Hello, could someone tell me how to Mirror BT7 screen on Android TV which supports Miracast technology ?
Windows see it as DVR device but not as Wireless Display. Other home devices can to connect and send display without problems.

And related question, -  Can be BT7 used as Miracast receiver ? Also did meny experiments , but other devices unable to dectect it. :(

Thanks
