HCI Vendor Specific Commands
1.1 HCI_EXT_SetRxGainCmd
This command is used to set the RF receiver gain. The default system value for this feature is standard receiver gain.
When the HCI_EXT_SetRxGainCmd has completed, a vendor specific Command Complete event shall
be generated.
1.2 HCI_EXT_SetTxPowerCmd

1.3 HCI_EXT_OnePktPerEvtCmd
此命令用于将链路层配置为仅允许每个连接事件一个数据包。 此功能的默认系统已禁用。 此命令可用于在连接期间权衡吞吐量和功耗。 启用后，可以在连接期间通过将每个连接事件的数据包数量限制为1来节省功率，但代价是更有限的吞吐量。 禁用时，连接事件期间传输的数据包数量不受限制，但代价是功耗较高。
When the HCI_EXT_OnePktPerEvtCmd has completed, a vendor specific Command Complete event shall be generated.
1.4 HCI_EXT_ClkDivOnHaltCmd
