RSSI or Received Signal Strength Indicator is the measurement of the power present in a received radio signal.

Use the wiced_wifi_get_associated_client_list( ) function to get the list of stations connected to the WICED SoftAP. The MAC address of each connected client is stored in a wiced_mac_t type structure.

wiced_mac_t is defined as:

 

typedef struct  

{

    uint8_t octet[6]; /**< Unique 6-byte MAC address */

} wiced_mac_t;

The mac address can then be passed to the function wiced_wifi_get_ap_client_rssi( ):

int32_t             rssi = 0;

int                   client_number = 0;

wiced_result_t  result;

struct

{

    int    count;

    wiced_mac_t     mac_list[MAX_SOFT_AP_CLIENTS];

} client_info;

/* Get the list of the stations connected to Wiced soft AP */

result = wiced_wifi_get_associated_client_list( &client_info, sizeof(client_info) );

if ( result == WICED_SUCCESS )

{

    for ( client_number=0; client_number < client_info.count; client_number++ )

    {

        /* Get the RSSI of every client currently connected to the soft AP */

        result = wiced_wifi_get_ap_client_rssi(&rssi, &client_info.mac_list[client_number]);

      

        if ( result == WICED_SUCCESS )

        {

            WPRINT_APP_INFO(("| %d | %02x:%02x:%02x:%02x:%02x:%02x | %3lddBm |\r\n",

                                            client_number,

                                            client_info.mac_list[client_number].octet[0],

                                            client_info.mac_list[client_number].octet[1],

                                            client_info.mac_list[client_number].octet[2],

                                            client_info.mac_list[client_number].octet[3],

                                            client_info.mac_list[client_number].octet[4],

                                            client_info.mac_list[client_number].octet[5],

                                            rssi ));           

        }

    }

}

API Details:

wiced_result_t wiced_wifi_get_associated_client_list ( void *    client_list_buffer,

                                                                                    uint16_t          buffer_length )                             

Gets information about associated clients.

Note:

Only applicable if softAP interface is up

Parameters

I/O

Description

client_list_buffer

out

Pointer to a buffer that will be populated with a variable length structure defined by wiced_maclist_t.

buffer_length

in

Length of the buffer.

Return

WICED_SUCCESS if client list retrieval is successful.

wiced_result_t wiced_wifi_get_ap_client_rssi( int32_t* rssi,  wiced_mac_t* client_mac_addr )

Retrieve the latest RSSI value of the AP client.

Parameters

I/O

Description

rssi

out

Latest RSSI of the client.

client_mac_addr

in

Mac address of the AP client

Return

WICED_SUCCESS if RSSI is successfully retrieved.
