1. Check Bluetooth prerequisites

Android recommends checking that the device supports Bluetooth and that it is enabled before Bluetooth or BLE communication. Start by opening your console’s visible settings and checking Bluetooth status. Do not look for a universal menu path: labels and locations vary by manufacturer and Android version.

For the RG405M, Anbernic’s official specifications list Bluetooth 5.0 and Android 12. This confirms that model’s hardware prerequisites, but does not establish the exact menus on other consoles covered here.

If Bluetooth is off, turn it on and search for the accessory again. If the feature is missing or cannot be enabled, stop here: the sources consulted do not identify a specific cause or support recommending one reset procedure for every model.

2. Try again from a simple starting state

Before changing a saved pairing, turn Bluetooth off and back on. Also check that airplane mode is off if your console has it. Then put the accessory back into pairing mode and search again using the available settings.

Observe the result: if the accessory reappears and connects, a temporary search or accessory state may have been responsible. If it still does not appear, move to the next step instead of repeating the same test indefinitely.

3. Restart the console and accessory

Turn the console and Bluetooth accessory off and back on. After restarting, enable Bluetooth on the console, put the accessory into pairing mode and try again.

If pairing works after restarting, check that it remains connected for a few minutes. If it still fails, note whether the accessory is invisible, visible but unable to pair, or paired before disconnecting: these outcomes point to different parts of the process.

4. Forget the old pairing and start again

If the accessory’s name is already saved but it will not connect, open its entry in Bluetooth settings and use the available option to forget, unpair or remove the pairing. The exact label depends on the model and Android version.

Then put the accessory back into pairing mode and pair it with the console again. If the connection returns, the new pairing resolved the observed symptom; it does not establish the original cause. If it fails, continue checking without immediately concluding that there is a hardware fault.

5. Test the accessory on another device

Try pairing the same accessory with a Bluetooth phone or PC. This recommended test compares accessory behaviour without making further changes to the console.

1. Put the accessory in pairing mode, then search for it on a compatible phone or PC.
2. Record whether it appears, pairs and stays connected.
3. Before returning to the console, end that connection so the other device does not keep the accessory occupied.
4. If possible, then compare with a second compatible accessory known to work on the console.

Failure on several devices points towards the accessory, its pairing mode or compatibility, without proving a fault. If another accessory works on the console, examine the failing combination and its manuals. If several accessories work elsewhere but not on the console, record the model, firmware and displayed messages for manufacturer support. These comparisons alone cannot identify a faulty component.

6. Distinguish system settings from an app

If pairing works in Android settings but fails in an app, first check that app’s permissions. On Android 12 and later, Bluetooth access may appear under Nearby devices. Required permissions depend on the app and its version; follow its documentation and the label actually displayed.

These permissions concern apps. They are not a general requirement for manual pairing through system settings. If failure occurs only in one app, check its requested Bluetooth permissions and compatibility with the installed Android version.

An accessory appearing in an app’s list does not prove that the app has established or maintained a connection. Check its connection indicator and the intended function: sound through headphones or controller input.

7. Reset network settings only as a last resort

Some firmware may offer a network-settings reset, but the sources consulted do not document an identical path or procedure for every model listed here. Use it only if it is clearly identified in your console’s settings and after consulting documentation for that model and Android version.

Before confirming, read the console’s warning carefully and check what data will be removed. Do not accidentally select a full device reset. After a network reset, you may need to pair Bluetooth devices again and reconfigure other connections; if you cannot determine the scope, do not start it.

8. Interpret the result and choose your next action

• Bluetooth was disabled: enable it and pair again.
• The accessory works on another device: test a second accessory on the console to isolate the affected pairing.
• The accessory fails everywhere: check the accessory and its documentation first.
• Manual pairing works but the app does not: examine the app’s permissions and expected behaviour.
• No accessory works on the console: consult the model’s documentation before resetting anything or contacting support.

Do not automatically transfer a menu path, reset procedure or firmware fix from one model to another. Android sources confirm general prerequisites and technical distinctions, but do not provide one identical manufacturer procedure for all consoles covered.

To resume the procedure for your accessory: pair a Bluetooth controller or connect Bluetooth headphones and check the sound. Variant and compatibility qualifications still apply.
