Open a Kvaser CAN bus log file in the current session.

Args: file_path: Path to the Kvaser CAN log file session_id: Optional session identifier (auto-generated if not provided)

Returns: File information and session details

Execute SQL queries against CAN bus log data using lnav's SQL engine.

Args: query: SQLite query to execute (use table name 'frames') limit: Maximum rows to return (default: 100) session_id: Session identifier

Returns: Query results with columns and rows

Extract specific CAN frames by ID, channel, or time range.

Args: can_id: CAN ID to filter (hex format, e.g., '0x123') channel: CAN channel number (0-based) start_time: Start timestamp end_time: End timestamp limit: Maximum frames to return (default: 1000) session_id: Session identifier

Returns: List of CAN frames

Generate statistical analysis of CAN bus traffic.

Args: stat_type: Type of statistics ("frequency", "timing", "load", "errors", "summary") interval: Time interval for aggregation (e.g., '1s', '100ms') can_id: Optional CAN ID to filter statistics session_id: Session identifier

Returns: Statistical data

Find error frames and anomalies in CAN bus logs.

Args: error_type: Type of error ("all", "crc", "bit", "stuff", "form", "ack", "timeout", "gap") channel: Optional channel filter session_id: Session identifier

Returns: List of error frames

Analyze CAN bus payload repetition to detect noise in logs.

Uses MD5 hashes of payload data to identify repeated payloads that may represent noise or meaningless data in the log.

Args: min_repetitions: Minimum number of repetitions to consider as noise (default: 10) session_id: Session identifier

Returns: Analysis of payload repetition and potential noise patterns

Scan CAN bus payload bytes for a specific decimal value.

Searches for frames where consecutive bytes in the payload match the binary representation of the given decimal value. Supports both big-endian and little-endian byte orders.

Args: byte_value: Decimal value to search for (0 to unlimited, auto-calculates byte width) endianness: Byte order ("big" or "little"), default: "big" start_offset: Start searching from this byte offset (default: 0) end_offset: Stop searching at this byte offset (default: None, searches to end) limit: Maximum frames to return (default: 1000) session_id: Session identifier

Returns: Matching frames with match position and context

Retrieve information about the current session state.

Args: session_id: Session identifier (uses most recent if not provided)

Returns: Session state information

Close the current session and release resources.

Args: session_id: Session identifier (uses most recent if not provided)

Returns: Confirmation message
