Cicada/LoraTile: Light values only update at beginning of sketch

[everhamme]

I am trying to understand why the light values only update once at the beginning of the sketch. For subsequent updates all light values are reported as zero.

Beginning:
Red raw counts = 212
Green raw counts = 173
Blue raw counts = 93
White raw counts = 498
Inferred IR raw counts = 20

Red light power density = 2.21 microWatt/cm^2
Green light power density = 2.34 microWatt/cm^2
Blue light power density = 1.66 microWatt/cm^2

Ambient light intensity = 43.54 lux

Correlated Color Temperature = 6819.09 Kelvin

During subsequent updates

Red raw counts = 0
Green raw counts = 0
Blue raw counts = 0
White raw counts = 0
Inferred IR raw counts = 0

Red light power density = 0.00 microWatt/cm^2
Green light power density = 0.00 microWatt/cm^2
Blue light power density = 0.00 microWatt/cm^2

Ambient light intensity = 0.00 lux

Correlated Color Temperature = nan Kelvin

Sometimes the device needs a bit more time to get the data. You could try adding 5 ms like this: // VEML6040 Data VEML6040.enableVEML6040(IT); // enable VEML6040 sensor delay(ITime + 5); // wait for integration of light sensor data VEML6040.getRGBWdata(RGBWData); // read light sensor data VEML6040.disableVEML6040(IT); // disable VEML6040 sensor
