(5) Use of GPIO10
If you click the GPIO10 button twice consecutively, the WizFi210 is restored to factory
default. And if you click the GPIO10 button three times consecutively, the WizFi210 is
restored to factory default and will change to ad hoc mode to configure the WizFi210 via
WiFi. (IP:192.168.1.254/Subnet:255.255.255.0/Gateway:192.168.1.1)
Figure 9. Factory Default and ad hoc mode
As previously described, GPIO10 is used for data/command mode transition by applying
“AT+XEHT=1” command. But there should be no UART input in 300mS before and after
sending signal to GPIO10 for mode transition time and buffer processing time.
