Anker PowerConf series speakerphones (PowerConf, PowerConf+, PowerConf S3 and PowerConf S500) support Bluetooth connections as long as the secondary device has a built-in Bluetooth feature. If pairing fails, try the following:

1. Update the speakerphone to the latest firmware.

2. Reset PowerConf.

3. Delete the Bluetooth pairing history on the connected devices.

4. Restart the secondary device and pair it with your speakerphone again.
