A different HR app (https://github.com/jlennox/HeartRate) works fine.

Happy to troubleshoot more if you point me in the right direction.

Hi, atm i don't have the dev environment installed as recently i had to reinstall Windows, so i can't help in much detail.

The only suggestion i can give is to be sure to properly pair the Bluethooth device from Windows settings BEFORE attempting to use it from Cardia.

BTW, thanks for pointing out another working implementation, i might look at it to see if is possible to improve device connection.

If the other device wasn't paired before, I wouldn't have been able to use it with the other app.

• Tried in the other app, works.
• Tried in Cardia, get the error above.
• Still shows as paired in Windows devices.
