AT#GPIO=3,2
response:
#GPIO: 0,1
OK
In this case, the GPIO3 pin was set in input direction and its status has been measured to be HIGH.
2- Let's assume you want to query the GPIO4 pin for its status:
command:
AT#GPIO=4,2
response:
#GPIO: 1,0
OK
In this case, the GPIO4 pin was set in output direction and its status is LOW.
3- Let's assume you want to query the GPIO6 pin for its status:
command:
AT#GPIO=6,2
response:
#GPIO: 2,0
OK
In this case, the GPIO6 pin was set in "alternate function" direction and therefore works as alarm
output. The reported status = LOW has no meaning.
3.6.2.2 Setting GPIO pin output status
To set the pin status (when pin is set as OUTPUT):
• Send command
AT#GPIO=,,1
where:
is the GPIO pin number at which the command applies:
1 – GPIO1 10 – GPIO10
2 – GPIO2 11 – GPIO11
3 – GPIO3 12 – GPIO12
4 – GPIO4 13 – GPIO13
5 – GPIO5 14 – GPIO14
6 – GPIO6 15 – GPIO15
7 – GPIO7 16 – GPIO16
8 – GPIO8 17 – GPIO17
9 – GPIO9 18 – GPIO18
is the pin value to be set and can be:
0 – LOW
1 – HIGH
• wait for response
