This pskey is primarily intended for use by IEEE 802.11b combo designs. The signalling is used in
combination with PSKEY_LC_COMBO_DOT11_BLOCK_CHANNELS
to disable non-priority Bluetooth
transmissions that may otherwise degrade 802.11b throughput.
Key Name Key
Number
Type Default Setting
PSKEY_LC_COMBO_DOT11_BLOCK_CHANNELS 0x002b uint16 11
Set the number of Bluetooth channels to block on either side of an IEEE 802.11b channel centre frequency.
The default value of 11 results in 23 channels being blocked:
Fc - 11, ..., Fc - 1, Fc, Fc + 1, ..., Fc + 11
This pskey is primarily intended for use by IEEE 802.11b combo designs. The signalling is used in
combination with PSKEY_LC_COMBO_DOT11_CHANNEL_PIO_BASE
to disable non-priority
Bluetooth transmissions that may otherwise degrade 802.11b throughput.
Key Name Key Number Type Default Setting
PSKEY_LC_MAX_TX_POWER_NO_RSSI 0x002d int8 4
This value is used after a connection is made if it is found that a remote device does not support RSSI
measurements or power control. The transmit power is lowered to correspond to the first entry in
PSKEY_LC_POWER_TABLE whose power in dBm is less than or equal to the value of this pskey.
According to the Bluetooth radio specification, a device may only transmit to a peer which does not support
RSSI or the related LMP messaging using the rules for a class 2 or class 3 device, in other words with a
maximum transmit power of 4 dBm, hence the default value for this pskey. This allows the default transmit
power to be raised above 4 dBm without violating the specification.
Key Name Key
Number
Type Default Setting
PSKEY_LC_CONNECTION_RX_WINDOW 0x002e uint16 10
The Bluetooth specification requires that a master or slave be sensitive to timing jitter of transmissions
from the other side up to 10 microseconds while the two devices are connected. The value may be
controlled by this pskey.

Number
Type Default Setting
PSKEY_LC_COMBO_DOT11_TX_PROTECTION_MODE 0x0030 uint16 0
Provides an option to select some Bluetooth packets for protection. The intent is to improve SCO
transmissions in a co-existence scheme.
