CUSTOM AT COMMANDS
AT Commands for EV-DO-EV3 Modems
104
0 - Normal temperature
1 - Operating temperature upper bound, +55°C.
2 - Extreme temperature upper bound, +80°C.
Notes:
Threshold levels are for the radio only.
Threshold temperatures are ±2°C .
Refer to your User Guide or Developer Guide for operating temperature ranges
for your device.
<value>
Actual temperature in Celsius degrees
The following parameters have meaning of <mod>=0.
<urcmode> URC presentation mode.
0 Disables temperature monitor URC presentation.
1 Enables temperature monitor URC presentation, when the module internal
temperature reaches either operating or extreme temperatures.
For extreme levels, the URC and action be applied as:
Hysteresis time, URC message, 5 sec delay, action.
The unsolicited message is in the format:
#TEMPMEAS: <level>,<value>
Where <level> and <value> are as before.
<action> Sum of integers, each representing the action to be done when the module
internal temperature reaches either operating or extreme levels (default is 1). If
<action> is not zero, it is mandatory to set the <hyst_time> parameter too.
0 00 - No action. C2 Default: 0
1 01- Automatic shut-down when the temperature is beyond the extreme bounds.
EV3 Default: 1.
2 10 - RF TX circuits automatically disabled (using +CFUN=2) when operating
temperature bounds are reached. When the temperature is back to normal, the
module is brought back to the previous state, before RF TX disabled (10).
4 100 - The output pin <GPIO> is tied HIGH when operating temperature bounds
are reached; when the temperature is back to normal the output pin <GPIO> is
tied LOW. If this <action> is required, it is mandatory to set the <GPIO> parameter
too.
<hyst> Hysteresis time: all the actions happen only if the extreme or operating bounds
are maintained at least for this period. This parameter is required if <action> is
not zero.
Note: <action> can assume values from
0 - 255 Time in seconds. Default: 45.
<GPIO> GPIO number. Valid range is any output pin. This parameter is required only if
<action>=4 is enabled.
Note: If <GPIO> is specified <action> shall assume values from 4-7.
Notes
The last <action>, <hyst_time> and <GPIO> settings are global parameters saved in non-volatile memory.
The automatic power off is deferred for emergency calls.
