I have same issue with BSEC 1.4.7.3. I am able to compile in Mac and Linux with Arduino 1.8.5 - 1.8.8, but iaqSensor.run() always fails ( status -2 ). 12:08:43.344 -> BSEC library version 1.4.7.3
12:08:43.344 -> Timestamp [ms], raw temperature [°C], pressure [hPa], raw relative humidity [%], gas [Ohm], IAQ, IAQ accuracy, temperature [°C], relative humidity [%], Static IAQ, CO2 equivalent, breath VOC equivalent
12:08:43.587 -> BSEC error code : -2 Only thing I change from basic example is iaqSensor.begin(BME680_I2C_ADDR_SECONDARY, Wire); As my sensor is at 0x77 Basic_data_loging example works fine with "envSensor.begin(BME680_I2C_ADDR_SECONDARY, Wire);" change. How to debug this? I could send my binary if some one one can flash and test in working 0x77 adress device ( LOLIN D1 mini-pro or as requested) ?
