Hello Honoju,    Let'd do step by step. I believe that you already put your read and write function ( I2C or SPI. )  But, please check that you put your function like below.    In case of SPI struct bme280_dev dev; int8_t rslt = BME280_OK; /* Sensor_0 interface over SPI with native chip select line */ uint8_t dev_addr = 0; dev.intf_ptr = &dev_addr; dev.intf = BME280_SPI_INTF; dev.read = user_spi_read; dev.write = user_spi_write; dev.delay_ms = user_delay_ms; rslt = bme280_init(&dev);   In case of I2C struct bme280_dev dev; int8_t rslt = BME280_OK; uint8_t dev_addr = BME280_I2C_ADDR_PRIM; dev.intf_ptr = &dev_addr; dev.intf = BME280_I2C_INTF; dev.read = user_i2c_read; dev.write = user_i2c_write; dev.delay_ms = user_delay_ms; rslt = bme280_init(&dev);   i2c spi function type should be followed below url.  https://github.com/BoschSensortec/BME280_driver   And, if you feel all settings are okay, but still there is same issue, you need to capture your data log using like logic analyzer whether MCU can really communicate with sensor.  You can upload your data log if you have any questions for data log.  Thanks,   ...

Hello Carlos,    If you are using exactly same code, you should get within 20mins.  Could you share your code?  Thanks,  ... View more

Hello honoju,    Could you give me what is error code for rslt?  You can print out with rslt value.  And, you can check the error with bme280_defs.h 🙂  Thanks,  ... View more

Hello Charlotte,    I just compared 1.4.7.1 and 1.4.8.0, and there are some changes not only bsec_datatypes.h, bsec_interface.h, but also bsec.cpp and other files.  That means if you are using bsec.cpp, your application code should be changed.  Additionally, we made config folder and managed some config file.  So, I'd ask you to test latest bsec library based on new project.  If you have experience about including library, it could not be difficult.  Please check below URL, and let me know if you have any quetions.  https://github.com/BoschSensortec/BSEC-Arduino-library Thanks,    ...

Hello Carlos,    If you are using 300s interval or ULP mode, it should take longer. Can you test with 3s interval version of config file like generic_33v_3s_28d?  And also for test purpose, please test LP mode, and let me know if you still can't see IAQ change to 1 or 3.  Thanks,  ... View more
