Hey everyone!

So I’m building a receiver module that packs in my TBS Crossfire receiver and attaches to my camera gimbal, which allows the camera operator to move the camera.

For camera control and video transmission, we have a raspberry pi zero w and video transmitter mounted in a different location from the receiver right below the camera. Now just to clarify I can’t move the receiver up to where the pi zero is, because the receiver is controlling the gimbal via some data pins lower on the gimbal.

Anyways, I’d like to send sbus signals to the raspberry pi over Bluetooth so I don’t need to worry about cables getting tangled. Does anyone know of a Bluetooth transmitter board capable of sending the raw sbus data over to the raspberry pi so I can trigger commands?

About the SBUS protocol there is plenty to find.

I would sugest to take a look at the Xbee modules, they do support a so called transparant signal option (what you put in will come out). Not sure if a 2 way communication with SBUS is needed just to controll some servo's otherewise you can also go for the PPM signal.

Thanks for the reply, I'll have to check out those XBees, sounds like they would do the trick. As far as switching to PPM, the gimbal is a DJI and they only support control through SBUS right now per their firmware on the gimbal. I really wish they would open up the ability to use the internal USB bus that they have in the gimbal. It has 3 USB ports on the camera arm used for camera start/stop and for powering their raveneye wifi video transmission, but it seems we are locked out of pushing any sort of signal through those USB ports. If I could, this build would be a million times simpler... Just pump in SBUS to the pins on the gimbal handle and send the unused ones through the built in USB up to where the camera sits.
