15.3.1 Description
Reads the current value of the specified GPIO pin, no matter whether it is configured as input or output (see
the
AT command to define the GPIO function). The parameters range is shown in the information
text response to the test command.

15.3.3 Defined values
Parameter
Type
Description
<gpio_id>
Number
GPIO pin identifier: pin number
for the available GPIO pins, their mapping and factory-
programmed values on different u-blox cellular modules series and version.
<gpio_val>
Number
GPIO value. Allowed values are 0 and 1.
15.3.4 Notes
• The command works only if the parameter <gpio_mode> of the
AT command is set to 0 or 1.
