Python scripts to work with HRV collection and viz from HR belts.

Heart Rate Variability

Scripts in order of usage:

• 01: Simple list ble devices.
  • 01a: Search for a specific ble device.
• 02: Collect the HR and RR and print them to the screen.
• 03: Stream the HR and RR data with LSL.
• 04: Check an XDF file written with the last script.
• 05: Connect to multiple ble devices, and broadcast for each two streams.
• 05a: Search for multiple devices.
• 05b: Connect to multiple devices, no LSL just print.
• 06: A simple GUI for LSL.
• 07: Receive and print LSL data.
• 08: A simple plot from LSL data.
• 09: Larger visualization of different HRV variables.

TODO: Compare time deltas. Compare same subject, multiple devices. Extract ECG from Polar H10. Compare RR to HR, ECG to HR, and ECG to RR.
