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 ));
}
}
}

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. |
