- Added readSerial(Stream &stream) method to allow reading from any Stream-compatible transport. - Introduced readChar(char inChar) method for processing individual characters. - Updated command matching logic to enhance debugging output. - Improved buffer handling and command execution flow. Enhance platformio.ini for better compatibility and added libraries - Added NimBLE-Arduino and WebSockets libraries for BLE and WiFi support. - Updated upload and monitor ports for better compatibility with macOS. Integrate WiFi and BLE protocol interfaces - Implemented startWebInterface() to initialize WiFi protocol alongside existing web server. - Added BLE support with a new EggBot BLE Serial Protocol for command handling over BLE. - Created WebSocket server for WiFi communication, maintaining compatibility with existing command protocols. Refactor command handling in Functions.cpp - Replaced direct Serial.print calls with protocolWrite for consistent output handling. - Updated command registration to use a lambda function for better readability and maintainability. Add documentation for EggBot protocols - Created separate markdown files for BLE, WiFi, and Serial protocols detailing command structures and usage. - Provided examples of command transactions for better developer guidance. Implement BLE and WiFi protocol handling in respective source files - Developed BLE_Interface.cpp for managing BLE connections and data transmission. - Created WiFi_Protocol.cpp for handling WebSocket communication and data reception.

# EggBot WiFi Serial Protocol
|
|
|
|
## Scope
|
|
This transport exposes the same EggBot command protocol as serial, but over WiFi/WebSocket.
|
|
|
|
- Protocol commands and responses are unchanged.
|
|
- Framing is unchanged (`\r` command terminator, `\r\n` response lines).
|
|
|
|
## Transport Profile
|
|
- Protocol endpoint: `ws://<eggs-esp32-ip>:1337/`
|
|
- WebSocket message type: text or binary frames accepted
|
|
- Payload: ASCII command bytes
|
|
|
|
## Data Model
|
|
- Host writes command bytes to the WebSocket.
|
|
- Firmware parses incoming bytes with the same EggBot parser used for USB serial and BLE.
|
|
- Firmware sends responses as WebSocket text messages.
|
|
- Hosts must treat inbound data as a stream and parse lines by `\r\n`.
|
|
|
|
## Compatibility Rules
|
|
- A WiFi client must send commands exactly as serial hosts do.
|
|
- Each command must end with `\r`.
|
|
- Data-returning commands (`QP`, `QB`, `QN`, `QL`) return a value line before final status (`OK\r\n`).
|
|
- Unknown/invalid command format returns `unknown CMD\r\n`.
|
|
|
|
## Example WiFi Transactions
|
|
Version query:
|
|
- Send: `v\r`
|
|
- Receive: `EBBv13_and_above Protocol emulated by Eggduino-Firmware V1.6a\r\n`
|
|
|
|
Move command:
|
|
- Send: `SM,100,0,200\r`
|
|
- Receive: `OK\r\n`
|
|
|
|
Query layer:
|
|
- Send: `QL\r`
|
|
- Receive: `<layer>\r\n`
|
|
- Receive: `OK\r\n`
|
|
|
|
## Operational Notes
|
|
- The WiFi protocol endpoint is started only when ESP32 station WiFi is connected.
|
|
- Incoming WiFi bytes are queued and parsed in the main loop.
|
|
- If the WiFi RX queue overruns, excess bytes are dropped and a log entry is generated.
|
|
- WiFi transport is single active client: first connected sender is accepted until disconnect.
|
|
- USB serial, BLE, and WiFi can coexist; responses are routed to the transport that received each command.
