    temperature values is always 0

    Re: temperature values is always 0

    Hello, 

     

    I looked into your code, and your sleep fucntion is USTIMER_Delay which could be micro second delay. 

    However, our sleep function is mili second based. 

    /*!
    * @brief System specific implementation of sleep function
    *
    * @param[in] t_ms time in milliseconds
    *
    * @return none
    */
    void sleep(uint32_t t_ms)
    {
    // ...
    // Please insert system specific function sleep or delay for t_ms milliseconds
    // ...
    }

    Could you modify it and run it again ?

    Thanks,

    Thank You for your help!

    micro second delay was the problem.It's now working

    Hi,

    I am also using the same EFR32BG22 (Cortex M33) with BME68x.

    I can compile the source, but it is unable to get the library source.

    Could share the supported library for compiling my whole source with BSEC algorithm with bsec_iot_example source.

    If you could share your source or project to compile the same.

    My compiler details:

    arm-none-eabi-gcc -g3 -gdwarf-2 -mcpu=cortex-m33 -mthumb -mfpu=fpv5-sp-d16 -mfloat-abi=hard

    I can read the sensor values from bme68x sensor with raw level without using BSEC algorithm.

    Regards,

    Kumar

    Hi, 

    Unfortuantely, M33 is currently not supported. 

    Please check it in our github.

    Hi Minhwan,

    Thanks for your response.

    In this same mail thread other person JimitP is also using the same EFR32BG Cortex-M33 platform. He said it is working with BSEC algorithm and shared his output results in previous messages.

    I am also using the same platform and as per your mail said it is not supported for Cortex-M33.

    Please check once and share the feedback. Now we have already made PCB based on your BME688 sensor and able to read only raw level via i2c.

    But for checking the GAS related factors it required your BSEC to convert in different ppm values. 

    check with others and share your feedback.

    Regards,

    Kumar
