This pull request refactors the AT command handling system to use structured AtCommand objects throughout the firmware, improving message consistency and extensibility. The main changes include updating how commands and responses are parsed, compiled, and dispatched, and modifying message types to carry richer information. Handler traits and implementations are also updated to work with the new command structure.

AT Command Message Refactor:

• Changed the Msg enum in message_type.rs to use structured variants (AtRxLine, AtCmdOutput, Done, Err, ErrWOCommand, RgbWithValue, FreqWithValue, etc.), replacing the previous MsgDirection and raw string-based messaging. This enables passing full AtCommand objects and IDs, improving clarity and extensibility.

• Updated the AT command parsing logic in command.rs to extract and store a command ID as part of the AtCommand struct, and refactored the compile method to include the ID in the output. Helper functions (get_empty_id, compile_at_done, compile_at_error) were added/modified to support the new message format. [1] [2] [3] [4] [5] [6] [7]

Handler and Dispatcher Updates:

• Refactored the AtHandler trait and all handler implementations (freq_handler.rs, setrgb_handler.rs, version_handler.rs, fwupdate_handler.rs, reset_handler.rs) to accept a full AtCommand object instead of separate parameters and query flags, simplifying handler logic and enabling richer command handling. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12]

• Updated the AtDispatcher to pass the full AtCommand to handlers, aligning with the new trait signature and message format.

Task and Message Flow Changes:

• Refactored the main AT task loop in at_task.rs to handle the new message variants, including proper compilation and routing of responses using IDs and structured commands. Added support for new message types such as SetDdsAvailable. [1] [2]

DDS and RGB Command Handling:

• Updated DDS and RGB command tasks to use full AtCommand objects in their message passing, enabling more flexible and consistent handling of command data. [1] [2] [3]

These changes collectively make the AT command handling system more robust and easier to maintain by using structured data instead of raw strings, improving error handling, and simplifying handler interfaces.
