Bluetooth record

The Bluetooth record was defined to simplify the pairing between a host and a Bluetooth

device. The host shall know the Bluetooth address to initialize the communication with the

Bluetooth device. The NDEF message contains the information required on the Bluetooth

device (its address, name, class…) to identify it and to promptly initialize a communication

between the host and the Bluetooth device. For example, the host is an NFC mobile phone

and the Bluetooth device is a headset. The contactless tag that contains the NDEF

message, thus the Bluetooth record, is on the headset. The NFC mobile phone will first read

the NDEF message and then initialize the Bluetooth communication with the headset.

The Bluetooth record is defined in the NFC forum application document and provides the

required information to carry out the pairing between the host and the Bluetooth device.

The Bluetooth record is composed of three records, as shown in the following table.
