Problem facing with RSSI value in ESB

Question

Hi, 
 I am using ESB library for nRF52 microcontroller. At receiver i want to measure RSSI value of a packet. I got RRSI from nrf_esb_payload_t structure. 
 I am printing RSSI value in UART but i am getting some random symboals not proper RSSI values. 
 Please help me out. 
 My code main.c

When I test the below, reading out the RSSI from the NRF_LOG_DEBUG, the RSSI values seems likely to be correct:

case NRF_ESB_EVENT_RX_RECEIVED:
        NRF_LOG_DEBUG("RX RECEIVED EVENT\r\n");
        if (nrf_esb_read_rx_payload(&rx_payload) == NRF_SUCCESS)
        {
            // Set LEDs identical to the ones on the PTX.
            nrf_gpio_pin_write(LED_1, !(rx_payload.data[1]%8>0 && rx_payload.data[1]%8<=4));
            nrf_gpio_pin_write(LED_2, !(rx_payload.data[1]%8>1 && rx_payload.data[1]%8<=5));
            nrf_gpio_pin_write(LED_3, !(rx_payload.data[1]%8>2 && rx_payload.data[1]%8<=6));
            nrf_gpio_pin_write(LED_4, !(rx_payload.data[1]%8>3));

            NRF_LOG_DEBUG("Receiving packet: %02x\r\n", rx_payload.data[1]);
	        NRF_LOG_DEBUG("RSSI: %02x\r\n",rx_payload.rssi );
        }
        break;

What kind of values do you read from the RSSI measurements? Does the baudrate in your firmware match the baudrate in the terminal?
