AT+HWGPIOMODE
This will set the mode for the specified GPIO pin (input, output, etc.).
Codebase Revision: 0.3.0
Parameters: This command one or two values (comma-separated in the case of two parameters being used):
The pin number
The new GPIO mode, where:
0 = Input
1 = Output
2 = Input with pullup enabled
3 = Input with pulldown enabled
Output: If a single parameters is passed (the GPIO pin number) the current pin mode will be returned.
# Configure pin 14 as an output
AT+HWGPIOMODE=14,0
OK
# Get the current mode for pin 14
AT+HWPGIOMODE=14
0
OK
make use of a reserved pin number an 'ERROR' response will be generated.

Some pins are reserved for specific functions on Bluefruit modules and can not be used as GPIO. If you try to
make use of a reserved pin number an 'ERROR' response will be generated.
