8 AT command

AT+SYSIOSETCFG- set IO working mode
AT+SYSIOSETCFG=<pin>,<mode>,<pull-up>
Response：
1
OK
AT+SYSIOSETCFG=12,3,1 //set GPIO12 working at GPIO mode
Note：E103-W02 has GPIO4\GPIO5\GPIO12\GPIO13\GPIO14 available for user.
AT+SYSIOGETCFG-inquiry IO working mode
AT+SYSIOGETCFG=<pin>
Response：
2
+SYSIOGETCFG:<pin>, <mode>, <pull-up>
OK
For example：AT+SYSIOGETCFG=4
AT+SYSGPIODIR-set GPIO working as input and output
AT+SYSGPIODIR=<pin>,<dir>
Response：
• When succeed，return
OK
• if IO pins are not in GPIO
3
NOT GPIO MODE！
ERROR
For example：
AT+SYSIOSETCFG=12,3,1 //set GPIO12 working at GPIO mode
AT+SYSGPIODIR=12,0 //set GPIO12 as input
AT+SYSGPIOWRITE-set GPIO output level
AT+SYSGPIOWRITE=<pin>, <level>
Response：
• When succeed，return
OK
• if IO pins are not in output
NOT OUTPUT！
4
ERROR
For example：
AT+SYSIOSETCFG=12,3,1 //set GPIO12 working at GPIO mode
AT+SYSGPIODIR=12,1 //set GPIO12 as output
AT+SYSGPIOWRITE=12,1 //set GPIO12 outputting high level
AT+SYSGPIOREAD- read GPIO communication level
