CUSTOM AT COMMANDS
155 HSPA+ AT Commands Reference Guide
0 ‐ No action
1 ‐ Automatic shut‐down when the temperature is beyond the extreme bounds
2 ‐ 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.
4 ‐ 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_time> <hyst_time> ‐ hysteresis time: all the actions happen only if the extreme or
operating bounds are maintained at least for this period. This parameter is
needed and required if <action> is not zero.
0..255 ‐ time in seconds
<GPIO> GPIO number. valid range is “any output pin” (see “Hardware User’s Guide”). This
parameter is needed and required only if <action>=4 is required.
Notes
ƒ The URC presentation mode <urcmode> is related to the current AT instance only (see +cmux); last
<urcmode> settings are saved for every instance as extended profile parameters, thus it is possible to
restore them either if the multiplexer control channel is released and set up, back and forth.
ƒ Last <action>, <hyst_time> and <GPIO> settings are saved in NVM too, but they are not related to the
current CMUX instance only (see +cmux).
ƒ The following table lists typical temperature bounds
Extreme Temperature Lower Bound ‐30°C
Operating Temperature Lower Bound ‐10°C
Operating Temperature Upper Bound 55°C
Extreme Temperature Upper Bound 80°C
General Purpose Input/Output Pin Control #GPIO
Execute command sets the value of the general purpose output pin GPIO<pin> according to <dir> and <mode>
parameter.
Not all configurations for the three parameters are valid.
Read command reports the read direction and value of all GPIO pins, in the format:
#GPIO: <dir>,<stat>[<CR><LF>#GPIO: <dir>,<stat>[…]]
where the sections that follow describe values for <dir> and <stat>.
Test command reports the supported range of values of the command parameters <pin>, <mode> and <dir>.
