With addition of Struct, propane values somehow unusually low #4

It appears that with the addition of the sanity check isValid() the propane value changes. I'm not sure why. Getting all gas values rapidly, like below gives values as before:

gasNH3.value = gas.measure_NH3();<BR> gasCO.value = gas.measure_CO(); gasNO2.value = gas.measure_NO2(); gasC3H8.value = gas.measure_C3H8(); gasC4H10.value = gas.measure_C4H10(); gasCH4.value = gas.measure_CH4(); gasH2.value = gas.measure_H2(); gasC2H5OH.value = gas.measure_C2H5OH(); return;

Probably need to separate out into more functions:

getData()

encodeData()

transmitData()

Grouping all gas.measure_XXX() together did the trick. Separated all three functions as mentioned.
