My wife and I ride together each morning on dumb trainers. We both use BLE speed and cadence sensors. I use the mobile app connected to a Windows 10 laptop and she uses direct BLE connection to a Mac Mini. I have a heart monitor, also BLE to the mobile app.
Recently, she bought a VivoActive HR watch and it broadcasts HR to Zwift via an ANT+ dongle on the Mac. If she’s alone, it’s fine. But if I start my HR monitor, her’s does not work.
To begin, I get everything of mine set up and start riding. She opens her pairing screen and selects the VivoActive HR. It sees my HR monitor via ANT+ as well as her VivoActive. She selects her’s but it shows 255 bpm on the screen and never changes as long as my HR monitor is on. When I take mine off, as soon as it stops broadcasting, her HR monitor begins to work correctly.
Is there anything I can do, change, break, etc. so we can both use our HR monitors?
