7.11 AT^SCTM Set critical operating temperature presentation mode or
query temperature
This command can be used to monitor the temperature of the module.
CAUTION: During the first 15 seconds after start-up, the module operates in an automatic report
mode: URCs can be always displayed regardless of the selected mode <n>.
Test command
AT^SCTM=?
Response
If parameter <p> = 0:
^SCTM: (list of supported <n>s) OK
If parameter <p> = 1:
^SCTM: (list of supported <n>s),(range of <temp> in degrees Celsius) OK
Parameters
See write command
Read command
AT^SCTM?
TA returns the following parameters
· URC presentation mode
· Information about the current temperature range of the module.
Please note that the Read command does not indicate the temperature range
of the battery. This value can only be reported by an Unsolicited Result Code.
· The board temperature in degrees Celsius if <p>=1.
Response
If parameter <p> = 0:
^SCTM: <n>, <m> OK
If parameter <p> = 1:
^SCTM: <n>, <m>, <temp>OK
Parameters
<n> See Write command.
<m> -2 Low temperature limit is exceeded (causes switch-off)
-1 Board is close to low temperature limit
0 Normal operating temperature
1 Board is close to high temperature limit
2 High temperature limit is exceeded (causes switch-off)
<temp> Current board temperature in degrees Celsius. The value is comprised
between lowest and upper temperature limits.
Write command
AT^SCTM=<n>
[,p>]
Response
OK
Parameters
<n> 0 Suppress URCs (except for <m> equal to –2 or +2).
1 Enable presentation of URCs.
<p> 0 Suppress output of <temp> in Test and Read command.
1 Enable presentation of <temp> in Test and Read command.
The settings will not be stored upon Power Down, i.e. after restart or reset, the de-
faults <n>=0 and <p>=0 will be restored. To benefit from the URCs <n>=1 needs to
be selected every time you reboot the module. The same applies to <p>=1.
