The projector sees the Bluetooth speaker but does not connect to it. What should I do?
If your Bluetooth speaker has been previously paired with several other devices, it may have trouble initially pairing to the projector. Unpair the Bluetooth speaker from all other devices and then try pairing it again with the projector.
You may also need to reset the pairing setting on the Bluetooth speaker and then verify if it is in pairing mode. It may take several attempts for the pairing to occur.
