Frame76:Link Key request event
该Event参数为BR_ADDR
00010111 00000110 10000000 10011001 00100011 01001100 11100000 00000000
Bluetooth Device Address: 0x00-e0-4c-23-99-80
注:该Event应该是对Authentication requset command的后续回应,向本地的Host要Link key。
Frame77:Link Key Negative request command
00001100 00000100 00000110 10000000 10011001 00100011 01001100 11100000 00000000
Bluetooth Device Address: 0x00-e0-4c-23-99-80
注:回应远端slave的Link Key request event,表示本地没有存储的Link Key。
Frame78:Link Key Negative request command---command complete event

00110001 00000110 10000000 10011001 00100011 01001100 11100000 00000000
BD_ADDR: 0x00e04c239980
注:该event表示远端的slave要求本地Host的IO_Capability,这个参数将在pair的过程中用到。
Frame80:IO Capability Request Reply command
这个command的参数如下:
BD_ADDR,
IO_Capability,
OOB_Data_Present,
Authentication_Requirements
00101011 00000100 00001001 10000000 10011001 00100011 01001100 11100000 00000000 0000000100000000 00000101

OOB Data Present: 0x00 OOB authentication data not present
Authentication_Requirements:0x05 MITM Protection Required
– General Bonding. Use IO capabilities to determine authentication procedure.
– General Bonding. Use IO capabilities to determine authentication procedure.
注:这是本地的Host回应远端的IO Capability request event的,表明本地Host具有的IO Capability。
Frame81:IO Capability Request Reply command--command complete
Frame82:IO Capability response event
该Event参数如下:
BD_ADDR,
IO_Capability,
OOB_Data_Present,
Authentication_Requirements
00110010 00001001 10000000 10011001 00100011 01001100 11100000 00000000 0000000100000000 00000000
BD_ADDR: 0x00e04c239980
IO Capability: DisplayYesNo
OOB Data Present: OOB authentication data not present
Authentication_Requirements:0x05 MITM
Protection Required – General Bonding. Use IO capabilities to determine authentication procedure.
Protection Required – General Bonding. Use IO capabilities to determine authentication procedure.
注:这个event由远端的Slave产生,用来回复IO Capability Request Reply command,参数也都基本一样,作用就是表明你的IO capability我已经收到了,是不是感觉有点多此一举呢??
Frame83:User Confirmation Request event
参数如下:
BD_ADDR,
Numeric_Value
00110011 00001010 10000000 10011001 00100011 01001100 11100000 00000000 10110000
10111101 00001000 00000000
10111101 00001000 00000000
BD_ADDR: 0x00e04c239980
Numeric Value: 0x0008bdb0
注:远端的slave要求一个Numeric value,本地的Host可以用User_Confirmation_Request_Reply 或者the
User_Confirmation_Request_Negative_Reply command来进行回应。
Frame84:User Confirmation Request Reply command
00101100 00000100 00000110 10000000 10011001 00100011 01001100 11100000 00000000
Bluetooth Device Address: 0x00-e0-4c-23-99-80
注:响应User Confirmation Request event,表示这个Numeric value实在正确的。
