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
posted by 12 Jan 2015All 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.
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
