Get Current Temperature (72h)
The Get Current Temperature command returns the current board component
temperature on the module in degrees Celsius as a signed 8-bit integer. This information
can be used to determine if the module is exceeding its recommended operating
temperature range. If the returned value exceeds the values specified in the table below
an effort should be made to reduce the ambient temperature of the module or reduce the
module’s duty cycle.
Note
In M5e Firmware release v1.5.1 the temperature threshold value changed.
This change is due to a value calculation change and not a change in the
actual temperature threshold. The previous values returned were in
uncalibrated “units”, not actual degress Celcius.
The command is generated as follows:
The response returns a signed 8-bit integer in degrees Celsius, 0x24 = 36
