    Nicla Sense ME Problem with Temperature

    Nicla Sense ME Problem with Temperature

    Hello,

    I have a problem with the temperature measurement on Nicla Sense ME. When I read the temperature value (normal and BSEC), a distorted value comes out, which is slightly above the real value. I have already found this post in the forum where a software update was suggested from @BSTRobin . However, this does not fix the error (they only addded a wrong offest), moreover, with this program the microcontroller crashes after a short time. Also the linear regression mentioned in the post doesnt fix my problem. Since this is a relatively expensive item, I expect that there must be a solution for this temperature offset. I used the program "Standalone" from the official library for testing. 

    I also used this programm to measure the temperature and the BSEC.

    #include "Arduino.h"
    #include "Arduino_BHY2.h"
    
    Sensor temp(SENSOR_ID_TEMP);
    
    SensorBSEC bsec(SENSOR_ID_BSEC);
    
    
    void setup()
    {
      Serial.begin(115200);
      while(!Serial);
    
      BHY2.begin();
    
      temp.begin();
      bsec.begin();  
    }
    
    void loop()
    {
      static auto printTime = millis();
    
      // Update function should be continuously polled
      BHY2.update();
    
      if (millis() - printTime >= 1000) {
        printTime = millis();
        Serial.println(String("temperature: ") + String(temp.value(),3));
        Serial.println(String("bsec: ") + bsec.toString()); 
      }
    }

    I look forward to your help!

    Hi michibit,

    You can refer the temperature compenstion mentioned in this link https://community.bosch-sensortec.com/t5/MEMS-sensors-forum/Nicla-Sense-ME-temperature-and-humidity-...
