My OnePlus12 is paired to my Dell Inspiron 5580 laptop with Windows 10 Pro 64 Bit 19045.4291. However it does not connect. After pairing Device Manager shows 3 Bluetooth Peripheral Devices, 1 OAF_INSECURE_RFCOMM and 1 OAF_RFCOMM under Other Devices. From where do I get the correct drivers? The Dell laptop drivers are already updated.
The only drivers you need in this case should be Bluetooth driver. Show us a screenshot of device manager.
@windows.seven Then it's easier. Simply delete your device from the Phone Link app, then close Phone Link completely. Then delete your phone from the computer's Bluetooth list as well. It is recommended to set the app not to start automatically (later you can change it to start automatically again). Clean as much as you can - I don't know what you use, but CCleaner does it perfectly enough. Then restart the computer, restart is not necessary for the phone. Then start the app on the computer and start everything from the beginning, i.e. register the phone again, you can enter the code, enable the app, etc. You will be given instructions all the time. And everything should work if you do everything in the right order and enable the connection between the phone and the computer. I warn you that such a situation may occur in the future again (sometimes after updates), then you have to repeat exactly the same thing. But as for the drivers, they are downloaded and installed automatically and you don't need to do anything extra. I can't recommend anything more at the moment, it's just that something has gone wrong somewhere or something is missing when registering the device (the connection between the phone and the computer).
There is no need because everything is working. It was a misunderstanding from my side. Thanks for your advice.
