#include <zephyr.h>
#include <device.h>

#include <drivers/i2c.h>
#include <sys/printk.h>

#define BME280_ID_REG					0xD0

#define I2C0_NODE DT_NODELABEL(mysensor)

uint8_t id_read[1] ;

void main(void)
{

	static const struct i2c_dt_spec dev_i2c = I2C_DT_SPEC_GET(I2C0_NODE);
	
	if (!device_is_ready(dev_i2c.bus)) {
		printk("I2C bus %s is not ready!\n\r",dev_i2c.bus->name);
		return;
	}

	uint8_t id_write[1] = {BME280_ID_REG};
	
	while (1)
	{
		i2c_write_read_dt(&dev_i2c,&id_write[0],1,&id_read[0],1);
		printk("%d\n",id_read[0]);
	}
}

overlay file

&i2c0 {
    
    mysensor: mysensor@76{
        compatible = "bosch,bme280";
        reg = < 0x76 >;
        label = "MYSENSOR";
    };
};

I am referring that only , and as a first step I am just trying to get the ID . I am not receiving any ID value.

Hello Manas,

In order to get familiar with NCS I would recommend you to take a look at out DevAcademy.
