ESP8266pro Arduino library - is easy to use and powerfull WiFi Module wrapper. Now it implements all major module features, break code into the classes, and don't require any AT commands knowledge.
ESP8266pro wifi(espSerial, Serial); // Serial, DebugSerial
// Initialize module
wifi.begin();
// Connect to WiFi network
wifi.stationConnect(ssid, password);
Serial.println(wifi.stationIP());
// Send request
ESP8266proClient con(wifi);
con.connectTcp("37.59.251.26", 80);
con.send("GET / HTTP/1.0\r\nHost: simple.anakod.ru\r\n\r\n");
con.waitResponse();
con.close(); // Completed!// Create access point
wifi.accessPointStart("ESP_AP", "123456789");
// Get AP IP address
String ip = wifi.accessPointIP();
Serial.println(ip);
delay(10000);
// Quit from Access Point mode
wifi.accessPointStop();ESP8266proServer server(wifi, onClientRequest);
// Start server on port 80
server.start(80);void loop()
{
// Process incoming requests
server.processRequests();
}
void onClientRequest(ESP8266proConnection* connection,
char* buffer, int length, boolean completed)
{
if (completed)
{
connection->send("HTTP/1.0 200 OK\r\n\r\n");
connection->send("Hi from ESP8266pro!");
connection->close();
}
}During development I have been used SoftwareSerial library, and connect ESP8266 to digital pins 9 and 10 on Arduino board. But you can use HardwareSerial instead this, or additional hardware serial port (if you have). No any limitation here.
ESP8266pro wifi(/*ESP8266_SERIAL*/, /*OPTIONAL_DEBUG_SERIAL*/);Extract all files to <Your Arduino folder>\libraries\ESP8266pro directory. Restart Arduino IDE and open examples from list.
- Update ESP8266 firmware to lastest version before using this library (at least AT v0.20)
- Verify, what WiFi module UART works on 9600 speed (also you can choose different speed, but don't forget about software serial limitations)
- Increase _SS_MAX_RX_BUFF in Arduino SoftwareSerial.h to prevent data loss (because by default, Arduino has very small buffers for software and hardware serials). I recommend size of 256 bytes for that:
//In SoftwareSerial.h:
#define _SS_MAX_RX_BUFF 256If you using HardwareSerial instead of software, you should update SERIAL_BUFFER_SIZE constant in HardwareSerial.cpp.
