PSKEY_LC_WIDEBAND_RSSI_CONFIG 0x0032 wideband_rssi_config 113, 98, 9, 50
Hardware from BlueCore3-Ext has a facility for wideband RSSI measurement. This key is used to
configure the settings.
It consists of four 16-bit words.
The first word is the value of the wideband RSSI reading above which the RSSI high target should be
reduced.
The second word is the value of the wideband RSSI readinb below which the RSSI high target should be
increased.
THe third word is the step used when changing the RSSI high target.
The fourth word is the minimum allowed value of the RSSI high target. The maximum value is
PSKEY_RSSI_HI_TARGET
, or PSKEY_LC_RSSI_GOLDEN_RANGE on builds without
PSKEY_RSSI_HI_TARGET
.
Key Name Key
Number
Type Default Setting
PSKEY_LC_COMBO_DOT11_PRIORITY_LEAD 0x0033 uint16 50
This key is used only when we are using the Intel Phase 2 COEX scheme. This key defines the value for
T_priority_lead which is the time between us raising the BT_Priority signal and the packet header
beggining.
This key might be removed on later builds once a good value has been found.
Key Name Key Number Type Default Setting
PSKEY_BT_CLOCK_INIT 0x0034 uint32 0UL
The value to which the Bluetooth clock will be initialised at boot. The value 0 is standard; the only likely
reason to alter this is for debugging non-CSR devices known to encounter problems at certain clock values.
(Historical note: before this key was introduced, CSR devices initialised their Bluetooth clocks from the
lower 28 bits of the Bluetooth address, i.e. the lower 4 bits of the UAP followed by the LAP.)

Type Default Setting
PSKEY_LC_COMBO_DOT11_FREQ_PIO_MASK 0x0035 uint16 0
This key is used only when we are using some of the more advanced coexistence schemes. This key defines
a PIO mask that shall be used to indicate when we are overlapping in frequency (between the Bluetooth
device and the WLAN device).
Key Name Key Number Type Default Setting
PSKEY_CONDITIONAL_SCAN_ENABLE 0x0036 bool FALSE
If set TRUE (value 1), then the firmware will rapidly scan the Bluetooth band on the first slot pair of a page
or inquiry scan, looking for any transmissions in the band. If it finds none, it will not listen for the
