9 Thermal Protection Application Scenarios

9.1 Pre-configuration

Command	Description

AT^CURC=2,0x8000000000,0x8000000000	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.

9.1.1 Troubleshooting

None

9.2Thermal 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
