Enable control by default

[blue-j]

If control is not enabled, many arguments don't work, including setting the presets necessary to allow PPG signal transmission, for example. I see no problem with enabling control always.

Hello, Thanks for the commit. with your change, streaming stops after about 5 secs after it starts in MacOS, default preset.
muselsl stream -p
Should I change preset for PPG streaming or PPG/ACC/GYRO combination?

[blue-j]

Yes, I recommend changing to preset 61, which will work for most people immediately. It would not support the aux electrodes, but I think including them by default for most people is confusing.

I rewrote the preset function actually and could share that code as well. I can't recall if the base code actually works for setting presets.

@blue-j
Strangely, I experience unexpected disconnect issue when EEG+PPG recording with preset 61 in Muse S. Is there any preset explanation for sensors configuration(s)?

[blue-j]

I've attached documentation about the presets, in case 61 is not desirable as default:

muse_presets.txt

and here is my fork of the preset function, if it works for you, i would be happy to contribute it.

def select_preset(self, preset="p61"):
    """Set preset for headset configuration
    PRESET 61
    4 CH, 12-bit @ 256 Hz, 52 Hz accelerometer/gyro, 0.1 Hz battery, 32 Hz DRL/REF,
    PPG @ 64 Hz, THERMISTOR @ 16 Hz
    Availability: Muse S 2019, Muse S 2021 (Gen 2)
    """
    try:
        logger.info(f"Selecting preset: {preset}")
        self._write_cmd_str(preset)

    except Exception as e:
        logger.error(
            f"Unexpected error attempting to set preset p{preset}: {e}",
            exc_info=True,
        )

@blue-j Thanks so much! It clearly resolved my questions. I will try with actual device then update : )

Thank you for sharing the details about the presets. I have passed the past hour trying to understand why the PPG stream was not working and now I finally I have found the magic 61 preset thanks to you :)
