Bluetooth on the Nitro V 15 fails in two ways in the Acer Community threads: devices that will not pair or keep disconnecting, and a Bluetooth adapter that has vanished from Device Manager. If the adapter is gone, even with hidden devices shown, the driver has been lost, often after a crash or a Windows update, and the cure is to reinstall the Bluetooth driver from Acer's support page for your model. If the adapter shows but misbehaves, owners disabled and re-enabled it, or uninstalled the adapter, shut down and let Windows reinstall it on the next start.
Check that the Bluetooth Support Service and its companions are set to Automatic and running in services.msc. For a headset that connects but sounds poor, remember that Bluetooth and Wi-Fi share a radio on many laptops, so a congested 2.4 GHz network can cause stutter. Before reinstalling anything, check whether Airplane mode is on and whether Bluetooth is switched on in the quick settings, since a surprising number of missing Bluetooth reports are simply an off switch. Then try the headset on a phone to make sure the headset is not the thing that has failed.

Model-specific
What is true of this model and not of its siblings
- Hidden devices
- Show hidden devices before concluding the adapter is gone.
- A shared radio
- Bluetooth and Wi-Fi often share a card, so one can affect the other.
- Keep the BIOS current
- Acer's BIOS updates occasionally fix radio problems on the Nitro, so install the latest before swapping parts.
- Cold boot test
- Shut the laptop down completely, not restart, since Windows fast start can keep a stuck adapter from resetting.
- Wi-Fi and Bluetooth share a card
- If Wi-Fi also fails, the combined card or its driver is at fault, and a single driver install may cure both.
Stop boundary
When this stops being a self-service repair
- !If the adapter never reappears after the driver install, contact Acer
- !If it works only intermittently, ask about the Wi-Fi and Bluetooth card
- !Do not open the laptop under warranty
