RSSI value using Gazell

Question

hi hakon, you told me to do " Try using the variable, for instance by setting "rx_info.rssi = rx_info.rssi;" in the callback and see if that helps." in the question i have asked the link of the question is link text 
 but it couldn't work, i am pasting my code below please see if i am missing something in the code for not getting variable RSSI or send me some working example of getting RSSI using gazel for PCA10001 board. 
 define PIPE_NUMBER 0 ///< We use pipe 0 in this example

// GPIO

 // If an error has occured

 }

 // Optionally send the CPU to sleep while waiting for a callback.
 // __WFI();
}

}

void nrf_gzll_host_rx_data_ready(uint32_t pipe, nrf_gzll_host_rx_info_t rx_info) { 
//uint8_t rss; volatile int16_t rss2; uint32_t data_payload_length = NRF_GZLL_CONST_MAX_PAYLOAD_LENGTH; packet_received = true;

// Pop packet and write first byte of the payload to the GPIO port.
pop_ok1 = nrf_gzll_fetch_packet_from_rx_fifo(PIPE_NUMBER, data_payload1, &data_payload_length);
rx_info.rssi=rx_info.rssi;

if (data_payload_length > 0)
{
 nrf_gpio_pin_set(LED_1);
 nrf_gpio_pin_write(LEDS,~data_payload1[0]);
}

// Read buttons and load ACK payload into TX queue

 please help me out.....
