How to Keep ADB Connected Over Phone Hotspot (Automatic Reconnect)

How to Keep ADB Connected Over Your Phone Hotspot

This is a simple, step-by-step guide to keep your ADB connection over a phone hotspot using Windows. No CSS or JavaScript is used.

Step 1: Prerequisites

• Windows PC with ADB installed (part of Android Platform Tools).
• Phone with USB debugging enabled in Developer Options.
• Phone and PC connected to the same hotspot network.

Step 2: Enable ADB over Wi-Fi (Temporary)

Connect your phone to PC via USB and open Command Prompt or PowerShell, then run:

adb devices
adb tcpip 5555
adb shell ip route  # optional, shows phone IP
  

After this, you can unplug the USB cable.

Step 3: Connect over Wi-Fi

Run the following command with your phone's IP:

adb connect <phone-ip>:5555
adb devices  # to check connection
  

You should see your device listed as connected over Wi-Fi.

Step 4: Automatic Reconnect Script

To auto-reconnect whenever your hotspot is active, save the following as adb-autoconnect.ps1:

$port = 5555
$subnet = "192.168.43"  # change if your hotspot uses a different subnet

function Try-Connect([string]$ip) {
    $addr = "$ip`:$port"
    $devices = & adb devices 2>&1
    if ($devices -match [regex]::Escape($addr) + "\s+device") { return $true }

    if (Test-Connection -ComputerName $ip -Count 1 -Quiet -ErrorAction SilentlyContinue) {
        Write-Host "Trying adb connect $addr"
        & adb connect $addr | ForEach-Object { Write-Host $_ }
        Start-Sleep -Seconds 2
        $devices = & adb devices 2>&1
        if ($devices -match [regex]::Escape($addr) + "\s+device") { return $true }
    }
    return $false
}

Write-Host "Starting ADB auto-connect"
while ($true) {
    for ($i=1; $i -le 254; $i++) {
        $ip = "$subnet.$i"
        if (Try-Connect $ip) { Write-Host "Connected to $ip:$port"; break 2 }
    }
    Write-Host "No device found. Retrying in 8 seconds..."
    Start-Sleep -Seconds 8
}
  

Step 5: Run the Script

1. Open PowerShell as your user.
2. Enable local scripts: Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned -Force
3. Run the script: .\adb-autoconnect.ps1

Step 6: Optional — Run at Windows Login

Create a shortcut to PowerShell with this target:

powershell.exe -NoProfile -ExecutionPolicy Bypass -File "C:\path\to\adb-autoconnect.ps1"

Place it in the Startup folder or use Task Scheduler to run automatically at login.

Security Tips

• Keep your hotspot password-protected.
• Use adb disconnect <ip>:5555 when done or reboot phone to close TCP listener.
• If your phone supports Wireless Debugging (Android 11+/MIUI 12+), consider pairing method for secure connection.

Troubleshooting

• If adb connect fails, ensure both devices are on the same subnet and TCP/IP ADB was enabled at least once via USB.
• Use adb kill-server and adb start-server if connection issues persist.
