Building an IR Blaster

[steets250]

Unfortunately, I don't know Luup, the only change that I made to the .lua file was to change a file name.

The log gives me this when I send out an IR code:
08 06/05/14 22:04:32.359 JobHandler_LuaUPnP::HandleActionRequest argument ProntoCode=0000 0068 0000 000D 0060 0018 0018 0018 0030 0018 0030 0018 0030 0018 0018 0018 0030 0018 0018 0018 0030 0018 0018 0018 0018 0018 0018 0018 0018 03EC <0x2d18b680>

I want to see 0x2d18b680 come up on the serial, but I get nothing. I did also test to make sure that the Arduino was sending out serial messages.

If any one want to give it a try, replace the existing file with the one below (one one small change, nothing else is affected), and then use the code I posted previously. After the IR device is added to Vera, go to Devices, Add Device, IR Device, Ok, Select the IR Transmitter, and Choose Guided Setup. Then pick a random brand and try a code.

L_Arduino.lua

I will sign off for now. Let me know if you get anything!

maybe tomorrow I can mess with it

thanks

I think you have to create your own implementation of SendProntoCode.

You must take care of and handle all actions in D_IrTransmitter1.xml. Edit the I_Arduino.xml where you will find the actions defined.

<action>
    <serviceId>urn:micasaverde-com:serviceId:IrTransmitter1</serviceId>
   	<name>SendProntoCode</name>
   	<run>if (p ~= nil) then p.sendProntoCode(lul_device, lul_settings.ProntoCode) end</run>
 </action> 

And then implement sendProntoCode in L_Arduino.lua which sends the actual code using sendCommand to gateway for further processing.

function sendProntoCode(device, prontoCode)
    sendCommand(luup.devices[device].id,"IR_SEND",prontoCode)
end

But as I said in an earlier post the normal ProntoCode is too large to fit in one message over the air. So either you have to send short codes or split them somehow.
ProntoCode=0000 0068 0000 000D 0060 0018 0018 0018 0030 0018 0030 0018 0030 0018 0018 0018 0030 0018 0018 0018 0030 0018 0018 0018 0018 0018 0018 0018 0018 03EC

Yes, but I think creating a state machine on the Arduino and storing these long pronto chains in flash may work.

If we can get it to send a single CHAR, that will allow is almost the entire ASCII set (minus the not useable) nearly 250 commands.

[steets250]

Hek - Thanks for the advice with the sendProntoCode! I will work on it today.

Bulldoglowell and Hek - I was just testing to see if the code would go through. I plan to have the Vera send out a number that represents a larger code stored in the Arduino.

[steets250]

I changed the files, and am now testing it out. Log says:

Last line looks promising. I guess I will try a shorter code, and see what I get.

[steets250]

Still nothing... I changed the some of the TV's IR codes (channel number buttons 1-6) to single digit numbers so that it would not be too big for serial. I case anyone wants to give it a shot, I attached the modified files.

I_Codeset_2.xml
D_Codeset_2.xml
I_Arduino1.xml
L_Arduino.lua
S_IR_Serial.ino

[hek]

Not sure if it matters but shouldn't deviceType be "urn:schemas-micasaverde-com:device:IrDevice:1" ?

IR = 		  {20, "urn:schemas-micasaverde-com:device:IrDevice:1", "D_IrTransmitter1.xml", "IR "}, 

And what is the difference between "D_IrDevice1.xml" and "D_IrTransmitter1.xml"? (source: http://wiki.micasaverde.com/index.php/Luup_UPNP_Files)

[steets250]

I believe that Ir device is the tV or DVD that is created , and transmittersend out the ir codes.

[steets250]

Might this be the problem?

The IR transmitter has no implementation file.

How do I get MySensors to create a device with I_IrTransmitter1.xml?

[hek]

If you create a IR device as a "child" to Arduino you must handle all implementation yourself (like we just did for sendprotocode in the Arduino plugin).

I would suggest you create a thread or PM guessed on the micsa-forum who has good experience with the IR-device and is a really nice chap.

@steets250 Hi there
I did not notice this interesting topic til today.

This might help:

http://blog.univers-domotique.com/2013/10/plugin-vera-arduir/

Give it a google translate ;-)

Thanks for the suggestion, however, the project talked about is going the wrong way. I want signals from Vera to the transmitter, not transmitter to Vera.

I got an IR receiver and programmed my codes into an Arduino program. For anyone wondering, I had no storage issues (previously talked about).I haven't given up on this yet (saving $200 is a pretty good motivation)! Still trying to find out how to get Vera to send a message to Vera with Vera's IR remote UI. Seeing as how I have been trying with absolutely no luck for the past few days, I might have to make me own remote UI.

I haven't contacted guessed yet but I will soon, still playing around with it myself.

Has anyone tried this yet?? Instructions above.

[Dvbit]

Ok. Please note that the guy in the post above talks about bidirectional signal "easily doable" in his post.
You may want to ask him ;-)
Tx for your wrk

[steets250]

@Dvbit I didn't see anything talking about a bidirectional signal. Where did you see that? I am going to check out what it says as well as the plugin files to see what I can find.

FWI: The IR receiver I ordered from RadioShack came, so I am able to program in the codes. It was mentioned earlier that the codes would take up a lot of space on the Arduino, but using the IRRemote library, receiving a remote signal gives me a hex that will work with some of my devices, so I don't see a storage issue. I have to remotes set up so far.

[BulldogLowell]

@steets250

If you need space, you could always attach external memory (SD card perhaps) .

Compressing the codes would be nice.

Cannot wait until you have this worked out!

[steets250]

So I got the Arduino side of it done! Did I make any mistakes?

MySensors_IR.ino

the codes all do what they need to?

interesting that the length of the codes vary so much

TV 1 = B10000

TV 0 = B101110011101001

[steets250]

I was quite surprised when I saw that. All of the codes work properly when used with the send sony command. On my second remote, it uses the NEC protocol, and has a longer code. Another remote I tested was coming in as only raw code, so if someone tried to use remotes with only raw code it could be pretty space consuming.

The sd card was a good idea! The program could also possible use multiple ir LEDs in different locations to get the signal to multiple devices, which is when the sd card might be needed.

I'm now checking over what changes hek suggested earlier, and comparing it with some other mysensors devices. It seems like the vera is not sending a message through the send pronto code function that is described below.

Trying to change the code that Vera transmits, I discover this: :angry::angry::angry::angry::angry:

Right after selecting it here:

I'm not sure why Vera refuses to accept the Arduino as an IR transmitter. I will give the SQ blaster plugin another look at to see what they have.
