Re: Regarding Camera Wireless Flash Trigger

Thanks Richard B99 and sirhawkeye64.

I checked the Camtrapper and its one of the features I like to implement i.e. Motion Sensor based Trigger.

I know there are available low cost Wireless Trigger available but my project have some specific needs where I want to implement Flash Control (both Manual and TTL).

However, past days I have more study on TTL and now my understanding is much concrete. Like to introduce some more qus please:

-1. So far I found TTL is SPI communication so I think by reverse engineering its possible to decode the SPI data. But in case of Canon E-TTL and Nikon I-TTL if I am able to decode the control signals then is it permitted to implement in commercial product like Yongnuo or PocketWizard doing?

-2. My aim is to make both Transmitter (Tx) and Receiver (Rx) device where Tx will consist of some Sensors to trigger DSLR shutter in different conditions. In my Tx device I am already implementing Bluetooth 4.0 (BLE) for some other features but will it be good to use BLE for the Flash Communication i.e. adding BLE in Rx as well? Not sure if its the best RF. As for Flash I need to trigger it very fast when Camera Shutter is clicked so delay (wireless transmission latency) needs to be min as possible.

Thanks again.

Regards.
