DJI FPV Protocol #442

Open al21883 opened 3 years ago

al21883 commented 3 years ago

Since the DJI digital FPV system is being a hit and several pilots are switching their video systems to this one on custom builds. It will be wonderful for a lot of people to have the option to use the built in receiver on the "Air Units" and "Caddx Vista" units.

Maybe, in a few months, it becomes the most common receiver mounted(not used) on quads an FPV machines.

It will be difficult (even if it would be nice) The DJI FPV remote control works in 5.8ghz and, from what I know, no module of the multi-protocol is able to transmit in 5.8Ghz

DJI uses completely different components and tech from common RCs.

al21883 commented 3 years ago

Thanks for your replies. I had read somewhere that the transmitter could work in 2,4Ghz too. I think it could be possible with DJI's collaboration. This time they have put on the market a product oriented to DIY RC people and have integrated open source OSD protocol to it's product.

Thats OSD tho not control, Control needs a specific chipset (Or an SDR) in order to transmit the control signals as the rx is expecting it. I am pretty sure DJI will not release too how there RF system work, it would have to be reverse engineered.

The RF-Signal of DJI FPV is pretty much the same as OcuSync only that they do their frequency hopping within a specific channel. The Downlink is essential for the link to work so at the bare minimum we would need a 20+MHz SDR + fpga + internals from DJI... Yeah - not going to happen.

@pascallanger close this issue maybe?

pascallanger commented 2 years ago

I'm not sure if I should close it since people don't check closed issues and they open new ones. Adding the "Won't do" status was for me a way to show that I'm aware and won't work on it...
