A method for Bluetooth communication includes: in Bluetooth communication, allocating bandwidth resources as a first bandwidth resource for communication with a data source device and a second bandwidth resource for communication with a slave device; in the communication with the data source device, receiving and caching data from the data source device; in the communication with the slave device, determining whether the volume of the cached data is less than a first threshold; and if the data volume of the cached data is less than the first threshold, using at least a portion of the second bandwidth resource for the communication with the data source device.
