Recently I have found that my Power and/or cadence sensors are dropped after a couple of minutes riding unless I reboot the Mac before starting Zwift. My current setup is as follows:
- Macbook Pro (2017) with OS Catalina & Ant+ Dongle
- Quarq Power Meter (also provides cadence)
- Wahoo Snap tranier
When I first login to Zwift it sees all sensors - (Power, cadence, trainer, heart rate).
I then start riding (or join a group ride) - the ride starts ok but after a couple of minutes the Cadence & Power ceases. If I reboot the Mac and restart Zwift everything connects again and everything works fine.
It is more frustrating when I am planning to do a group ride - the sensors all remain connected during the “warm up” prior to the ride starting but then drop out after a couple of km. Restariting the Mac & Zwift & rejoining the ride fixes the issue.
I have tried just re-connecting the sensors and re-starting Zwift without a reboot but once the sensors have dropped they will not reconnect.
Has anyone else seen this and are there any known work arounds apart from rebooting the Mac everytime I run Zwift?
Could the issue be that either the Bluetooth or ANT+ stack on the Mac are being left in a bad state after Zwift exits (either by Zwift or a bug in Mac OS).
Further things I could try:
- Connect using Bluetooth instead of Ant+ (or Vice Versa) next time it happens
- Run Xwift complete a session and exit. Then re-start Zwift and see if teh problem is encountered.
Any ideas suggestions greatly appreciated.
