Send control messages to DLT Daemon

## NAME

**dlt-control** - Send control messages to DLT Daemon

## SYNOPSIS

**dlt-control** \[**-v**\] \[**-h**\] \[**-S**\] \[**-R**\] \[**-y**\] \[**-b** baudrate\] \[**-e** ecuid\] \[**-a** id\] \[**-c** id\] \[**-s** id\] \[**-m** message\] \[**-x** message\] \[**-t** milliseconds\] \[**-l** level\] \[**-r** tracestatus\] \[**-d** loglevel\] \[**-f** tracestatus\] \[**-i** enable\] \[**-o**\] \[**-g**\] \[**-j**\] \[**-u**\] \[**-p** port\] hostname/serial\_device\_name

## DESCRIPTION

Send control messages to DLT Daemon. This is useful when there is no client (e.g. DLT Viewer) available. It supports several control messages including: - Setting log level/trace level - Setting default log level/default trace level - Enable timing packets - Store configuration - Reset to factory default - Get logging information

**Note** Use -u option instead of hostname/serial\_device\_name if Unix Socket is used. See example for detail.

### OPTIONS

- \-v

  Verbose mode

- \-h

  Usage

- \-S

  Send message with serial header (Default: Without serial header)

- \-R

  Enable resync serial header

- \-y

  Serial device mode

- \-b

  Serial device baudrate (Default: 115200)

- \-e

  Set ECU ID (Default: RECV)

- \-a

  Control message application id

- \-c

  Control message context id

- \-s

  Control message injection service id

- \-m

  Control message injection in ASCII

- \-x

  Control message injection in Hex e.g. \`ad 01 24 ef'

- \-t

  Timeout to terminate application (Default:1000)

\-l

-

  ```
  Set the log level (0=off - 6=verbose, default= -1)
  supported options:
    -l level -a apid -c ctid
    -l level -a abc* (set level for all ctxts of apps name starts with abc)
    -l level -a apid (set level for all ctxts of this app)
    -l level -c xyz* (set level for all ctxts whose name starts with xyz)
    -l level -c ctid (set level for the particular ctxt)
    -l level (set level for all the registered contexts)
  ```

- \-r

  Set the trace status (0=off - 1=on, default=255) supported options: -r tracestatus -a apid -c ctid -r tracestatus -a abc\* (set status for all ctxts of apps name starts with abc) -r tracestatus -a apid (set status for all ctxts of this app) -r tracestatus -c xyz\* (set status for all ctxts whose name starts with xyz) -r tracestatus -c ctid (set status for the particular ctxt) -r tracestatus (set status for all the registered contexts)

- \-d

  Set the default log level (0=off - 5=verbose)

- \-f

  Set the default trace status (0=off - 1=on)

- \-i

  Enable timing packets (0=off - 1=on)

- \-o

  Store configuration

- \-g

  Reset to factory default

- \-j

  Get log info

- \-u

  unix port

- \-p

  Port for TCP communication (Default: 3490).

## EXAMPLES

Change log level of application “APP1” to DEBUG with unix port **dlt-control -a APP1 -l 5 -u**

Change log level of application “APP1” and context “CON1” to ERROR **dlt-control -a APP1 -c CON1 -l 2** **localhost**

Get logging information of current running applications with unix port (IPC: Unix Socket) **dlt-control -j -u**

Get logging information of current running applications (IPC:FIFO) **dlt-control -j localhost**

## EXIT STATUS

Non zero is returned in case of failure.
