PPG Information HRV - Muse-2

[Emjayoh]

Hi,

I am trying to find the HRV Data. I have Muse 2. I tapped 10 times to enable algorithms. But don't see any column in the CSV.

What am I missing.

Thanks

Mike

After enabling the setting and you will see the data in the Accelerometer/Gyro page and also in the recorded and streamed data, but you need to disconnect and re-connect the Muse the first time you enable the setting.

Hi thanks,

I have enabled. Why is this process to obfuscated?

I have disconnected, but does that mean from Bluetooth? Or just restart the app?

I don't see the data, just XYZ.

I made this video/loom to illustrate my experience:

And what does PPG stand for?

[James]

PPG stands for Photoplethysmography.

Thanks James, any more clarity on my experience? I can't seem to find the data. Are there screenshots of what I should be seeing?

After you tap 10 times, did you get the popup saying that Algorithms are enabled? If not, maybe you were not tapping the right place. You need to tap "Mind Monitor" in Settings and when you do, you'll get a message flashing with a count 10, 9 , 8 etc then Enabled/Disabled.

Then disconnect and reconnect your Muse and you will see the heartrate on this screen as below.
When you can see it here, then you know it'll also be in the data streams:

Hi,

Thanks for your response.

Yes I did do exactly that. I see the notice. I disconnect by turning off the app and restarting. Or o I have to complete unpair from bluetooth? Thank for the image. I do not see pulse.

Did you see the video Loom that shows. you what I am doing.

Thank you for the video. I'm afraid that you do not have a Muse 2, you have a 2016 Muse which is model number MU02. as it's the 2nd variant.

The 2016 Muse MU02 does not have a PPG sensor, which is why you're not seeing the PPG data, sorry!

For reference the Muse 2 is model number MU03. You can see all the model numbers here: https://mind-monitor.com/FAQ.php#Compatibility
