@igger Unfortunately, after Charge 6 has been released it came up it can pair with very few apps/machines. The way Fitbit implemented broadcasting doesn't generate the same behaviour as other external HR monitors. Except pairing it to my phone running Strava app, I haven't manage to get it working with any equipment I own (and also the equipment in my gym) and neither with Zwift or Rouvy apps. This is rather dead feature if Fitbit won't implement it correctly.
Best AnswerNo idea how it happened, as the Echo bike's Bluetooth was not turned, but it displayed the HR from the Charge 6 and it was accurate.
Best Answer@igger did you ever figure out what worked here? Trying to accomplish same thing for my echo. Did you connect to any apps on your phone that may have facilitated the connection?
