Abstract

Aspects of the disclosure provide a terminal adapted to transmit audio data via Bluetooth to a device. The terminal includes a controller adapted to detect configuration parameters of the device and optimally determine configuration parameters of the terminal, and a transmission module capable of transmitting a packet of a first packet type based on a first mode of the terminal and a packet of a second packet type based on a second mode of the terminal. The audio data is modulated by a first modulation mode in the first mode and the audio data is modulated by a second modulation mode in the second mode that is more efficient than the first modulation mode. When the device cannot operate in the second mode but can operate in the first mode, the controller causes the transmission module to create a packet of the first packet type containing the audio data.

Claims8

Dependent claims

A terminal adapted to transmit data to a device via a data communications platform, comprising:

circuitry configured to
detect configuration parameters of the device;
and
prepare one of a first packet of a first packet type based on a first mode of the terminal and a second packet of a second packet type based on a second mode of the terminal,
wherein, when the device does not have a second capability to operate in the second mode but has a first capability to operate in the first mode, the circuitry is configured to transmit the first packet of the first packet type containing the data to the device,
when the device has the first capability and the second capability to operate in both the first mode and the second mode, and has a protocol size equal to or smaller than a threshold, the circuitry is configured to transmit to the device the first packet of the first packet type containing the data,
when the device has the first capability and the second capability to operate in both the first mode and the second mode, and has the protocol size larger than the threshold, the circuitry is configured to transmit to the device the second packet of the second packet type containing the data.
