Sdk ultrasonic screen projection settings

The conference room equipment currently has the ultrasonic screen projection setting turned on. During the process of using the sdk for screen projection (TryWithPairingCode), even if the input is not the current conference room equipment’s screencasting code or the wrong screencasting code, you can directly cast the screen. After investigation, it was found that the ultrasonic connection was projected to the screen.

The main questions are:

  1. Does the sdk have any interface related to ultrasonic connection?
  2. If there is no relevant interface, whether the client can set the ultrasonic connection not to be performed automatically
