Hello,
I would like to readout multiple BME688 simultaniously. I created two instances of Bsec2, and afterwards i do each step for both instances. I kept the NewDataCallback the same, as one input parameter is the BSEC instance. In BSEC2 i get an error 100 from BSEC2.
Please let me know what is the problem .
Bsec2 envSensors[2];
for(int i = 0; i < NUMBEROFDEVICES; i ++)
{
//Set multiplexer
if (!envSensors[i].begin(BME68X_I2C_ADDR_LOW, Wire))
{
checkBsecStatus(envSensors[i]);
}
/* Subsribe to the desired BSEC2 outputs */
if (!envSensors[i].updateSubscription(sensorList, ARRAY_LEN(sensorList), BSEC_SAMPLE_RATE_LP))
{
checkBsecStatus(envSensors[i]);
}
/* Whenever new data is available call the newDataCallback function */
envSensors[i].attachCallback(newDataCallback);
envSensors[i].index = i;
Serial.println("BSEC library version " + \
String(envSensors[i].version.major) + "." \
+ String(envSensors[i].version.minor) + "." \
+ String(envSensors[i].version.major_bugfix) + "." \
+ String(envSensors[i].version.minor_bugfix));
}
}
if (!envSensors[i].begin(BME68X_I2C_ADDR_LOW, Wire))
{
checkBsecStatus(envSensors[i]);
}
I checked the Arduino example for x8 board, which has 8 times BME688 and Multiplexer. It seems like the example is reading and processing only 1 BME688 sensor.
Kind Regards
