wiced_result_t wiced_average_rssi_enable	(	uint8_t	enable,
		uint16_t	coefficient,
		uint16_t	interval,
		uint8_t	elna_gain,

	)

Function wiced_average_rssi_enable.

Enable the average rssi event

Parameters

[in]	enable	: 1: enable the event 0: disable the event (the same as wiced_average_rssi_disable)
[in]	coefficient	: The paramter will be divided by 1024 as the coefficient in the internal 1st order IIR filter y[n] = ax[n] + (1-a)y[n-1]
[in]	interval	: The timer interval in 100 ms between consecutive average RSSI events
[in]	elna_gain	: The RSSI will be reduced by elna_gain before filtering
[in]	conn_handle_num	: The connection number of conn_handle
[in]	conn_handle	: The array of connection handle

Returns

             WICED_BT_SUCCESS     : Success
             WICED_BT_NO_RESOURCE : No resource to issue command
