Fastory Reset

You may need to reset the module to factory settings, if you forget the AP SSID and password. To do this, Connect the board to power, short IO13 and IO15 with a tweezer or a screwdriver, then press the reset button, and release the reset button. You will see the big bright LED blink twice fast. Then you can release the tweezer or screwdriver, and press the reset button again. The module will reset to factory settings.

Example

Here's an example connecting to Wi-Fi with ssid: SunFounder and password: sunfounder. Then echos what it reads from websocket client. [tx] is what you need to send over UART, and [rx] is what you get from rx. Under [rx], [DEBUG] will only appear in debug mode, and without it, is what you receive for your code.

[tx] SET+SSIDMakerStarsHall  // Set ssid to MakerStarsHall
[rx] [DEBUG] RX Receive: SET+SSIDMakerStarsHall
[rx] [DEBUG] Set SSID: SunFounder
[rx] [OK]

[tx] SET+PSKsunfounder   // Set password to sunfounder
[rx] [DEBUG] RX Receive: SET+PSKsunfounder
[rx] [DEBUG] Set password: sunfounder
[rx] [OK]

[tx] SET+MODE1   // Set mode to STA
[rx] [DEBUG] RX Receive: SET+MODE1
[rx] [DEBUG] Set mode: 1
[rx] [OK]

[tx] SET+MODE2   // Set mode to AP
[rx] [DEBUG] RX Receive: SET+MODE1
[rx] [DEBUG] Set mode: 1
[rx] [OK]

[tx] SET+PORT8765   // Set websocket server port to 8765
[rx] [DEBUG] RX Receive: SET+PORT8765
[rx] [DEBUG] Set port: 8765
[rx] [OK]

[tx] SET+START   // Start connecting and start websocket server
[rx] [DEBUG] Connecting  // it will automaticaly try to connect to Wi-Fi as you fill in both ssid and password
[rx] [DEBUG] WiFi connected
[rx] [DEBUG] IP address:
[rx] 192.168.43.145
[rx] [DEBUG] Is server live? 1
[rx] [DEBUG] Websocker on!    // Now Websocket is on!

[rx] [DEBUG] RX Receive: Hello    // Websocket receives a hello.
[tx] WS+Hello    // Send out a Hello back to the Websocket client.
