Using half duplex, that is sending then recieving quickly makes it feel like you are sending and recieving at the same time but you are not.
Imagin send for 10ms and recieve for 10ms and you think it is doing it at the same time butit is not.

Sending video use a specific video transmitter notthearduino, it is not fast enough.


aha ok then yes your right
so about the video transmitter i will do search for but do you may know some module that is world wide and might find it anywhere and not expensive ? and for the camera can i still use the ov7670 with fifo can still be for the job ? does the cam matters or not ?

Hi Guys,
You may take a look at this project http://www.arducam.com
They use 115200bps to transfer video http://www.arducam.com/arducam-bluetooth-module-wireless-image-system/
If you can port it to 2Mbps with NRF24L01+, I think it will be much fast than now achieved.

I haven't read the other posts, this might have already been mentioned. The APC220 is what I am going to use for my quadcopter. 433MHz, 1Km range, Serial transmitter and receiver. I picked mine up for $30.00.

i saw this one still not fast enough,
as far as i know from answers i should not use arduino for video transfer, so how do i program theTX RX module ?!!
