DeviLAN App / CONFIGURABLE REMOTE CONTROL
Search & Configure Remote Control Download
 Remote control (getting started)

Use your iPhone, iPad or iPod as a TCP/IP based Remote Control and visualization tool !!

No time to write an own App to control your network device via socket ?
Not familiar with iOS programming ?
No problem!

Just use our DeviLAN App to create your own remote control or send accelerometer, geo, teslameter and compass data to control your device. A 'Device' can be an embedded system, a PC, a laptop or any other network based modul. You only have to be able to write own network based applications for your device.

As example we offer a free sample project for Linux.

Remote control function is available with Version 1.3 of DeviLAN App.
(Get here newest Version 1.8 (available soon) from Apple Appstore.)

... and now getting started ....

New in version 1.8: Portrait and Landscape mode supported for iPhone & iPad

 Prepare commnunication between devices
To prepare communication between your device and some iOS device:

  • Open a TCP/IP listen socket on a free port at your device.
  • Start DeviLAN App an open tab "Socket".
  • Enter your device IP and port number and press 'Connect' button to get a connection.
  • When connection is open send command "modul_typ remote" to DeviLAN App.
  • The App will now add two subviews called
    "Accelerometer", "Geo Data & Magnetics/Compass" and
    "Remote Control"
  • Tab on entry "Remote Control"...
  • .... and you see an empty view?? (that's fine but useless ;-))
  • Additionally DeviLAN App sends a "get_config" command to ask for the configuration of your remote control. It also sends "modul_version DeviLAN App 1.7 Build 8" to give the server the information about app's software version.
  • Now your device has to send the configuration for remote control.
  • .... and that's it! Your device can be remote controlled by your iOS device!

 Remote control & visualization elements
At the moment there a the following simple control & visualization elements
(but we will add more in the future versions)
DeviLAN App remote control
 Socket protocol
The communication with DeviLAN App is ASCII command line based where every command start with a keyword (command) followed by a parameter or a parameter list:

'command' 'SP' ['Para1'][;'Para2'].....[;'Para n'] 'CR'

  • Every command line ends with a 'CR' = "Carriage Return".
  • 'SP' = "Space" means exactly ONE space character.
  • Parameters in a list are separated by ;. (semicolon)
  • All commands for remote control starts with rmt_ (abbr. for remote)
  • Some commands have no parameter

... and here are the elements ....

 Draw element: drawing behavior
All objects in a draw element are stored in a list because of redrawing reasons. When draw element receives a command to add an object it puts it into the list first. Drawing itself is controlled by the update mode.
So there are the follwing commands to change the drawing behavior:

To change drawing mode to 'n'o update directly send command:

'rmt_draw1_XX_data' 'SP' ';'n' 'CR'

In this case all object received will only added to the list without drawing.

To change drawing mode to 'u'pdate directly send command:

'rmt_draw1_XX_data' 'SP' ';'u' 'CR'

In this case all object received will added to the list and all objects are drawn again.


The when you don't want that the objects are drawn piece by piece when the draw element receives it
  • first send 'n' command to avoid drawing directly
  • then send all elements for the graphic
  • and after that send 'u' command to draw all objects

To 'd'elete the list send command:

'rmt_draw1_XX_data' 'SP' ';'d' 'CR'

Alle elements will be removed from list and the draw area is filled with the draw color.

Examples (delete, no update, update):

rmt_draw1_XX_data ;d
rmt_draw1_XX_data ;n
rmt_draw1_XX_data ;u

 Special command & more infos
There are some special commands:

To remove all elements send:

'rmt_clear 'SP' 'CR'

Removing elements can be helpfull to send a new remote view. You don't have to add all elements you need in remote controller view.
e.g.: Send remote control with a lot of buttons. When a special button is pressed your device can send the remove command and thereafter a new RC configuration.

