ADV_DIRECT_IND: for attachable directional broadcasting event;
ADV_NONCONN_IND: for not attachable non-directional broadcast event;
ADV_SCAN_IND: for the non-directional broadcast event that can scan;
These PDU types send by the link layer in broadcast state.
PDU type ADV_IND, ADV_NONCONN_IND and ADV_SCAN_IND are separately for " non-directional " broadcast event, this means that transmission is to unspecific recipient broadcast, the equipment that can be in any suitable configurations in the transmission range of transmitting apparatus receives.ADV_IND type can be used for connecting with one or more receiving equipments, and ADV_NONCONN_IND type can be used for the attachable or not unidirectional communication of one or more receiving equipments, and ADV_SCAN_IND type can be used for scanning broadcast event.The payload 964 of all three PDU type ADV_IND, ADV_NONCONN_IND and ADV_SCAN_IND is identical.As shown in figure 10, payload 964 is comprised of broadcast address (AdvA) field 1200 and broadcast data (AdvData) field 1400.6 8Bit that AdvA field 1200 comprises public or random device address, the Bluetooth address of expression data receiver.AdvData field 1400 can comprise 0 to 31 8Bit of broadcast data, contain some AD Structure(AD structures) and remaining complete ' 0 ' part, each AD structure comprises a length field and data field, and each data field also comprises AD type and AD data.。Can for manufacturer data, retain the 8Bit0 and 1 of AdvData field 1400, leave 8Bit2 to 31 for broadcast data, but when not needing such manufacturer data, can be by all 8Bit0 to 31 for broadcast data.
In various embodiments of the present invention, used two kinds of new low-power consumption bluetooth PDU types (PDU Type) to come broadcast request message and response message, the definition of the two is as shown in the table respectively:
Table 1
PDU type code (b 3b 2b 1b 0) PDU type
1000(or other retention) ADV_ACSINF_REQ
1001(or other retention) ADV_ACSINF_REP
The payload format of the two and the message shown in Figure 10 are similar, comprise AdvA and broadcast data AdvData two parts, but difference to some extent on the concrete form of broadcast data.Particularly, the broadcast data of ADV_ACSINF_REQ contains target access point identification, and in ADV_ACSINF_REP broadcast data, contains some accessing points information, and the AD type that accessing points information is used defines in table 2.
Table 2
Wherein, it should be noted that, complete accessing points information (AO/AC information) should occur in pairs, otherwise should regard as invalid; Only allow ADV_ACSINF_REQ message to contain single AO information (as invalid in occurred that AC should regard as).And if space permission, organize AO/AC information more and can be placed in same payload.For example a key provider can provide many group AO/AC information.For example an ADV_ACSINF_REQ can comprise a plurality of AO, different key providers can reply respectively according to the information of self (in this situation for fear of conflict, can adopt send SCAN_RSP dodge at random strategy).According to bluetooth 4.0 standards, the maximum length of payload is 29 bytes, this means if AO/AC surpasses this restriction, can not be encapsulated in a broadcast channel message.As a kind of replacement scheme, now allow a part of intercepting AO to replace complete AO.
