Wi-Fi Direct/Screen mirroring supported device cannot connect to BRAVIA, how to confirm the permission of the device?

Please check the following.

• Wireless devices, such as a router, cordless phone, wireless TV receiver, radio, wireless camera, Bluetooth device, or microwave, emit strong radio waves that may disrupt Wi-Fi Direct performance.
  We recommend these wireless devices be placed far from the TV and mobile phone while performing Wi-Fi Direct.
  
• Since the frequency of 2.4GHz has a lot of interference and noisy environment, packet collision will sometimes occur. Even though we have implemented noise-reducing countermeasure to improve the image quality, our TV software could not guarantee that there is no packet loss during transmissions.
  
• Please try to turn the TV to Off then to On with the remote control to recover.
  
• Please confirm the permission status on Show Device List / Delete.
  If permission is Decline, please delete the registered device from the list and then register it again.
