Samsung Galaxy 2 7.0 Tablet...

[Gary Miyakawa]

The documentation talks about the "IR Blaster" that is built in. I'd REALLY like to program it to do some magic but in searching here, I don't find that anyone has tried/used the IR Blaster.

Does anyone have any experience programming it ? Or suggestions ?

Thanks,

Gary M

I did find this sample code but not sure how to impliment it in B4A.. Could someone help with this ? BTW, this code came from XDA forums.

public void onClick2(View view) {
       TextView editText = (TextView) findViewById(R.id.textView2);
       
       Object irService = getSystemService("irda");
       irService.getClass();
       Class irClass = irService.getClass();
       Class params[] = new Class[1];
       params[0] = String.class;
       try {
         Method sendIR = irClass.getMethod("write_irsend", params);
         
         for(int i=0;i<2;i++)
            sendIR.invoke(irService, "37300,11,67,10,28,10,28,10,27,11,27,11,27,11,67,11,67,11,27,11,68,10,27,11,27,11,27,11,67,11,27,11,1731,11,68,10,28,10,27,11,27,11,27,11,67,11,27,11,27,11,67,11,27,11,67,11,67,11,68,10,27,11,68,10,1653");
         editText.setText("Done");
      } catch (Exception e) {
         e.printStackTrace();
         editText.setText("Fail");
      }
    }

Thanks,

looks like you could possibly do it with the reflection library too

Thank you for the lead! I just picked up a 10.1 to start testing with. Any suggestions I would greatly appreciate !

I'm not a Java person and this reflector (and coverting the code to run from reflector just isn't coming together for me at this time...)

vb1992 kindly pointed me to a smaller piece of code that "should" send something to the embedded IR on my Galaxy Tab but I haven't been able to get thru the syntax...

The code that vb1992 found is as follows:

'   Try{ 
'      Object irService = getSystemService("irda"); 
'      irService.getClass(); 
'      Class irClass = irService.getClass(); 
'      Class params[] = new Class[1]; 
'      params[0] = String.class; 
'      Method sendIR = irClass.getMethod("write_irsend", params); 
'      SendIR.invoke(irService,"data"); 
'    } Catch (Exception e){ 
'      //Do something with the error 
'    }

Could someone, with MUCH more knowldege about reflector than I (i'm a zero) help me undestand how to convert it run (hopefully) on B4A ?

Thanks much !

Try this:

Dim r As Reflector
r.Target = r.GetContext
r.Target = r.RunMethod2("getSystemService", "irda", "java.lang.String")
r.RunMethod2("write_irsend", "data", "java.lang.String")

Thank you! I'll give it a try !

Curious if you ever got this working

I know this is a bit of an old thread but I am curious if anyone has gotten this working yet as well. I would like to be able to learn (store) IR data as well as transmit it.

I'd like to know as well!
