CC115L: Not able to get proper data by transmitter

Dear TI E2E Team,

I am not getting proper data by transmitter.

I followed these steps.

1. CS=LOW, Initialize the register in brust mode, Not used register written  = 0x00, 

reserved and register value taken from rf studio. CS=HIGH

.

//RADIO_WRITE_ACCESS|RADIO_BURST_ACCESS|CC115L_IOCFG2 = 0x40

uint8_t Init_RF_N_Reg[49]= {0x40,0x2E,0x2E,0x06,0x47,0xD3,

                                                                                        0x91,0x1E,0x00,0x04,0x00,

                                                                                        0x01,0x00,0x00,0x10,0x09,

                                                                                        0x7A,0xC8,0x84,0x11,0x22,

                                                                                        0xE5,0x33,0x00,0x30,0x18,

                                                                                        0x00,0x00,0x00,0x00,0x00,

                                                                                        0x00,0x00,0xFB,0x00,0x10,

                                                                                        0xE9,0x2A,0x00,0x1F,0x00,

                                                                                        0x00,0x59,0x7F,0x3F,0x81,

                                                                                        0x35,0x09,0x00};

Highlighted byte is header byte.

2. Command strobe STX

    CS_LO;

    //delay_1ms(1);

    while(SPI_MISO); /* Pull CS_N low and wait for MISO to go low before                   communication starts */

    Com_busy_flag = 0U;

    CMD_Strobe(CC115L_STX);

    while(!Com_busy_flag);

    CS_HI;

3. Send Data

   Payload_buff[0]=CC11xL_FIFO|RADIO_BURST_ACCESS|RADIO_WRITE_ACCESS;

for(i=1;i<31;i++)         Payload_buff[i]=SPEED_0[i];          

     CS_LO;

     delay_1ms(1);

     while(SPI_MISO); /* Pull CS_N low and wait for MISO to go low before communication starts */

     Com_busy_flag = 0U;

     TxRx_Status = R_CSI00_Send_Receive(Payload_buff,31,0U);                        

     while(!Com_busy_flag);

     CS_HI;

4.    CS_LO;

                                    delay_1ms(1);

                                    while(SPI_MISO); /* Pull CS_N low and wait for MISO to go low before communication starts */

                                    Com_busy_flag = 0U;

                                    CMD_Strobe(CC115L_SIDLE);

                                    while(!Com_busy_flag);

                                    delay_1ms(1);

                                    CS_HI;

I am getting corrupted data. only 2 or 3 times get actual data. I am using poll mode(i.e. only SPI Connection).
