Ardupilot telemetry to a fifo pipe (wifibroadcast)

Hi all,

I am using the latest March Emlid image on my Rpi3 copter. I am working on getting wifibroadcast to send both camera data and telemetry data using the fifo scheme explained here:

Does anyone know if Ardupilot’s output scheme allows a fifo as one of the telemetry streams? such as “-A /tmp/fifo”? Or do I need to pipe to MavProxy and then send it to the fifo with that? I would prefer to remove the hop if I can.
