Revision X2
0 COEXISTENCE_NONE PIO is not used (high impedance)
1 COEXISTENCE_BT_OUTPUT PIO is asserted for the duration of
SCO and eSCO reserved slots
With current firmware builds this should be left at its default of COEXISTENCE_BT_OUTPUT, with the
functionality enabled or disabled by modifying PSKEY_LC_COMBO_DOT11_PERIODIC_PIO_MASK
as
appropriate.
Note: For correct operation of COEXISTENCE_BT_OUTPUT it is necessary to also set
PSKEY_LC_COMBO_DOT11_ESCO_RTX_PRIORITY
= TRUE.

PSKEY_LC_COMBO_DOT11_T1 0x005e uint16 150

Type Default Setting
PSKEY_LC_HIGH_PRIORITY_SNIFF_TIMEOUTS 0x0060 bool FALSE
This key affects the algorithm that selects the value of Dsniff when negotiating sniff mode for an ACL
connection. If no value is set or the value is FALSE, sniff timeout slots will not be included in the
calculation unless the quality of service for the connection is "guaranteed". If the value is TRUE, sniff
timeout slots will always be taken into account: this means that extra spacing is left in the air time schedule,
where possible, to allow for a transmission to a slave during one iteration of the timeout slots.
This key has no direct effect on the real-time scheduling of links in sniff mode, so it does not necessarily
cause a master to address the slave in the timeout slots. A QoS setting of "guaranteed" for an ACL
connection causes sniff timeout slots to be treated as high priority by the real-time scheduler; however, that
should be used with caution as it can have a significant effect on the bandwidth available for other links.
(Type bool is fundamentally a uint16 with values 0 and 1 mapping to FALSE and TRUE.)
Key Name Key Number Type Default Setting
PSKEY_FREE_KEY_PIGEON_HOLE 0x00c9 uint16 0
A bitfield indicating which link keys are stored. A 1 in this mask indicates that the corresponding link key
is occupied.
Freaky pigeon hole?
