Hello,

I test the BoschXDKCloudConnectivity project. I found some strange data.

Regarding the Temperature data, It is over 33 degree.

But, I measure the data in office. So it has some gap.

 

Could you know temperature sensor vlaue high?

Hello Choi,

the temperature difference you are observing results from the self heating of the XDK housing while the XDK is running. Since this is a known issue, the temperature compensation functionality has been added in the SDK.

Currently, the default value is set to 3.459 degree. In that regard, you can freely adjust the parameter TEMPERATURE_OFFSET_CORRECTION in the file LWM2MSensorDeviceEnvironmental.c .

Furthermore, you have to find the sufficient temperature compensating value by yourself depending on your environmental temperature. Normally this is around 5-6 degrees.

You can find the variable by navigating to the following folder:

SDK > xdk110 > Common > source > Connectivity > LWM2M

Please let me know if this was helpful, and do not hesitate to ask further questions.

Kind regards,
Franjo

If not already noticed - check humidity too.
Same issue - but always lower.
