Samsung Soundbar protocol raw questions

[jorgeci]

Hi,

I was trying decode a soundbar samsung code and I found something that i think is a little strange, Note: I'm using a esp8266 with the irlib.

Encoding : UNKNOWN
Code : CA31DA45 (32 bits)
Timing[77]:
+4550, -4450 + 550, - 500 + 550, - 500 + 550, - 500
+ 550, - 500 + 550, -1450 + 600, -1450 + 600, - 500
+ 550, - 500 + 550, -1450 + 550, -1450 + 600, -1500
+ 550, -1500 + 550, - 500 + 550, - 500 + 550, - 450
+ 600, - 500 + 550, -4450 + 550, - 500 + 550, - 500
+ 550, - 450 + 600, - 450 + 600, - 500 + 550, - 450
+ 600, - 450 + 550, - 550 + 550, -1450 + 600, -1500
+ 550, -1500 + 550, - 500 + 550, -1500 + 550, -1500
+ 550, -1500 + 500, -1500 + 550, - 500 + 550, - 500
+ 550, - 500 + 550, -1500 + 550
unsigned int rawData[77] = {4550,4450, 550,500, 550,500, 550,500, 550,500, 550,1450, 600,1450, 600,500, 550,500, 550,1450, 550,1450, 600,1500, 550,1500, 550,500, 550,500, 550,450, 600,500, 550,4450, 550,500, 550,500, 550,450, 600,450, 600,500, 550,450, 600,450, 550,550, 550,1450, 600,1500, 550,1500, 550,500, 550,1500, 550,1500, 550,1500, 500,1500, 550,500, 550,500, 550,500, 550,1500, 550}; // UNKNOWN CA31DA45


In the middle of the raw information I found the 4450, this is not a mark or a space, is another header maybe? is an error?, Any ideas what this means?
The code is the power button but I found a similar think with all the other buttons

Thanks

It is not uncommon for an additional header to appear in the middle of a signal like this.

If you are getting consistent readings like this then is likely OK.

It seems to be an initial 16 bits followed by another 20 bits in the second part.


The best test is to see if it works when you resend it.

What Ir receiverare you using...make sure to power it from 3V3 on the ESP (not 5v)
