This issue has been resolved.
To address this issue, update your LabQuest 2 to version 2.9.0 or newer.
LabQuest 2 Updates
This information applied to LabQuest 2 only. LabQuest 3 was unaffected.
Due to global parts shortages, some Go Direct sensors were built with different Bluetooth radios that were found to be incompatible with LabQuest 2 units running software version 2.8.9 or older. Affected sensors could not connect to LabQuest 2 via Bluetooth wireless technology. This issue has been resolved with a LabQuest 2 software update (version 2.9.0 or newer).
NOTE: LabQuest 2 units made before August 2013 have a Bluetooth radio that does not work with Go Direct sensors via wireless connection. This hardware issue cannot be resolved with an software update.
For more info, see: How do I know if my LabQuest will work with Go Direct Sensors and Go Wireless devices?
