This is a firmware read convert uart command and create a websocket server. It's originally for Arduino or Raspberry Pi Pico to connect to SunFounder Controller. Send command and data over UART in boardrate 115200

SET+CAMERA_MODE: set Camera pixel format, AI = 0, Stream = 1, Both = 2. AI need RGB565 format, Stream need JPEG format. In Stream-Only mode, camera output JPEG format directly, makes fps higher. In AI-only camera output RGB565, and doestn't need to convert to JPEG and stream, makes fps a little bit higher to 3 fps. In Both mode, camera output RGB565 format for AI than convert to JPEG for stream, makes fps low to 2 fps.

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.
