Why there are two devices when I connect to my phone?

[Septemberlemon]

when I wanna connnect to my phone, I :

first: open wireless debugging on the phone like

second: connect to it with the command

then I saw to devices with adb

what r them or what's the second devices?

I can't reproduce by enabling "Wireless debugging". But you don't need to enable "Wireless debugging" for the second command.

but if I don't enable "Wireless debugging", I had to connect my phone and pc via usb first, that's not convenient

Yes, but only once after each reboot of your Android device, while "wireless debugging" requires a manual action on every connection.

I seldom reboot my phone but reboot my pc everyday because I will close it when I'm sleeping
so if I don't use wireless debugging , I have to use usb once everyday

You don't have to use usb if you reboot your computer, only when you reboot your device.

Just scrcpy --tcpip=YOUR_DEVICE_IP.

Just scrcpy --tcpip=YOUR_DEVICE_IP.

But if I do that, I'll get this:

"由于目标计算机积极拒绝，无法连接。" means "the connection could not be made due to the target computer's positive rejection."

I understand finally!
It's the issue of abd, most people do
1.connect phone and pc via usb
2."abd devices" to look if the connection is ok
3."adb tcpip 5555" to change the port of phone
4."adb connect phone-ip" to connect with tcpip
5.unplug the usb cable
to connect using abd for the first time (only for the first time)

but I prefer to use wireless way because using usb is very inconvenient!
so I've asked chatgpt and it told me things about "Auto-discovery Mechanism"
at the fist time I have this:

then I open(or restart if u have restart the adb) the "wireless debugging" on my phone, and do "adb devices" twice till I got this:

it found the my phone automatically
then I can connect to my phone with scrcpy finally
back to my original issue, the second device is one who was found by the adb itself,
emmm, I think so, and maybe I need a .bat file to do that
