[ermix]

Hi, I have this trouble, can't seem to solve it. When I read the previous configuration and pass it to the sensor I get this error:

BME688 status 1 error code : -34

The solutions found in the forum did not help me.

Bsec Library 1.4.9.2

Thanks,

Hi ermix,

Error -34 shows that the version of the configuration file does not match the current BSEC version. You need to ensure that you use a version of the BSEC software and the corresponding configuration file.

BSEC_E_CONFIG_VERSIONMISMATCH = -34, /*!< Version encoded in serialized_[settings/state] passed to bsec_set_[configuration/state]() does not match with current version */

Thank you for your reply, I had some difficulty because the error description was a bit generic and not specific.
I have now got around to converting all the software for BSEC2 - 2.5.0.2 version and everything seems to be working correctly.
