About fritz

Hello Faham, obviously you are trying to use Pi3g bme68x _python_ library, which is using currently BSEC 2.0.6.1 version of Bosch BSEC library. In order to use this python lib with the latest BSEC 2.2.0.0 you have to adapt it by yourself or kindly ask Pi3g guys to do so officially on their Gir repo. I did it alredy for me, please find the patched files in att. BR's   -fritz ... View more

Hello Minhwan, yes, I've used the recomended versions of the libraries as mentioned on the projects GIT readme page: ArduinoJson (tested for 6.19.4 by Benoit Blanchon) RTClib (tested for 2.0.3 by Adafruit) SdFat (tested for 2.1.2 by Bill Greiman) and ended up with 104% of program storage space. Sketch uses 1375781 bytes (104%) of program storage space. There is only one newer version of mentioned libs available: RTClib verson 2.1.1. Using this doesn't contribute to the overall program size significantly: +112 bytes Sketch uses 1375893 bytes (104%) of program storage space. BR's,  -fritz ... View more
