BME280 sample test with nrf5 connect SDK and Visual studio code I2c driver initialization failed chip Id read failed: -5

[Jareena]

Hi,

I am doing BME280 sample Application test with nrf connect SDK v2.5.2 but when I am flashing the code, In serial terminal (Putty) I am facing issue Device BME280 is not ready; check the driver Initialization logs for errors and chip_id read failed: -5 and I am facing one warning missing dependencies in .config file DT_HAS_BOSCH_BME280_ENABLED it is enabled and in .prj config file when iam enabling CONFIG_BME280 but at build time it is showing n and missing dependencies warning. So, can you please, help me through it.

I have added .Overlay file as mentioned below.

&i2c0 {
	compatible = "nordic,nrf-twi";
	status = "okay";

	bme280@76 {
		compatible = "bosch,bme280";
		status = "okay";
		label = "BME280";
		reg = <0x76>;
		
	};
};

and I have added.prj file as mentioned below.

CONFIG_PINCTRL=y
CONFIG_ASSERT=y
CONFIG_TEST_RANDOM_GENERATOR=y
CONFIG_GPIO=y
CONFIG_SERIAL=y
CONFIG_UART_INTERRUPT_DRIVEN=y
CONFIG_TEST_RANDOM_GENERATOR=y
CONFIG_CONSOLE_SUBSYS=y
CONFIG_CONSOLE_GETCHAR=y
CONFIG_STDOUT_CONSOLE=y
CONFIG_CONSOLE=y

CONFIG_CPLUSPLUS=y
CONFIG_LOG=y
CONFIG_SHELL=y
CONFIG_REBOOT=y
CONFIG_PRINTK=y
CONFIG_PM_DEVICE=y

CONFIG_I2C=y
CONFIG_SENSOR=y
CONFIG_BME280=y
CONFIG_BOOT_BANNER=n

At this time, I am facing this issue.

[{
	"resource": "/c:/ncs/v2.5.2/zephyr/samples/sensor/bme280/prj.conf",
	"owner": "kconfig0",
	"severity": 4,
	"message": "CONFIG_BME280 was assigned the value y, but got the value n. Missing dependencies:\nDT_HAS_BOSCH_BME280_ENABLED",
	"startLineNumber": 22,
	"startColumn": 1,
	"endLineNumber": 22,
	"endColumn": 14
}]

and In putty serial terminal Iam getting error like this. So, can you please, help me through this.

Thanks & Regards,

Hi Jareena

Could you try to change your overlay to 

&i2c0 {
	compatible = "nordic,nrf-twim";
	status = "okay";

	bme280@76 {
		compatible = "bosch,bme280";
		status = "okay";
		label = "BME280";
		reg = <0x76>;
		
	};
};

You could check what suggested here  i2c_nrfx_twi: Error 0x0BAE0001 occurred for message 0 

The following from the BME280 DS worth noting

 Hi,

I have changed from twi to twim compatible = "nordic,nrf-twim"; at that time I am facing errors and with version v1.6.0 in nrf connect SDK and with vs code it is working but in v2.5.2 it is not working and same issue iam getting in serial terminal.

[00:00:00.751,434] <err> i2c_nrfx_twi: Error on I2C line occurred for message 0
[00:00:00.751,525] <dbg> BME280: bme280_chip_init: ID read failed: -5
*** Booting nRF Connect SDK v2.5.2 ***

Error: Device "BME280" is not ready; check the driver initialization logs for errors.

Thanks,

Just to make sure that I understand correctly 

After the change it works for NCS v1.6, but it does not work for NCS 2.5.2? 

Are you using one of the samples for the sensor or is this code you have developed?  
Could you also try to change address id to 0x77?

Hi,

Without making the change by placing twi only it works in v1.6 by adding below mentioned llines of configuration

&i2c0 {
    status = "okay";
     bme280@76 {
		compatible = "bosch,bme280";
		reg = <0x76>;
		label = "BME280";
	};
};

But in v2.5.2 sdk it is not working.

And I have tried with register address 0X77 but same error is showing in serial terminal (Putty).

Thanks & Regards,

Shaik Jareena.

Okey thank you. Could you try the BME280 Sample and see if it works for you? 

Also, do you use the same project for both NCS v1.6 and V2.5.2?

Hi,

I have tried with BME280 Sample only with nrf Connect SDK and VS code and with V1.6 it is working same code is not working for V2.5.2.

Also, do you use the same project for both NCS v1.6 and V2.5.2?

Yes, same project only I am used for both NCS v1.6 and V2.5.2 but it is working in v1.6 but in v2.5.2 i am facing errors as above I have mentioned.

Thanks & Regards,

Shaik Jareena.

Did you create the project in v2.5.2 with the correct toolchain? There has been a lot of updates to the SDK since V1.6 which would break the sample you tried to run something made in v1.6 in v2.5.2.
