FAQ

How do I set a custom Bluetooth pairing code?

Enter your preferred 4-digit numeric code in the order notes when purchasing your blafili B3, and we’ll set it before shipping. You can also follow the tutorial on this page to set or change the code yourself.

When does the passcode get asked?

Your phone or tablet prompts for the passcode during pairing. Devices without the code cannot complete pairing.

What if I forget my pairing code?

Use the Bluetooth configuration software to view the pairing code currently saved on your blafili B3. A factory reset only clears saved Bluetooth pairings; it does not remove or reset the code.

Can I set the pairing code from my phone, or do I need a computer?

For the [blafili B3](https://blafili.com/product/blafili-b3-bluetooth-audio-receiver/), plan on a computer. The passcode is written to the receiver with the configuration software shown in the tutorial on this page, which runs on Windows, so a laptop and the USB connection are the tools for the job. There is a no-computer route as well: note your 4-digit code in the order notes when buying, and the receiver ships with the code already stored. Skip both and the B3 simply stays open, because it leaves the factory without any password.

Does setting a passcode change the receiver's Bluetooth name?

No, the two settings are independent. The broadcast name stays whatever it already is, "blafili B3" from the factory unless you renamed it, and adding a passcode touches only the pairing gate. The two combine freely: a custom name makes the unit easy to find in a phone's device list, the code decides who may connect. Every current blafili receiver takes a custom name, while the passcode option lives on the B3 alone.

How do I remove the passcode and go back to open pairing?

Clear the code in the same configuration software and the B3 returns to accepting any pairing attempt, which is its factory state. There is no separate removal tool, and note that a Bluetooth reset on the phone side will not do this job, since the code is stored on the receiver itself. Removal makes sense when the receiver moves to a private room where convenience beats the gate.
