The module has two ways to work:
(i) mobile phone directly mounted on the WIFI module;
(ii) mobile phone and WIFI module also carried on the router.
Open environment, the mobile phone mounted on the WIFI module when the maximum transmission distance of 400m.
When the WiFI module and mobile phone at the same time carried on the router when the transmission distance according to the router?s signal weakly;
When cell phone equipped with WiFi module sends commands in the following order:
(The default baud rate 115200)
AT CWMODE=2, namely AP mode is selected.
AT RST, reset.
AT CIPMUX=1, open multiple connections.
AT CIPSERVER=1,8080, configure the TCP server, set the port.
AT CIOBAUD=9600 set the baud rate to 9600. (working in relays to control the baud rate 9600).
AT CIFSR to view the AP mode IP address, such as the APIP, ?192.168.4.1?.
Cell phone WIFI signal connection name starts with AI-THINKER or ESP8266.
In the ?TCP connection? address and port into the APP, such as 192.168.4.1 and 8080.
Click on the grey box relays can be controlled.
