Common APIs#

rsi_common_get_status#

int32_t rsi_common_get_status (void )

rsi_wireless_init#

int32_t rsi_wireless_init (uint16_t opermode, uint16_t coex_mode)

Initialize WiSeConnect or Module features. This is a blocking API. RSI_SUCCESS return value indicates that the opermode and coex value were set successfully in the FW. In case of failure, appropriate error code is returned to the application. Apart from setting WLAN/Coex Operating mode, this API also configures other features based on selected Feature Bitmaps. In this API, configured feature bitmaps are internally processed and sent to firmware. These feature bitmaps are also called Opermode Command Parameters. Default configurations (for reference) are available in rsi_wlan_common_config.h. Based on the features required for a specific example, modify the rsi_wlan_config.h provided in the respective example folder. For more information about these feature bitmaps, refer SP18.

• rsi_driver_init() followed by rsi_device_init() API needs to be called before this API.

Note

• 1. Coex modes are supported only in 384K memory configuration.

• 2. Coex mode 4(Bluetooth classic), 8 (Dual mode), and 12(BLE mode) are not supported.

• 3. To achieve the same functionality, use coexmode 5, 9, and 13 respectively instead of coexmode 4, 8, and 12.

• 4. To achieve power save functionality, trigger 'rsi_wlan_radio_init()' API after rsi_wireless_init() API and also issue both WLAN and BT power save commands.

Returns

• Success - RSI_SUCCESS Failure - Non-Zero Value
