Does anyone know what the 4 pin port is on the back of the controller? It's between the regular USB and min USB ports.



Sorry if this has been asked before. I did try to search for it...

I asked previously, can-bus port for future expansion

Thanks. Any documentation shared at all? Any info about what data is available on the bus?

I found a great post about the DJI CAN BUS and even how to read some data from it here:

It includes some custom microcontroller code to do the work. Amazing.

You can also buy a hub to connect more than one device here:

There's even a bluetooth module here!

Now, can anyone help me find the protocol documentation for the bluetooth module? This seems like it might be exactly what I need for my project.
