    Cheap Arduino WiFi Shield With ESP8266

    Look to my last entry. :) This will help you to solve this issue.

    Connect your WLAN ESP01 like to following points:3,3V -> 3,3VGND->GNDRX->D0/RXTX->D1/TXENT->3,3VYou don't need electrical parts if you use uno. If you use mini 3,3V are not stable on current and will stop working. Then you need electrical parts with separate 5V to 3,3V step down. Please don't use 5V you can brick your ESP01 for ever. Load BareMinimum and save into arduinoOpen Serial Monitor and set down below right corner dropdown to Both NL & CR 115200 baud.Now type in command line AT you will get response OK. If you get OK your ESP01 is well and waits for next command. Now type AT+GMR you will get the software version and much more. If this is fine type AT+UART_DEF=9600,8,1,0,0This will set your ESP01 to 9600 baud. You will get OK. Thereafter you get no response. Se...

If you get OK its all fine and you can use ESP01 on 9600 software serial now.More information i use WiFiesp lib. Via examples->WiFiesp->test->espdebug you can load a test script into your arduino for testing software AT commands. If this will work you have done the job!

    Arduino Uno and all versions below can't handle high baut rates. The EPS01 must get an AT command to change this down to 9600 with an AT command i post this in my comment. There after communication with the chip and scripts are working. Only Arduino Mega work with 115000.

    In the meanwhile i have found why 115200 doesn't work, cause arduino can't simulate 115200 well. That's all.

    Hello together!For all people out there i have some news. I get my ESP01 with baudrate 115200. Arduino don't like this baudrate and you will get not supported firmware. You must change in debug script serial1 and serial. Then you can speak with your ESP01.If you typ AT you get some error and firmware read out is totally bad. Now send your ESP01 this command: AT+UART_DEF=9600,8,1,0,0Thereafter change serial and serial1 again and voilat your ESP01 work as aspected. It's totally recommand that you change the boudrate down to 9600 via AT Command. And then your ESP01 will work fine. :)
