webcam bluetooth nokia
Basically I think that there are 2 problems
Firstly -> Not enough bandwidth (maybe)
let's assume the following.
BT Dongle with BT spec. 1.1 (no EDR BT)
Webcam resolution 640x480
Colour Depth : 32bits / pixel
Frame rate : 24 frames/second
thus (640)*(480)*(4)*(24) = 29.49 Mbit / second and the Bluetooth only provides max 738kbps (or 783kbps) either way the required data rate is not obtainable via bluetooth.
Secondly -> USB devices needs to connect to a usb host.
Most of the USB MCUs around will only act as a slave and thus cannot opperate as a host device. As such the USB webcam will not interface directly with the MCU although there are some work arounds (this is very difficult to do however)
