What is the data throughput speed of a Bluetooth connection?
The speed of data that enters and goes through a Bluetooth connection, or throughput, depends on the Bluetooth version of your device – the newer the version, the faster the data transmission. For example, Bluetooth V2.0’s optimum speed is up to 3 Mbits/s, while the Bluetooth  V3.0’s optimum speed is up to 24 Mbits/s. Newer versions are even faster than this.
