Cannot connect to device

Wi-Fi Mode

1. Check Firewall Settings

   Windows Firewall may block inbound connections. Please follow these steps to manually allow the ports:

   1. Press Win+R, type powershell, then hold Ctrl+Shift and click "OK" to run PowerShell as administrator.

   2. Enter the following commands:

      New-NetFirewallRule -DisplayName "MicYou-6000-TCP" -Direction Inbound -LocalPort 6000 -Protocol TCP -Action Allow
      New-NetFirewallRule -DisplayName "MicYou-6001-UDP" -Direction Inbound -LocalPort 6001 -Protocol UDP -Action Allow

      MicYou uses TCP port 6000 (control) and UDP port 6001 (audio data) by default. Change the port numbers if you have configured a different port.

      If no error appears, the operation was successful. Try connecting again.

2. Check if devices are on the same subnet

   • Ensure the Android phone and PC are connected to the same Wi-Fi router.
   • Ensure that AP Isolation or Network Device Isolation features are disabled in router settings (refer to your router's manual).

TIP

Advanced users can try using tools like Nmap or ping to check connectivity.

USB (ADB) Mode

1. Enable Developer Options

   The steps below may vary depending on your device. Please use a search engine to find instructions for your specific device.

   • Find "About phone" in phone settings, tap "Build number" 7 times to enable Developer Options.
   • Enter Developer Options and enable USB debugging.

2. Confirm ADB connection

   ADB tools must be installed on the computer (see Step 1: Download ADB above).

   Run the following command to verify that one and only one device is connected:

   adb devices

   If multiple devices are listed, specify the target device for port forwarding:

   adb -s <device_serial_number> reverse tcp:6000 tcp:6000

   The device serial number can be found in the output of adb devices.

If your Mac has a built-in microphone, the microphone settings will not revert to normal if you haven’t installed switchaudio-osx or if the app exits abnormally.

You need to manually change the setting in “System Settings” / “System Preferences” > ‘Sound’ > “Input” to your device's microphone.

For built-in microphones, they may be named “MacBook Pro Microphone,” “MacBook Air Microphone,” or similar names
