15.2.1Description
Configures the GPIOs pins as input, output or to handle a custom function. When the GPIOs pins are configured
as output pin, it is possible to set the value.
The test command provides the list of the supported GPIOs, the supported functions and the status of all the
GPIOs.
Not all the GPIO functions can be assigned to each GPIO pin. If the configuration is not allowed, an error
result code will be returned (error result code 1502 - "+CME ERROR: Select GPIO mode error").
The following custom functions cannot be simultaneously configured on 2 GPIOs:
Network status indication
Ring indication
GNSS supply enable
GNSS data ready
GNSS RTC sharing
