Android wireless debugging on multiple devices
adb tcpip &lt;port&gt; doesn't restart the adb daemon in your PC but in  Android and binds it to listen to that specific  port. You can always connect multiple devices in wireless mode. 

Follow these steps:


Plug first device and restart adbd in tcpip mode using adb tcpip &lt;port&gt;.
Connect to first device using adb connect &lt;host&gt;:&lt;port&gt;.
Unplug first device, plug second device and restart adbd in tcpip mode using adb -s &lt;serial&gt; tcpip &lt;port&gt;.
Connect to second device using adb connect &lt;host&gt;:&lt;port&gt;.


You may now unplug the second device. If you execute adb devices you would see both the devices connected in wireless mode. Whenever you intend to do any operation on any of the device, supply identifier using -s.