When connection was established to device or the orientation changes RC sends:

'rmt_hardware' 'SP' 'platform' 'width' 'height' 'CR'

where
  • 'platform' is the hardware platform and generation of device (iPhone, iPad, etc.)
  • 'width' is the width (in pixel) of the RC screen
  • 'height' is the height (in pixel) of the RC screen
This commands let the RC server know on which device the app is running and how large the screen is. It can be used to create different GUI for iPhone and iPad and orientations (Portrait or Landscape).

Some more things to know:
  • When you send a command to remote controller that is kown (was used before) again the element will be updated not added. So you can change the text, range or state at any time (e.g. to give the user a feedback).

  • You can add new elements at any time.

  • The elements are shown in the order your device sends the configuration commands.

  • The max. no. of elements is 100. When you need more use the clear command and send new remote view(s).

  • When you what to send all values of all elements press button 'Send all'.

  • To remove all elements from remote control view press button 'Clear'

  • To reload all all elements press button "Reload". DeviLAN App will send get_config to your devices that now knows it has to send configuration again.

 Demo mode
We added a special demo mode to demonstrate how a remote control could work.
There are two ways to start it.


First:
  • At the Start tab press button 'Start RC demo'.
  • App will to go tab 'socket' and performs the start of the demo.




Second:
  • Go to Socket tab
  • Enter command 'modul_typ remote' in edit field
  • Press send button
  • Now the three subviews called
    "Accelerometer",
    Geo Data & Magnetis/Compass and
    "Remote Control" will be added.
  • Select "Remote Control"
  • You see an emtpy remote control, press button "Start Demo" to start the demo mode.
  • Now several elements will be added and updated automatically.
  • Press button ("Stop demo") again to stop demo.

 Testing commands

To test a command you can also directly edit it. Go to the "socket" tab and add '@' before the command and press "Send" button. Commands that starts with '@' are not transmitted to your device!! The '@' will be removed and the command will be processed like a command that has been received via socket.

E.g.: to test the clear command just edit:

@rmt_clear

and press "Send" button.

This mechanism works with all commands that command interpreter of DeviLAN App knows.

 PC tool DeviLAN Control

He added a remote control server to our PC tool called DeviLAN Control. This can be used as a RC server, so you can see how DeviLAN App remote control function could be used for your application.
Just do the following:

  • Install DeviLAN Control at your PC which you find here:
    DeviLANControl_112_Installer.exe
  • Start the program and select tab "Socket-PC"
    (don't worry about some parts of GUI are in german, you don't need them ;-))
  • The program automatically will open a "listening socket" at port 3333 at default.
  • Press button"Show" right fom text 'DeviLAN App RC Tester' at the bottom of tab.
  • Now a new tab occurs called "RC Test".

  • Start "DeviLAN App" and go to tab "Socket"
  • Enter your PC-IP e.g. "192.168.1.3" and port no. "3333" and press button "Connect" to establish a connection with PC tool
  • Now select entry Remote Control

  • Go back to PC tool and choose the RC control scene you want to see and follow the commands "Received & tranmitted commands".

We also offer free sample code for Linux that allows you to see how a RC server could work. It does the same as RC server part of PC tool DeviLAN Control.
You can download it here DeviLAN_App_RC_Server.zip .

 Accelerometer

To stream data from 3 axis accelerometer from your iOS device to your device just select the frequency for sending. You can get raw data directly from accelerometer or filter them before sending. Use the filter settings that are usefull for your application.

The data format for raw data sending is:

'rmt_accr_data 'SP' 'X' 'SP' 'Y' 'SP' 'Z' 'CR'

and

'rmt_accf_data 'SP' 'X' 'SP' 'Y' 'SP' 'Z' 'CR'


for filtered where
  • 'X' is raw / filtered value of accelerometer x
    (format: float, two digits after dot, '%5.2f')
  • 'Y' is raw / filtered value of accelerometer y
    (format: float, two digits after dot, '%5.2f') and
  • 'Z' is raw / filtered value of accelerometer z
    (format: float, two digits after dot, '%5.2f')
