To achieve CD quality (16bit/44.1khz stereo) need 1411.2 kbit/s bandwidth, obviously Bluetooth A2DP cannot allow (Bluetooth 2.0/2.1 + EDR The largest carrier rate is about 2.1mbit/s, minus the protocol header, interference, power dissipation factor influence , the actual maximum transfer rate is approximately 1000bit/s), so the audio data needs to be compressed. We know that the same bit rate, different encoding format compression rate is different, t

The LAN sharing method is not difficult. It is difficult to connect to the Bluetooth LAN, but the ping fails. The packet is sent normally, and the accept packet is increased at a rate of 0 or close to 0. There are obvious signs of different networks. When I first installed the system and drive path, I was able to connect to the Bluetooth shared LAN. But then I couldn't do it. I got it all day yesterday and finally got it again. But honestly, I really don't know why. I will only publicize the st
