In Bluetooth pairing, what is a common default PIN code reported by Technician B?

In Bluetooth pairing, a common default PIN code that many devices use is 0000. This PIN has become widely recognized and is often employed by various manufacturers as a default for setting up Bluetooth connections. The simplicity of using four zeros makes it easy for users to remember and enter, facilitating the pairing process between devices. It's essential to note that many devices will request this PIN during the initial pairing phase, as it serves as a basic security measure to ensure that both devices confirm their willingness to connect.

Other commonly used default PIN codes, while they may appear in some devices, are less universally recognized, which is why 0000 is often referenced as the standard in many technical discussions and documentation regarding Bluetooth technology. This makes it practical for technicians and users to be aware of as they troubleshoot or set up Bluetooth connections.
