or something else. These intervals can sometimes last up to 60+ minutes or just a few seconds. This also happens with the muse.bpd example downloaded from your website. After loosing connection and turning off the Muse 2 device with its button, console shows this message: ACK error code=34304 for: [00 03 04 06 | 00 86 01] Robert

Here is the whole console text: ***************** BioEra 4.202 is started ***************** Loading design: C:\Program Files (x86)\BioEraPro\design\muse.bpd on Windows Connection problem: Incompatible pipes: can't connect pipe [name=Status, id=1642, type=Type: OBJECT, elem=Muse(1259)] type Type: OBJECT in elem:Muse(1259) to: [name=In6, id=1656, type=Type: FLOAT, elem=Polygraph(1395)] type Type: FLOAT in elem:Polygraph(1395) Discovered Muse MAC=0055dab5b89b Muse(1259) Warning: Received secondary connection confirmation, ignoring ACK error code=34304 for: [00 03 04 06 | 00 86 01]

It looks promising with my Muse S, but I don't know if this will help with Muse 2 as well. There should be no ACK error this time (probably), so watch the data streaming. If this happens again, try to change a preset.

Nothing visible on the polygraph. The panel shows ?Streaming?, Battery 0.0, SPS 0. After starting BE the device LED?s indicate connection then immediatly turn off and all together start blinking. The same behavior with all presets. ACK error doesn?t appear any more but this : "Main design stop with delay - MainActionHandler"
