BME688 and ESP32 giving BSEC error code : -2

[akshay_]

Hello,

We are using single BME688 sensor with esp32 (ESP-WROVER-KIT V4.1 board) over i2c communication.

Facing BSEC error code : -2 error  while wokring with example https://github.com/boschsensortec/Bosch-BSEC2-Library/blob/master/examples/generic_examples/basic_co...

Bosch-BSEC2-Library : https://github.com/boschsensortec/Bosch-BSEC2-Library/tree/master 
Bosch-BME68x-Library : https://github.com/BoschSensortec/Bosch-BME68x-Library 

We are getting this error as envSensor.run() fails.

On further debuggin in bsec2.cpp file we are failing bsec_do_steps(inputs, nInputs, _outputs, &nOutputs); here, as bsec_do_steps returns BSEC_E_DOSTEPS_VALUELIMITS.

https://github.com/boschsensortec/Bosch-BME68x-Library/tree/master/examples/sequential_mode example is working properly with accurate output.

Any help will be appreciated.

Thank you,
Akshay

Its working only if we comment below lines in function bool Bsec2::processData(int64_t currTimeNs, const bme68xData &data)

if (BSEC_CHECK_INPUT(bmeConf.process_data, BSEC_INPUT_PRESSURE))
    {
        inputs[nInputs].sensor_id = BSEC_INPUT_PRESSURE;
        inputs[nInputs].signal = data.pressure;
        inputs[nInputs].time_stamp = currTimeNs;
        nInputs++;
    }

And we are not able to read pressure measurement because of that, what coud be the reason as we are using example code basic.ino as it is, just changed I2C pin Wire.setPins(33, 32);
