Conclusion
Alexa Bluetooth connection issues are most commonly caused by devices not being in proper pairing mode, range and interference problems, or conflicts with previously paired devices. By ensuring your Bluetooth device is in discoverable pairing mode, keeping devices within 10 feet of each other, and disconnecting or forgetting old pairings, you can resolve the majority of connection problems.
Remember that Alexa can only maintain one active Bluetooth connection at a time, so always disconnect the current device before attempting to connect a new one. The voice command “Alexa, disconnect Bluetooth” followed by “Alexa, pair Bluetooth device” creates a clean slate for new connections.
For persistent issues, forgetting all previously paired devices through the Alexa app and starting fresh often resolves mysterious connection failures. Reducing interference by moving the Echo away from Wi-Fi routers and other wireless devices, and ensuring both the Echo and Bluetooth device have current firmware, creates the most stable connection environment.
With proper pairing procedures, attention to range and interference, and regular management of paired devices, Alexa’s Bluetooth functionality provides convenient wireless audio streaming for both outputting Alexa content to better speakers and using your Echo as a Bluetooth speaker for phones and tablets.
