If the reading is greater than 5 °C above the ambient temperature, we recommend either de-rating
the maximum ambient temperature or implementing heat mitigating measures; for example, reduce
transmission frequency and duration, enter sleep mode more frequently, or improve airflow.
Addressing heat issues will help to ensure long term device reliability.
