Add Indoor Air Quality (IAQ) index from BME680 #446

t-pi · 2022-02-12T22:20:14Z

Switch from BME680 to BSEC driver to compute Indoor Air Quality (IAQ) index.
Log iaq data to serial console
Added BLE service for environmental data incl. IAQ

Hmm, the CI setup can't find the local file from the BSEC library:
"config\generic_33v_3s_4d\bsec_iaq.txt: No such file or directory"

despite the file being there in the library folder structure on my pio lib folder.

Can you please check the CI, if there is some configuration preventing to link to lib files?
Thanks!

Not sure where the problem is. Can you link to it?

multigeiger/ble.cpp

+        txBufferEnv[0] = iaq & 0xFF;
+        txBufferEnv[1] = (iaq >> 8) & 0xFF;
+        bleEnvIAQChr->setValue(txBufferEnv, 2);


can't one use setValue<int> here also?

"unsupported THP sensor" maybe?

  if (type_thp == 280) {
    *temperature = bme280.readTemperature();
    *humidity = bme280.readHumidity();
    *pressure = bme280.readPressure();
+    *iaq = 0;


so 0 is outside the value range for sure? as it is a int, we could also use -1.
