Issue with Reading BMP280 Chip ID using SPI

[Kaarthy]

Context: I am trying to read the Chip ID from a BMP280 sensor using SPI communication with an STM32 microcontroller. The expected Chip ID value is 0x58. However, I am encountering inconsistent results when calling the function to read the Chip ID multiple times.

BMP280_Read_CHIP_ID();
BMP280_Read_CHIP_ID();

Problem: When I call the BMP280_Read_CHIP_ID function twice consecutively, I get the following outputs:

1. Chip ID Read - 0
2. Chip ID Read - 58

UART Output.

The first read returns 0x00 (unexpected), while the second read returns the correct Chip ID 0x58.

Code:

Here is the function I am using to read the Chip ID:

void BMP280_Read_CHIP_ID()
{
    uint8_t data = 0;
    uint8_t address = 0xD0;
    address |= 0x80;
    CS_Enable();
    delay_ms(2);
    SPI_Transmit(&address, 1);
    delay_ms(2);
    SPI_Receive(&data, 1);
    delay_ms(2);
    CS_Disable();
    printf("Chip ID Read - %x\n\r", data);
}

SPI_Transmit Function:

void SPI_Transmit (uint8_t *data, int size)
{
	int i=0;
	while (i<size)
	{
	   while (!((SPI1->SR)&(1<<1))) {}; 
	   SPI1->DR = data[i]; 
	   i++;
	}

	while (!((SPI1->SR)&(1<<1))) {}; 
	while (((SPI1->SR)&(1<<7))) {}; 

	//  Clear the Overrun flag by reading DR and SR
	uint8_t temp = SPI1->DR;
	temp = SPI1->SR;

}

SPI_Receive Function:

void SPI_Receive (uint8_t *data, int size)
{
	while (size)
	{
		while (((SPI1->SR)&(1<<7))) {};
		SPI1->DR = 0;  // send dummy data
		while (!((SPI1->SR) &(1<<0))){}; 
	     *data++ = (SPI1->DR);
		size--;
	}
}
