The latest version of the IOS DJI GO App has an interesting feature added/updates. This is called PilotTalk ( previously named Interphone ). There is not much information about this new function and what aircraft it will be supported on.
If I had to guess, it’s a method for dual operators to talk to each other via the smart device being used. Since dual-ops is only fully supported on the Inpsire 2 and upwards professional to enterprise craft, I would think this will be a feature designed for them.
How the PilotTalk feature would be activated is not 100% known,. Probably via a button assigned to the Candence RC and/or a button within the GO App interface.
“Press and hold on the PilotTalk icon, begin speaking, and the voice message will be sent when you release. You can also customize a button of your remote controller to control PilotTalk”
“Please switch to Master mode before enabling PilotTalk feature.”
I will update you when I have more information.
