Add support for Muse S Anthena device

[Andrey1994]

BLE characteristics are changed and now they match BrainFlow presets perfectly. Instead of one characteristic per channel there is one for all EEG it seems and one for the rest. Its like default and aux presets in BrainFlow:

Current state(updates will be in comments)

• can connect and enable notifications on both chars
• can enable streaming and stop it
• just print all incomming arrays as is for now, parsing and filling brainflow buffers is not done yet
• no idea which preset is needed to enable smth on the second characteristic, tried p21(eeg only) and p1045, dont see any difference between these 2

Incomming data is printed in logs:

One more note: this change in the structure of BLE chars is overall good and makes sense. I will not be surprised if this will be updated for old devices with some fw + app updates

I just want to develop backend to scan and connect with muse S athena and stream EEG signals from it. Can anyone kindly guide me how I can do this? It will be of great help. Thanks

I think this is not yet ready in the opensource community. Streaming data is now possible by brainflow (as above) but data is not yet interpreted to the EEG signal in micro-voltages that you need. If you are ok with offline data processing, paying for the mind monitor app may be the best option. if you are like me, hoping to do real time processing, we have to wait for these guys to update the code. I expect this is happening soon, I think the creators of bluemuse and muselsl are also working on this as we speak.

How were you able to get the raw EEG packets? Im trying with brainflow , but Im getting errors.
