184.108.40.206. Temperature Calculation for the Internal Temperature Sensor
To convert the returned value into decimal, use two's complement operation on the signed integer portion. Then, add the decimal number to the unsigned 8-bit fraction ( ). For example, if the returned value is 0xFFFFE1C0, the temperature value is -30.25°C.
The unsigned 8-bit fraction is always zero for the temperature values returned by the transceiver tiles.
