Difference between blluetooth data rate and UART baud rate

[chensx2012]

I am working on high-speed data transfer by bluetooth. As far as I know, the maximal data rate of bluetooth 2.1 EDR is 3 mbps. But the maximal UART baud rate is only 1382400 for the corresponding serial bluetooth module (such as HC-05). I wonder whether it is possible for the baud rate to reach 3 mbps (equal to the data rate) for the bluetooth module, so that I can use it to transfer my data at 3mbps. Any advice would be greatly appreciated.

In any wireless data system, the net throughput is a fraction of the air link "burst" rate. It's due to delays from things like duplexing, error correction, ratio of error correcting bits to data bits, and son on.
In WiFi, a rule of thumb is 60%. Bluetooth with frequency hopping and other causes, may be less yet.
