Last few weeks I’ve not been able to use my garmin hrm with zwift - on pairing its continually coming up with ‘no signal’. I’m using zwift on a windows 10 laptop.
I’ve done a bit of research into this and seen there’s the possibility of the Bluetooth signal being stolen by other devices so I’ve already tried switching off garmin edge 520 / forerunner 935 / iPhone 6+ and still the issue persists.
Ive had one occasion amongst this where it paired when I opened my laptop and started the zwift app when not doing any cycling but every other time I get ‘no signal’
Can anyone suggest what is required to isolate the issue and resolve ?
Are you connecting your HRM to Zwift using BT or ANT+?
Just to confirm: you are not using the Companion as BT bridge?
I understand you are able to get HRM reading on your FR935 (using ANT+). Is that so?
Can you try ANT+ connection on you PC?
I would also try shutting down all 2.4GHz sources, such as 2.4GHz WiFi, all BT devices, etc. (and connection your laptop directly to the router, not using WiFi…)
No direct to the laptop alongsite a set of P1 Powertap pedals
Correct.
To try the ANT+ connection to PC I assume I’d need the USB dongle yes?
‘I would also try shutting down all 2.4GHz sources, such as 2.4GHz WiFi, all BT devices, etc. (and connection your laptop directly to the router, not using WiFi…)’
I have no idea what 2.4 GHz sources are. I’ve already tried shutting down everything I’ve ever paired the HRM with and it’s still an issue.
I was working toward the assumption your HRM BT is not working properly - only it’s ANT+ leg is. How about HRM reading using your mobile phone’s Garmin Connect?
There a numerous posts about this bug affecting Garmin and ticker dual HR monitors.
From memory the only way anyone solved their problem was (they were using an iPad) was to do a factory reset of their iPad and load all apps back on. I believe this bug was introduced in the last update and is affecting a lot of people with dual HR trying to use Bluetooth (but maybe not all people).
Since you are on a pc the obvious thing to try would be uninstalling zwift. Ensuring that all folders and files for zwift are actually deleted. And then installing zwift again. The only data you’d lose is custom workouts and 30 day PRs (and if you really care about them there is a way you can back them up).
Use control panel to uninstall the program. Then go to documents and delete the zwift folder. Go to downloads and delete the zwift folder. Search your computer for zwift and have a look at those things.
I’d suggest you send a support ticket then to support and tell them everything. They are back logged so it will take more than a week (from other people’s experience). If you send additional requests/enquires your ticket gets automatically sent to the bottom of the pile.
