4.2.4.1
Auto Host detection
RS9116 detects the host interface automatically after connecting to respective host controllers like SDIO, SPI, UART,
USB and USB-CDC. SDIO/SPI host interface is detected through the hardware packet exchanges. UART host
interface is detected through the software based-on the received packets on the UART interface. USB-Device mode
interface is detected through the hardware based-on VBUS signal level. The host interface detection between USB &
USB-CDC will be taken care by the firmware based on the USB_CDC_DIS GPIO. This Host configuration is stored in
always-on domain registers after detection (on power up) and reused this information at each wakeup.

4.2.6 Software
The RS9116 software package supports 802.11 b/g/n Client, Access Point (Up to 16 clients), Concurrent Client and
Access Point mode, Enterprise Security, dual-mode BT 5.0 functionality on a variety of host platforms and operating
systems. The software package includes complete firmware, reference drivers, application profiles and configuration
graphical user interface (GUI) for Linux operating systems. The Wi-Fi driver has support for a simultaneous access
point, and c
lient mode. Bluetooth host driver utilizes Opensource host stacks like BlueZ for Linux. The
