FRC_Temperature = 0x80
Collects bytes. The resulting byte equals the temperature value read by the getTemperature IQRF OS function. If the resulting temperature is 0°C, which would normally equal 0, then a fixed value 0x7F is returned instead. This value substitution makes it possible to distinguish between devices reporting 0°C and devices not reporting at all. The device would normally never return a temperature corresponding to the value 0x7F because +127°C is out of the working temperature range.
