How to test a controller over Bluetooth

Your controller says it is connected, but a game ignores button presses or the stick seems unresponsive. First check whether the controller is sending input to the computer at all. That separates a Bluetooth or controller problem from a game setting.

The Gamepad Test shows button, stick, and trigger input in your browser. It can confirm that inputs are arriving, but it cannot tell whether the controller is connected over Bluetooth or whether a particular game supports it.

Test the controller over Bluetooth

1. Pair the controller with your computer using its Bluetooth pairing process. Keep it close to the computer, and disconnect it from any console, phone, or other computer it may reconnect to.
2. Open the Gamepad Test. If the controller does not appear right away, press a controller button or move a stick once. Some browsers wait for input before showing a connected gamepad.
3. Press each button one at a time. Check that the matching input changes in the test, then release the button and confirm it returns to its resting state.
4. Move each stick slowly through its full range, including the center and all four directions. Watch for a position that jumps, sticks, or fails to return to the middle.
5. Squeeze each trigger gradually from fully released to fully pressed. A trigger may report a range of values rather than only on or off.
6. Repeat the same checks after moving a few feet away, then near the computer again. This can reveal a weak or inconsistent wireless connection.

For a fair comparison, close games and other apps that may be using the controller. Keep the controller charged, and test it in the same position each time.

What the result means

Every control responds consistently

The computer and browser are receiving the controller's input. If a game still ignores it, focus on that game's controller settings, supported controller types, or control bindings. A browser test cannot confirm that a game recognizes the same controller layout.

Some buttons do not register

If the same button fails repeatedly, the issue may be in the controller, its current mode, or the way the operating system exposes it. Test the button in another browser or on another device before deciding it is physically broken.

A stick moves unevenly or does not center

The test is showing inconsistent stick input. If it happens while the controller is still and repeats after reconnecting, the stick may have drift or a worn sensor. A game may also apply its own dead zone, an area around the center where small movements are ignored.

Inputs stop when you move farther away

The controller is reaching the computer unreliably over Bluetooth. Distance, walls, low battery, and nearby wireless devices can all contribute. If input remains steady close to the computer but drops at your usual seat, the connection range or interference is a likely factor.

The controller does not appear in the test

The browser may not have received a gamepad event, or the operating system may not have connected the controller. Confirm Bluetooth pairing first, then press a controller button with the test page open. Some browsers and mobile devices have limited gamepad support, so repeat the check on a desktop browser if needed.

How to fix Bluetooth controller input

1. Charge the controller. A low battery can cause delayed input or disconnects. Charge it, then test again while sitting close to the computer.
2. Check the controller's connection mode. If it can pair with more than one type of device, set it to the mode intended for a computer and follow the manufacturer's pairing steps. A controller connected to a different device may not send input to this one.
3. Reconnect Bluetooth. On Windows 11, open Settings › Bluetooth & devices › Devices, remove the controller if it is listed but not responding, then pair it again. On macOS, open System Settings › Bluetooth, remove or forget the controller, and pair it again. Menu wording can vary slightly by controller and OS version.
4. Reduce distance and interference. Move the computer and controller into the same room with a clear path between them. Temporarily move other wireless devices away and retest. A USB Bluetooth adapter may also work better in a different port or position.
5. Restart the browser and computer. Close the test page, restart the browser, and reconnect the controller. If input still fails, restart the computer to clear a stuck Bluetooth connection.
6. Check the game's controller settings. If the browser test works but one game does not, enable controller input in that game and review its button bindings. Check whether the game supports your controller model and connection mode.

When the controller may be faulty

Test it over Bluetooth on a second computer or compatible device, and, if possible, test it with a USB cable too. If the same button or stick problem follows the controller across devices, while other controllers work normally, the controller is the likely cause. Check its warranty or arrange a repair. If only Bluetooth fails but wired input works, the fault may be in the controller's wireless hardware rather than its buttons.

What a browser test can and cannot prove

The Gamepad Test checks the inputs the browser receives. It does not measure Bluetooth signal strength directly, identify every controller model, or prove that a game will accept the controller. Bluetooth pairing can appear successful even if the controller is using an incompatible mode, and games can apply their own dead zones or remap controls.

If the test works but a game does not, use the game's own controller settings as the next check. If the same inputs fail in the browser and in multiple games or devices, investigate the controller or Bluetooth connection instead.
