Enable the thermal protection
unsolicited indication when the
module is working or in sleep
mode.
OK
^THERM: 1
When the temperature is higher
than the temperature protection
threshold, the module enables
thermal protection: The module
turns off its RF and reports to the
host.
^THERM: 0
When the temperature is lower than
the temperature protection
hysteresis threshold, the module
disables thermal protection: turns
on its RF and reports to the host.

None
9.2 Thermal Protection Process
When the module's temperature is lower than 99°C , the module works normally.
When the module's temperature is higher than 99°C , the module enables
thermal protection: turns off its RF transmission and presents the ^THERM: 1
indication. When the module's temperature is lower than 85°C , the module
