Users that have build 54 for the Chrome OS, should update to version 54.0.2840.101 or above. The version Chromebook OS just prior to this build had created a conflict with the use of the PS-3500 Bluetooth Adapter for use with the wireless sensors and the Chromebook. If your Chromebook has not already been updated to version 54.0.2840.101, updating to this version of later should resolve the connectivity issues.
