Muse S - AUX electrodes Right and Left

[jamesdgb]

Hi,

I have the Muse S (MS-01) and in the last iOS update of the app we can see that:
"Left and Right Aux for Muse S"
I currently have an electrode from Myndlift for AUX Right.
Would someone have any information about AUX Left, especially how to wire the additional electrode?

Many thanks
James

See here for instructions on making the electrode: viewtopic.php?p=2343#p2343
The Mynclift one likely won't be compatible.

For the Muse S I believe you can use Pin 2 and Pin 4 to get both left and right.

Thanks, that's very useful I will try it.

In addition I am also using BlueMuse (https://github.com/kowalej/BlueMuse) to stream to LSL.
I am trying to update the application so I can access Right Aux and Left Aux with the muse S. In the code I can see a "handle" for right aux:
"273e0007-4c4d-454d-96be-f03bac821358"
Do you know if the left Aux handle is 273e0008-4c4d-454d-96be-f03bac821358 ?

Many thanks

Well looking into muselsl (https://github.com/alexandrebarachant/muse-lsl)
I found that: MUSE_GATT_ATTR_LEFTAUX = '273e0002-4c4d-454d-96be-f03bac821358' # not implemented yet 0x1c-0x1e

I'm pretty sure 2 is left and 7 is right. I think 8 is DRL_REF.

I'm not 100% sure this is correct, but it's my best guess looking at the Bluetooth data streams.
