:
AT commands serial port mode: the V24 pins are
controlled by the serial port device driver
1
:
GPIO mode: output pins can be managed through the
AT#V24 command only
2
:
GPIO Kernel mode: output pins directly controlled by
kernel GPIO driver
<save>
integer
N/A
Save V24 pin configuration
Values:
0
:
Pin configuration is not saved
1
:
Pin configuration is saved
If <mode> is set to 2, output pins directly can't be controlled by
#V24 command, <save> parameter should be set to 1, module
must be reboot, the pins configuration is applied next power cycle
and pins directly controlled by kernel GPIO driver.
If <save> parameter is omitted, the value of <mode> is changed as
default mode from next power cycle.
Changing V24 pins configuration may affect the cellular module
functionality set through +CFUN.
If <pin>=4 is set to <mode>=2 or 1, <save> parameter should be set
to 1, module must be reboot, pin configuration is applied next
power cycle. Changing from <mode>=2 or 1 to <mode>=0, module
must be reboot.
If <pin>=1, 5 ,6 or 7 is set to <mode>=2 or 1, <save> parameter
should be set to 1, module must be reboot, pin configuration is
applied next power cycle. The unset pins of 4 pins don't work as
UART pin. Changing from <mode>=2 or 1 to <mode>=0, module
must be reboot.
