• Select Settings/Developer Options/USB Debugging

1. Connect the Android device to the computer via USB cable
2. Select "Aways allow from this computer" and OK, when the prompt "Allow USB debugging?" appears on the device

Run the ADB Profiler Wirelessly

1. Ensure the local computer and Android device are on the same network
2. Connect the Android device to the computer via USB cable
3. Set the Android device's ADB listening port
   • adb devices
   • adb tcpip 5555
4. Disconnect the USB cable
5. Identify the Android's IP address
   • Settings/About phone(or tablet)/Status
   • adb_ip=<ip_address>, i.e., adb_ip=10.4.123.244
6. Connect wirelessly to the Android device
   • adb connect $adb_ip
