BTH_SNIFF_MODE (Windows Embedded CE 6.0)

1/6/2010

This structure stores information about an ACL connection to a peer Bluetooth device that is in SNIFF mode.

Syntax

typedef struct _BTH_SNIFF_MODE {
  unsigned short sniff_mode_max;
  unsigned short sniff_mode_min;
  unsigned short sniff_attempt;
  unsigned short sniff_timeout;
  unsigned short interval;
} BTH_SNIFF_MODE, *PBTH_SNIFF_MODE;

Members

• sniff_mode_max
  The maximum acceptable number of Baseband slots between each sniff period. The time length is equal to N * 0.625 msec, or 1 Baseband slot. The valid range for N is 0x0001 to 0xFFFF. The valid time range is 0.625 msec to 40.9 seconds.

• sniff_mode_min
  The minimum acceptable number of Baseband slots between each sniff period. The time length is equal to N * 0.625 msec, or 1 Baseband slot. The valid range for N is 0x0001 to 0xFFFF. The valid time range is 0.625 msec to 40.9 seconds.

• sniff_attempt
  The number of Baseband receive slots for sniff attempt. The length is equal to (2 * N –1) * 0.625 msec. The valid range for N is 0x0001 to 0x7FFF. The valid time range is 0.625 msec to 40.9 seconds.

• sniff_timeout
  The number of Baseband receive slots for sniff timeout. If N is greater than 0, the length is equal to (2 * N –1) * 0.625 msec. If N is equal to 0, then the length is equal to 0 msec. The valid range for N is 0x0000 to 0x7FFF. The valid time range is 0 msec to 40.9 seconds.

• interval
  The number of Baseband slots between sniff intervals.
