Hi, when haven’t tested this with the bluetooth module. However, it supports a baud rate of 115200 BPS normally. But, you can command the module to run at different baud rates. We’re not sure what the maximum value is. JPG images at 320x240 are going to take up about 15KB a piece… so, expect about 1 FPS with bluetooth speeds at 115200 BPS.
If you want faster streaming us WiFi, lower the resolution, or use a faster baud rate.
As for documentation on how to do this… we don’t have that right now. Do you have one of the firesale boards? If so, then basically all you need to do is call the compress() function on an image to get a jpg version of the image. Once you have that you can pass that image to a serial object to be sent.
