+ * @ingroup libNDEF
+ * @{
+ * @brief This module is used to manage a Bluetooth Out-Of-Band NDEF message, to start a communication based on Bluetooth.
+ * @details The Bluetooth OOB format is described by the Bluetooth v4.0 core specification.
+ * It consists in a list of Extended Inquiry Responses formated as length-type-value.
+ * This module allows to build, write & read such data embedded in a NDEF message.
+ * @section Bluetooth_Library_Usage Bluetooth NDEF Library usage
+ * @subsection Bluetooth_Write_BrEdr How to write a Bluetooth Br/Edr OOB
+ * 1. Instanciate & initialize a `Ndef_Bluetooth_OOB_t` structure, specifying:
+ * - the `NDEF_BLUETOOTH_BREDR` type.
+ * - the mandatory Device Address field.
+ * - any other optional EIRs.
+ *
+ * Ndef_Bluetooth_OOB_t w_bredr_oob = { .Type = NDEF_BLUETOOTH_BREDR,
+ * .DeviceAddress = {0x01, 0x02, 0x03, 0x04, 0x05, 0x06},
+ * .OptionalMask = NDEF_BLUETOOTH_OPTION(BLUETOOTH_EIR_COMPLETE_LOCAL_NAME) |
+ * NDEF_BLUETOOTH_OPTION(BLUETOOTH_EIR_DEVICE_CLASS) |
+ * NDEF_BLUETOOTH_OPTION(BLUETOOTH_EIR_SERVICE_CLASS_UUID_COMPLETE_16),
+ * .LocalName = "MyDevice",
+ * .nbUUID16 = 2,
+ * .ClassUUID16 = {0x111E,0x110B},
+ * .DeviceClass = {0x04,0x04,0x20}
+ * };
+ * 2. Clear the NDEF message and call the `NDEF_AppendBluetoothOOB` function to write the OOB:
+ *
+ * NDEF_ClearNDEF();
+ * NDEF_AppendBluetoothOOB ( &w_bredr_oob, NULL );
+ * @note Second parameter of `NDEF_AppendBluetoothOOB` can be used to specify an ID for the OOB record (useful for the NDEF Handover message, where specifying an ID is mandatory)
+ * @subsection Bluetooth_Write_Ble How to write a Bluetooth LE OOB
+ * 1. Instanciate & initialize a `Ndef_Bluetooth_OOB_t` structure, specifying:
+ * - the `NDEF_BLUETOOTH_BLE` type.
+ * - the mandatory Device Address & LE Role fields.
+ * - any other optional EIRs.
+ *
+ * Ndef_Bluetooth_OOB_t w_ble_oob = { .Type = NDEF_BLUETOOTH_BLE,
+ * .DeviceAddress = {0x01, 0x02, 0x03, 0x04, 0x05, 0x06},
+ * .DeviceAddressType = NDEF_BLE_PUBLIC_ADDRESS_TYPE,
+ * .Role = NDEF_BLE_ROLE_PERIPH_ONLY,
+ * .OptionalMask = NDEF_BLUETOOTH_OPTION(BLUETOOTH_EIR_COMPLETE_LOCAL_NAME),
+ * .LocalName = "MyDeviceName",
+ * };
+ *
+ * 2. Clear the NDEF message and call the `NDEF_AppendBluetoothOOB` function to write the OOB:
+ *
+ * NDEF_ClearNDEF();
+ * NDEF_AppendBluetoothOOB ( &w_ble_oob, NULL );
+ * @note Second parameter of `NDEF_AppendBluetoothOOB` can be used to specify an ID for the OOB record (useful for the NDEF Handover message, where specifying an ID is mandatory)
+ *
+ * @subsection Bluetooth_Read How to read a Bluetooth OOB
+ * 1. Read the 1st record of the NDEF message:
+ *
+ * sRecordInfo_t record;
+ * NDEF_ReadNDEF(NDEF_Buffer);
+ * NDEF_IdentifyBuffer(record,NDEF_Buffer);
+ * 2. Decode the Bluetooth OOB:
+ *
+ * Ndef_Bluetooth_OOB_t bluetooth_oob;
+ * NDEF_ReadBluetoothOOB(&record,&bluetooth_oob);
+ * 3. Use the data from the `Ndef_Bluetooth_OOB_t` structure to start a Bluetooth connexion.
+ *
