RK3308 WIFI Interface Introduction Preface Contents 1. Overview 2. Interface Introduction 3. Application Demo
1. Overview
This code module is integrated in the libDeviceIo.so dynamic library and it is a WIFI operation interface based on WPA package.
2. Interface Introduction
RK_WIFI_RUNNING_State_e
About several status definitions of WIFI :
| 1 typedef enum { 2 RK WIFI State IDLE = 0, _ _ _ 3 RK WIFI State CONNECTING, _ _ _ 4 RK WIFI State CONNECTFAILED, _ _ _ 5 RK WIFI State CONNECTFAILED WRONG KEY, _ _ _ _ _ 6 RK WIFI State CONNECTED, _ _ _ 7 RK WIFI State DISCONNECTED _ _ _ 8 } RK WIFI RUNNING State e; _ _ _ _ | |
|---|---|
| 1 2 3 4 5 6 7 8 | typedef enum { RK WIFI State IDLE = 0, _ _ _ RK WIFI State CONNECTING, _ _ _ RK WIFI State CONNECTFAILED, _ _ _ RK WIFI State CONNECTFAILED WRONG KEY, _ _ _ _ _ RK WIFI State CONNECTED, _ _ _ RK WIFI State DISCONNECTED _ _ _ } RK WIFI RUNNING State e; _ _ _ _ |
| RK WIFI CONNECTION Encryp e _ _ _ _ |
There are three WIFI encryption types: passwordless, WPA and WEP.
| 1 typedef enum { 2 NONE = 0, 3 WPA, 4 WEP 5 } RK WIFI CONNECTION Encryp e; _ _ _ _ | |
|---|---|
| 1 2 3 4 5 | typedef enum { NONE = 0, WPA, WEP } RK WIFI CONNECTION Encryp e; _ _ _ _ |
| RK WIFI INFO Connection s _ _ _ _ |
Please refer to wpa_cli -iwlan0 status for WIFI status information.
| 1 typedef struct { 2 int id; 3 char bssid[20]; 4 char ssid[64]; 5 int freq; 6 char mode[20]; 7 char wpa state[20]; _ 8 char ip address[20]; _ 9 char mac address[20]; _ 10 } RK WIFI INFO Connection s; _ _ _ _ | |
|---|---|
| 1 2 3 4 5 6 7 8 9 10 | typedef struct { int id; char bssid[20]; char ssid[64]; int freq; char mode[20]; char wpa state[20]; _ char ip address[20]; _ char mac address[20]; _ } RK WIFI INFO Connection s; _ _ _ _ |
| i |
To register the WIFI status callback interface, and callback when WIFI status changes.
int RK_wifi_ble_register_callback(RK_wifi_state_callback cb)
The BLE WIFI callback interface, which is used for callback status during BLE network configuration.
int RK_wifi_running_getState(RK_WIFI_RUNNING_State_e* pState)
To get current WIFI status and return 0 if successful.
int RK_wifi_running_getConnectionInfo(RK_WIFI_INFO_Connection_s* pInfo)
To get current WIFI connection information.
int RK_wifi_enable_ap(const char* ssid, const char* psk, const char* ip)
To enable softAp based on the value of ssid, psk and ip.
int RK_wifi_disable_ap()
Close softAp.
int RK_wifi_scan(void)
Please refer to wpa_cli -iwlan0 scan and execute WIFI sacn operation .
char* RK_wifi_scan_r(void)
Please refer to wpa_cli -iwlan0 scan_r,and get WIFI scan result, and return JSON.
char* RK_wifi_scan_r_sec(const unsigned int cols)
Please refer to RK_wifi_scan_r(void), and get specified column from WIFI scan result, and return JSON.
bssid / frequency / signal level / flags / ssid
To use 5 binary numbers to represent the above data in order from left to right. For example, RK_wifi_scan_r_sec (0x01) is used to get bssid data, RK_wifi_scan_r_sec (0x10) is used to get ssid data, and RK_wifi_scan_r_sec (0x1F) is used to get all data.
int RK_wifi_connect(const char* ssid, const char* psk)
Connect the specified hotspot by the default WPA encryption method.
int RK_wifi_connect1(const char* ssid, const char* psk, const
RK_WIFI_CONNECTION_Encryp_e encryp, const int hide)
Please see RK_wifi_connect interface for expanding encryption type, ssid hidden parameter.
int RK_wifi_disconnect_network(void)
To disconnect WIFI connection.
int RK_wifi_set_hostname(const char* name)
To configure hostname.
int RK_wifi_get_hostname(char* name, int len)
To get hostname.
int RK_wifi_get_mac(char *wifi_mac)
To get mac address.
int RK_wifi_has_config(void)
To check whether the network been configured.
int RK_wifi_ping(void)
To check whether the network is connected by ping.
