As of July 2022, we do not track BT connectivity. For stability tracking, we recommend using breadcrumbs to track normal BLE events and then error logs to track abnormal events.
For example, for performance tracking, you could use moments by starting a moment when the user initiates the connection and ending the moment when the connection takes. That would provide you with a good view of the average performance your users are experiencing and incomplete moments would show you how many users are failing to connect.
If you are interested in us adding support for monitoring Bluetooth connectivity, please let us know by sending us an email to support@embrace.io.
