Any example code?

Hi, I tried this, maybe I'm doing it wrong :)

It doesn't get past pc.printf("after reset\n");

Update: I used 

Serial pc(USBTX, USBRX);
ESP8266_WebServer ESP_WS(&pc);

And I see requests on my pc terminal, but it hangs inside functions due to not having a timeout

#include "mbed.h"
#include "ESP8266_WebServer.h"

Serial pc(USBTX, USBRX);
Serial esp(PA_11, PA_12);
ESP8266_WebServer ESP_WS(&esp);


int main()
{
    pc.baud(115200);
    esp.baud(115200);
    wait(0.5);
    
    pc.printf("before reset?");
    ESP_WS.ResetModule();
    pc.printf("after reset\n");
    ESP_WS.Initialize();
    pc.printf("initialized?\n");
    
    while(1) {
        
    }
}

Hi Radu

This library is not quite ready for public consumption yet, and is primarily used in our WiFi Lamp project. It still has a few kinks and quibbles, and thats also why I haven't publicly listed it yet,

Nonetheless, here is a bit of code which should get you started

#include "mbed.h"
#include "ESP8266_WebServer.h"
#include <string>

//#define DEBUG_WIFI

Serial wifiSerial(PA_11,PA_12);
Serial pc(USBTX,USBRX);
ESP8266_WebServer server(&wifiSerial);

void rxint(void) {
    server.rxint();
}

int main() {
    pc.baud(115200);
    wifiSerial.baud(115200);
    wifiSerial.attach(&rxint);
#ifdef DEBUG_WIFI
    server.debugSerial = &pc;
    pc.printf("Debug WiFi Enabled!\r\n");
#endif
    wait_ms(1000);
    
    pc.printf("Hardware Reset WiFi...\r\n");    
    server.ResetModule();
    
    std::string fwVer = server.GetFirmwareVersion();
    pc.printf("ESP Firmware Version: %s\r\n", fwVer.c_str());
    
    pc.printf("Starting Web Server...\r\n");
    server.Initialize();
    pc.printf("Done\r\n");

    int opMode = server.GetOperatingMode();
    pc.printf("Operating Mode: %s(%d)\r\n", opModes[opMode], opMode);
    if( (opMode & OPMODE_STATION) ) {
        pc.printf("Waiting 5 secs for join to WiFi Network...\r\n");
        wait_ms(5000);
        std::string stationMAC = server.GetStationMAC();
        std::string stationIP = server.GetStationIP();
        std::string ssid = server.GetStationSSID();
        pc.printf("Station MAC: %s, Station SSID: %s, Station IP: %s\r\n", stationMAC.c_str(), ssid.c_str(), stationIP.c_str());
    }
    if( (opMode & OPMODE_SOFTAP) ) {
        std::string apMAC = server.GetAPMAC();
        std::string apIP = server.GetAPIP();
        pc.printf("SoftAP MAC: %s, SoftAP IP: %s\r\n", apMAC.c_str(), apIP.c_str());
    }

    while(true) {
        ESP8266_WebRequest* request = server.GetRequest();
        if( request != NULL ) {
            pc.printf("HTTP %s %s\r\n", request->Method.c_str(), request->URI.c_str());
            if( request->URI == "/" || request->URI == "/index.html" ) {
                server.SendReply(request->LinkID, "<html><body>It Works!</body></html>", mimeHTML, 0);
            } else {
                server.Send404Error(request->LinkID);
            }
            pc.printf("\r\nHTTP Reply Sent\r\n");
            delete request;
        }
    }
}

Information

You can uncomment the DEBUG_WIFI define to make the library print out a lot of debugging information.

Warning

This sample requires about 33kb of Flash, and 8kb of RAM. Any hardware with less RAM or Flash will not work.

Hi and thanks, I was reluctant at first to ask, considering it was not public, but I just had to :D I'm packed with a Nucleo F411RE. I'll keep you posted.

Well, as a good news it works.I need to update my firmware to support the new CIPSTA commands

All good. A bit of publicity will force me to bring it up to standard :-)

BTW, I have found this firmware to be quite stable and seems pretty official https://github.com/espressif/esp8266_at

As I and other have found, the recent ESP8266 modules are 9600 buad, there is no auto-baud so you may want to try this setting.

Mine works at 11500 so that was not the issue :)

Hi Paul

A lot of recent ESP8266 modules are very mixed in regards to their baud rate, and I have not been able to determine a definite guide to figuring it out. My own module was first 9600, but when I upgraded it to the latest Espressif AT firmware, it changed to 115200 https://github.com/espressif/esp8266_at
