ESP32 to WiFi via Access Point

This simple example provides

• Opening of an access point (AP) with the name ESP32_Server
• Under the static IP 192.168.1.1 you will be asked to type in your ssid name and wifi psw
• After successfull connection to the AP the RGB LED on you Wroover-Kit will light up
• Your ESP32 is now connected to WiFi (IP is not static any more)

Use this as a template for your projects it can be very handy in various ways ;). Please let me know if you have anything to improve or commit.

Cheers

Example ESP32 to WiFi Connection

After flashing you will see this on your board

and this in the consol

...
I (431) ESP32_Server: Starting server on port: '80'
I (431) ESP32_Server: wifi_event_handler wifi_event_handler wifi_event_handler
I (441) ESP32_Server: Registering URI handlers

After connection successfully to ssid:ESP32_Server and psw:ESP32_Server

...
I (133931) ESP32_Server: station 9c:b6:d0:e7:30:0f join, AID=1
I (133931) ESP32_Server: wifi_event_handler wifi_event_handler wifi_event_handler
I (133991) tcpip_adapter: softAP assign IP to station,IP is: <IP of your AP>

After typing 192.168.1.1 into firefox and providing your WiFi AP ssid and psw

...
I (330) wifi: mode : sta (30:ae:a4:ef:4a:60)
I (1060) wifi: new:<6,1>, old:<1,0>, ap:<255,255>, sta:<6,1>, prof:1
I (2040) wifi: state: init -> auth (b0)
I (2050) wifi: state: auth -> assoc (0)
I (2060) wifi: state: assoc -> run (10)
I (2330) wifi: connected with <Name of your WiFi AP>, channel 6, bssid = <bssid>
I (2330) wifi: pm start, type: 1

I (3210) tcpip_adapter: sta ip: <new IP of ESP32>, mask: <mask>, gw: <gw ip>
I (3210) ESP32_Server: SYSTEM_EVENT_STA_GOT_IP
I (3210) ESP32_Server: Login Success
I (3220) ESP32_Server: Starting server on port: '80'
I (3220) ESP32_Server: Registering URI handlers

You are no connected to the internet with your ESP32 and the RGB LED is lightening up ;). The AP ESP32_Server will not exist anymore.

Note:

Only one device at a time can be connected to the ESP32_Server AP for safety. If you type in the wrong psw the ESP32_Server Server will stay up.
