hciStatus_t HCI_EXT_SetBDADDRCmd( uint8 *bdAddr )
This command sets the Bluetooth Low Energy address (BDADDR) of the device.
This address overrides the address of the device determined at reset. To restore
the initialized address of the device stored in flash, issue this command with an
invalid address (0xFFFFFFFFFFFF).
Note
NOTE: This command is allowed only when the controller is in the standby state.
TI intends this command to be used only during initialization. Changing
the BDADDR of the device after active Bluetooth Low Energy operations
(i.e. Tx and Rx) have occurred may cause undefined behavior.
Parameters bdAddr – A pointer to a buffer to hold this address of the device. An invalid address (that
is, all FFs) restores the address of this device to the address set at initialization.

hciStatus_t HCI_EXT_SetFastTxResponseTimeCmd ( uint8 control )
This command configures the link layer fast transmit response time feature. The
default system value for this feature is enabled.
Note
NOTE: This command is valid only for a slave controller.
When the host transmits data, the controller ensures the packet is sent
over the LL connection with minimal delay even when the connection is
configured to use slave latency by default. The transmit response time is
no longer than the connection interval, instead of waiting for the next
effective connection interval due to slave latency. The result is lower
power savings because the LL may need to wake to transmit during
connection events that would have been skipped due to slave latency. If
saving power is more critical than fast transmit response time, you can
disable this feature using this command. When disabled, the transmit
response time will be no longer than the effective connection interval
(slave latency + 1 × the connection interval).
Parameters control – HCI_EXT_ENABLE_FAST_TX_RESP_TIME,
HCI_EXT_DISABLE_FAST_TX_RESP_TIME
Corresponding Events HCI_VendorSpecifcCommandCompleteEvent
