Does not work with arduino mkr wan 1300 and mkr wifi 1010 probably the mkr lineup... #22

Hey, the problem is that it gets stuck on the gas.begin()...and does not go further... I can see the right address with a i2c scanner, but when I try to read the sensor data nothing happens, The sensor works just fine with arduino uno and nodemcu, and a different sensor(grove eCO2) with the mkr wan 1300 on the same pins and wires works so i know the board is ok... any help?

I'm experiencing the same sort of.... it is constantly saying invalid on my mkr nb 1500 (SAMD21 Arcitercture) but is giving values on my UNO... I need it to work on the mkr board though

Same issue as @lorauser ... it hangs on MKR1000 just after gas.begin(). The same module works with Seeeduino Lotus and Wio Node.

The inline function is supposed to be put in the header file. Otherwise the compiler doesn't know what to insert into the call-sites when it's compiling other source files. It's a problem of the library...
