Thermal Protection Application Scenarios
9.1 Pre-configuration
Command
Description
^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 101°C, the module works normally.
When the module's temperature is higher than 101°C, the module enables
thermal protection: turns off its RF transmission and presents the
^THERM: 1
indication. When the module's temperature is higher than 107°C, the module will
turn off after 15 seconds. When the module's temperature is lower than 93°C,
the module disables thermal protection: turns on its RF transmission, and
presents the
^THERM: 0
indication.
