#send_tester_present(bus, src_id, dst_id, opt = {}) ⇒ Hash

Sends a TestPresent message. This message maintains previously set DSCs or Security Access levels so they don’t timeout and revert back to normal. TesterPresent is typically transmitted on 2-3 second intervals

Parameters:

  • bus (String) —

    unique CAN bus identifier

  • src_id (Integer) —

    Integer representation of the Sending CAN ID

  • dst_id (Integer) —

    Integer representation of the receiving CAN ID

  • opt (Hash) (defaults to: {}) —

    Optional arguments such as: PADDING if set uses this hex value for padding SUPPRESS_RESPONSE By default suppress ACK from ECU. Set to false if you want confirmation

Returns:

  • (Hash) —

    Packet hash from client.automotive. Typically blank unless suppress_response is false

    Integer representation of the Sending CAN ID

  • dst_id (Integer) —

    Integer representation of the receiving CAN ID

  • level (Integer) —

    The desired DSC level

  • opt (Hash) (defaults to: {}) —

#write_data_by_id(bus, src_id, dst_id, id, data, opt = {}) ⇒ Hash

Writes data by ID

Parameters:

    unique CAN bus identifier

  • src_id (Integer) —

    Integer representation of the Sending CAN ID

  • dst_id (Integer) —

    Integer representation of the receiving CAN ID

    Array of bytes to write

  • opt (Hash) (defaults to: {}) —

    Optional settings. PADDING if set uses this hex value for padding

Returns:

  • (Hash) —

    Packet hash from client.automotive
