2- Let's assume you want to query the GPIO4 pin for its status:
command:
AT#GPIO=4,2<cr>
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<cr>
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=<pin>,<value>,1<cr>
where:
<pin> is the GPIO pin number at which the command applies:
7 – GPIO7
2 – GPIO2 8 – GPIO8
3 – GPIO3 9 – GPIO9
4 – GPIO4 10 – GPIO10
5 – GPIO5 11 – GPIO11
6 – GPIO6 12 – GPIO12
13 – GPIO13
<value> is the pin value to be set and can be:
0 – LOW
1 – HIGH
•
wait for response
OK
For example:
1- Let's assume you want to set the GPIO3 pin HIGH:
command:
AT#GPIO=3,1,1<cr>
response:
OK
