9 Thermal Protection Application Scenarios
9.1 Pre-configuration
AT^CURC=2,0x8000000000,0x8000000000
Enable the thermal protection
unsolicited indication when the
module is working or in sleep
mode.
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.
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
9.2 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
