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 +UGPIOC AT command to define the GPIO function). The parameters range is shown in the information
text response to the test command.
15.3.2Syntax
Type Syntax Response Example
Set AT+UGPIOR=<gpio_id> +UGPIOR: <gpio_id>,<gpio_val>
OK
AT+UGPIOR=20
+UGPIOR: 20,0
OK
Test AT+UGPIOR=? +UGPIOR: (list of supported <gpio_
id>s)
OK
+UGPIOR: (20, 21)
OK
15.3.3Defined values
Parameter Type Description
<gpio_id> Number GPIO pin identifier: pin number
See the GPIO mapping 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 +UGPIOC AT command is set to 0 or 1.
