Max Data Rate of Bluetooth with Microcontroller

[feiutm9898]

I am seeking the information about the effective data rate can be archive by the bluetooth with 8-bit microcontroller.

Let say we are using the ATMEGA64L with 4 kbytes RAM. Usually what is the highest data rate that we can archive?

Anyone have this experience and knowlede to measure it?

Data rate will be controlled by your baud rate, if you will be using an RS232 Connectted bluetooth dongle, therefore you can check the manual of that dongle what is the maximum baud rate it can handle, on the microcontroller side, you will be limited on the oscillator frequency you will using, check your datasheet also what is the maximum supported baud rate of every osc used.

It depends on the interface between the microcontroller and the bt device, so if the interface to bluetooth (bt) is slower than 721kbps, then this interface is not very effective to use. Most Bt devices are having serial interface and are capable of supporting high baud rates .
