CCS/MSP430FR6989: I2C Read issues with BME280

Tool/software: Code Composer Studio

Hi

I am trying to have single i2c function to read single or multiple bytes. Below is a part of the code

unsigned char * i2c_data;
unsigned char RX_Data;

unsigned char * i2c_read(unsigned char slv_addr, unsigned char reg_addr, unsigned int len){

    unsigned char data[36];
    unsigned int i = 0;

    while(UCB1STAT & UCBBUSY);
    UCB1I2CSA = slv_addr;
    UCB1CTLW0 |= UCTR | UCTXSTT;

    while(UCB1CTLW0 & UCTXSTT);
    UCB1TXBUF = reg_addr;
    while(!(UCB1IFG & UCTXIFG0));

    UCB1CTLW0 &= ~UCTR;
    UCB1CTLW0 |= UCTXSTT;

    while(UCB1CTLW0 & UCTXSTT);

    for(i = 0; i < len; i++)
    {
        if(i == len - 1)
        {
            UCB1CTLW0 |= UCTXSTP;
        }
        while(!(UCB1IFG & UCRXIFG0));

        data[i] = UCB1RXBUF;
    }

    while(UCB1CTLW0 & UCTXSTP);

    return(data);
}

When I check for the read value against the desired value, it is true but when I try to print the value, I am getting junk.

i2c_data = i2c_read_bytes2(BME280_I2C_ADDRESS, BME280_CHIP_ID_ADDR, 1);
if(i2c_data[0] == 0x60)
    {
        uart_puts("Chip Address is: ");
        sprintf(RX_Data, "%x", i2c_data);
        uart_puts(RX_Data);
        uart_puts("\r\n");
    }

It is printing 2Ðð instead of 60
