Patent ID: 8155589

Claim:
A method for Bluetooth bandwidth managing comprising: a Bluetooth device establishing a synchronous connection oriented (SCO) channel to connect to a remote device, wherein a TX slot and a RX slot are reserved when the SCO is established; monitoring intensity of a first sound signal which the Bluetooth device received; using the TX slot of the synchronous connection oriented (SCO) channel to transmit the first sound signal to the remote device if the intensity of the first sound signal larger than a first default value; releasing the bandwidth occupied by the TX slot if intensity of the first sound signal smaller than the first default value; monitoring intensity of a second sound signal which the Bluetooth device transmitted; using the RX slot of the synchronous connection oriented (SCO) channel to transmit the second sound signal to the remote device if the intensity of the second sound signal larger than a second default value; and releasing the bandwidth occupied by the RX slot if intensity of the second sound signal smaller than the second default value.
