Hello,
there are lots of heart-rate monitoring apps on android, but I wanted to get real time HR to my linux mint screen, ideally as a graphic line. I found quite sophisticated command how to get readings on my polar hr10 strap to terminal (see screenshot, it produces nice output - every second I get a new line/reading, HR is the first number).
But how to get this numbers from terminal to some graphic form realtime? I guess I have to send the output to file (will the file update realtime?), and then read it from file and somehow show it graphically. Do you have any ideas on how to do this in command line, ideally without too much additional libraries? Or is there a software for this?
Thanks,
Vladimir
