Appendix 3: (The Inquiry Access Codes)

The General-and Device-Specific Inquiry Access Codes (DIACs)

The Inquiry Access Code is the first level of filtering when finding Bluetooth devices.

The main purpose of defining multiple IACs is to limit the number of responses that are

received when scanning devices within range.

0. 0x9E8B33 ---- General/Unlimited Inquiry Access Code(GIAC)

1. 0x9E8B00 ---- Limited Dedicated Inquiry Access Code(LIAC)

2. 0x9E8B01 ～ 0x9E8B32 RESERVED FOR FUTURE USE

3. 0x9E8B34 ～ 0x9E8B3F RESERVED FOR FUTURE USE

The Limited Inquiry Access Code(LIAC)is only intended to be used for limited

time periods in scenarios where both sides have been explicitly caused to enter this state,

usually by user action. For further explanation of the use of the LIAC, please refer to the

Generic Access Profile.

In contrast it is allowed to be continuously scanning for the General Inquiry Access

Code (GIAC)and respond whenever inquired.
