Herelink Dual Ops Setup

I heard the newest update of herelink allows a dual ops mode to use two controllers to control the drone as well as the payload. Is there a manual or setup page outlining the appropriate steps for setup?

Go to Herelink Setting App > Joystick
Select Dual Cont. On your main controller, select MAIN. On vice/backup controller, select the IP of main controller.

I tried turning Dual Cont and main toggle on the main herelink controller paired to the air unit on the drone. On the secondary controller I tried all the IPs as well as the default setting and I am not getting any inputs on the main controller joystick readout or in ardupilot? Do I need to hotspot them how are they communicating over IP between each other?

You need to connect them under the same network. Eg: hotspot/common wifi
