ESP8266 module allows to use RemoteXY with mcu device for Wi-Fi. The source code of GUI can be download for the Arduino IDE and Program. To use the ESP8266 module to select this module in the properties configuration settings is below given.
Access point mode of ESP8266 configures the module as an access point and allows to connect Arduino directly to this point. The access point is available to connect to it from smartphone or tablet within a radius of availability of the radio signal. This connection mode can be used in the far away place where there is no computer networks and the Internet.
To configure this mode in the configuration properties of editor need to select the type of connection “Wi-Fi access point.”
The module is connected to the microcontroller board via serial interface. You can choose to use software serial or hardware serial. Module connection option is selected in the module interface settings of editor. The module is controlled via AT commands.
Power of module can be provided from the DC-DC of Arduino board to 3.3V. Some boards, such as Arduino Nano can not provide sufficient power to output 3.3V, in this case, you need a separate power supply.
Connection via Software Serial. ESP8266 default configured to 115200 baud. Connection via Hardware Serial
ESP8266 must be to pre-configured to work at the same speed as the Arduino. The baud rate setting of module can be made via AT commands.
