video streaming over bluetooth

Hi,

If you are using BLE connection, then its hard to stream bit rates above 50-60Kbs. When connected to an iOS device, the BLE device can set a minimum connection interval of 20ms(more likely that iOs choses somewhere around 33ms as CI). With this you can send 50(30 in case iOS choses) CI in a sec. Each connection event could send upto 6 packets with each packet size of 23 Bytes. Thus you get 50x6x23 ~ 69Kbps as best case and most probably get around 30x6x23 ~ 41Kbps as the default bit rate. 

Will your application be able to stream video over this speed? If you are streaming QCIF images at high compression(like MPEG-4/H.264), it may be possible, but again for encoding/decoding video streams you need an processor with dsp/hw accelerator connected to cc2564. Thus the advantage of using a low power device may be lost.

For higher bit rate, it better to use BT/EDR chips or Wifi based solutions.

Hi,

CC2564 has BT/EDR as well. As chip CC256x don't have any restriction. But depends on the stack you are using.

If your stack supports Video Distribution Profile then you should be able to stream video.
