Bluetooth and downloading time


Could you please answer our earlier question in the link below?



  • I just collected data from a MMS sensor with the settings in the picture for 1 minute and it took ~4 minutes to download in close proximity to my iPhone
    , which seems way too slow. Any thoughts?

  • Yes this is normal.
    While you may have recorded data at say 200Hz and gotten 10 million data points in 1 second, the Bluetooth link can only download data at 100Hz. So to download 10 million data points, it will take 2 seconds.
    The Bluetooth is slower than our sensors! That's why you can't stream data to your phone at sensor speeds higher than 100Hz (and you must log instead).
