Cooling down overheating

Postby drlynass » Sun Oct 20, 2019 8:52 am

I get a cooling down message on the serial Monitor after about 15minutes. The ambient temperature is 20 degrees. Anyone know why I am overheating?

This is determined by the temperature reported by the MEMS chip which reflect the device internal temperature. Try reducing data rate. This happens when cellular signal is weak and the cellular module increases its power consumption. Alternatively, this can be improved by having an external cellular antenna.
