^SCTM_A: <m>
for battery temperature
URC 2
^SCTM_B: <m>
for module (board) temperature
Command Description
The read command returns the URC presentation mode and information about the current temperature range of
the module. Please note that the Read command does not indicate the temperature range of the battery. The
battery temperature can only be reported by an Unsolicited Result Code.
Select
<n>
to enable or disable the presentation of the URCs. Please note that the setting will not be stored upon
Power Down, i.e. after restart or reset, the default
<n>
=0 will be restored. To benefit from the URCs
<n>
=1 needs
to be selected every time you reboot the GSM engine.
Parameter Description
0 (&F) Presentation of URCs is disabled (except for
<m>
equal to -2 or +2).
1 Presentation of URCs is enabled.
-2 Below lowest temperature limit (causes immediate switch-off)
-1 Below low temperature alert limit
0 Normal operating temperature
1 Above upper temperature alert limit
2 Above uppermost temperature limit (causes immediate switch-off)
Notes
• Please refer to the "Hardware Interface Description" for specifications on critical temperature ranges.
• To avoid damage the module will shut down once the critical temperature is exceeded. The procedure is
equivalent to the power-down initiated with
AT^SMSO
.
• URCs indicating the alert level "1" or "-1" are intended to enable the user to take appropriate precautions,
such as protect the module or battery from exposure to extreme conditions, or save or back up data etc. The
presentation of "1" or "-1" URCs depends on the settings selected with the write command:
If
<n>
=0: Presentation is enabled for 15 s time after the module was switched on. After 15 s operation, the
presentation will be disabled, i.e. no URCs will be generated.
If
<n>
= 1: Presentation of "1" or "-1" URCs is always enabled.
• Level "2" or "-2" URCs are followed by immediate shutdown. The presentation of these URCs is always
enabled, i.e. they will be output even though the factory setting
AT^SCTM
=0 was never changed.
• If the temperature limit is exceeded while an emergency call is in progress the engine continues to measure
the temperature and to deliver alert messages, but deactivates the shutdown functionality. Once the call is
terminated full temperature control will be resumed. If the temperature is still out of range ME switches off
immediately.
