0 - dummy value
1 - dummy value
 wait for response OK
Remember that the alternate function places the GPIO5 pin always in OUTPUT direction.
The #GPIO5 direction setting is saved and will be kept after a power off.
The saving can be applied only for the alternate mode.
For example:
1- Let us assume you want to set GPIO5 pin as RFTXMON OUTPUT:
command
AT#GPIO=5,0,2<cr>
response:
OK
In this case, the GPIO5 pin was successfully put in RFTXMON output direction.
When you set the GPIO6 pin as alarm output function, the pin reports the alarm state
following the +CALA settings. To set the pin in alternate function you must specify also a
dummy value for the pin state:
 send command AT#GPIO=6,<dummy_value>,2<cr>
where:
<value> is a dummy value can be either:
0 - dummy value
1 - dummy value
Remember that the alternate function places the GPIO6 pin always in OUTPUT direction and
since the GPIO6 pin value is controlled by the internal software, the corresponding function
(+CALA) must be setup properly.
The #GPIO6 direction setting is saved and will be kept after a power off.
