Use the adb connect command to connect multiple Android devices (WIFI way)

Connection Instructions and Steps

In addition to USB connection to Android terminal devices (the USB port on the PC side is limited, and WIFI is more convenient in some cases), it can also be connected by adb connectcommands using the TCP/IP protocol.

  1. Turn on the USB debugging function in the phone settings (some phones can also restrict whether to allow remote debugging, if this option exists, you need to turn it on together).
  2. Connect the mobile phone and PC to the same network (connect to the same WIFI).
  3. Connect the phone to the computer using USB.
  4. Use the adb devicescommand to check the device connection

$ adb devices
List of devices attached
 693298 ff device # Currently connected device 1 
693298 gg device # Currently connected device 2

  1. Use the adb tcpipcommand to specify the tcpip port of the mobile device on the computer side

$ adb -s 693298 ff tcpip 5555 
restarting in TCP mode port:  5555  # enable result

The 5555 port is the default port, and other ports can also be used. -s is the parameter for operating the specified device in [adb] -s 693298ff is specified to perform this operation on the 693298ff device. If only one device is connected, this parameter can be omitted.

  1. Disconnect the USB connection between the phone and the PC
  2. Use the adb connectcommand to connect the phone to the computer

$ adb connect  192.168 . 3.142 : 5555 
connected to 192.168 . 3.142 : 5555  # remote connection result is the ip of your mobile phone after connecting to WIFI. Again, the mobile phone and the computer need to be in the same network environment (as long as the wired network is in a local area network)

  1. Use the adb devicescommand to check the device connection

$ adb devices
List of devices attached
 192.168 .3 .142 : 5555     device   # Remotely connected mobile phone 
693298 gg device # Mobile phone connected via usb

  1. When multiple devices need to be connected, the above operation can be repeated, but the port number needs to be slightly modified and cannot be repeated .

It should be noted that if a mobile phone is connected to the PC through USB and tcpip at the same time, adb devices will recognize 2 devices, but they are actually 2 connection methods of the same mobile phone.

  1. When the device connection is no longer needed, you can use the adb disconnectcommand to disconnect, for example:

$ adb disconnect
