Setup webrepl : Web upload and download by HTML

• Setup webrepl on esp32

  • >>> import webrepl_setup

    • MicroPython v1.8.6-7-gefd0927 on 2016-11-10; ESP module with ESP8266

    • Type "help()" for more information.

    • >>> import webrepl_setup

    • WebREPL daemon auto-start status: disabled

    • Would you like to (E)nable or (D)isable it running on boot?

    • (Empty line to quit)

    • > E

    • To enable WebREPL, you must set password for it

    • New password: srccodes

    • Confirm password: srccodes

    • Changes will be activated after reboot

  • Would you like to reboot now? (y/n) y

  • Check essid :

• • • MicroPython v1.8.6-7-gefd0927 on 2016-11-10; ESP module with ESP8266

    • Type "help()" for more information.

    • >>> import network;

    • >>> ap = network.WLAN(network.AP_IF);

    • >>> print(ap.config('essid'));

    • MicroPython-d0fa00

    • >>>

• • • Setup ESSID :

      • MicroPython v1.8.6-7-gefd0927 on 2016-11-10; ESP module with ESP8266

      • Type "help()" for more information.

      • >>> import network;

      • >>> ap = network.WLAN(network.AP_IF);

      • >>> ap.active(True);

      • >>> ap.config(essid='MyESP8266', authmode=network.AUTH_WPA_WPA2_PSK, password='mypassword');

      • >>> print(ap.config('essid'));

      • MyESP8266

      • >>>

    • Start and Open webrepl web

      • Install WebREPL client and run program over WIFI

        1. Download the WebREPL client from https://github.com/micropython/webrepl/archive/master.zip and unzip the same.

        2. Disconnect USB to Serial converter from computer.

        3. Connect computer to the WIFI access point of ESP8266.

        4. open webrepl.html in folder
