Let's start with the phone. The dlna function of the cool dog is turned on. Click Cool Dog Settings on the computer again, and find dlna to start, in the lower right corner. Then turn on the music player on your phone. After the music is turned on, there will be a dot on it. Click it, and two options will appear. Choose the second one, don't learn that from this machine. Do it. If not, play cool dog on mobile phone and computer, turn off all software and restart. After that, on the mobile phone, there should be a dot in the upper right corner of the music. Just click again and wait for the second one to be your spokesperson's name. That's what I just did.
