Syntax:
This command sets the default GPIO’s configuration (input or output) after reset, and each GPIO default
value (if set as an output) after reset.
Notes:
<GpioDir> Bit table parameter indicating each GPIO direction.
<GpioVal> Bit table parameter indicating each output-configured GPIO value (each bit gives the

change the state of the GPIO using this command.
This command is allowed only on a GPIO not allocated by the Open-AT embedded application or
for bus operations.
When UART is activated, GPIOs 0 and 5, GPO2 and GPI are not available anymore. When you
try to do writable or readable operations on these I/O, CME ERROR: 3 will be returned. This
applies for modems running AT X50 software and supporting the multi-UART feature.
When the BT chip is switched on, the GPIO5 is not available anymore. It is not possible to
