Iíve always had issues with RS232 inputs in HEX. Iím hoping someone can help. I created two simplified examples to help explain the issue.
In Scenario 1, I just send a HEX code to the TV. Works perfectly.
In Scenario 2, I manipulated data and create the HEX code in the necessary format. When I send to the TV, it does nothing.
Does anyone know what I need to do in Scenario 2 to get the TV to accept the code? It is likely some type of ASCII to HEX conversion but canít figure it out.
var SendHex1 = "\x08\x22\x01\x00\x00\x0F\xC6";
System.print("SendHex1 [" + SendHex1 + "]");
SendHex1 [ " [hex format]
TV resets volume to 15
var SendHex2 = "08 22 01 00 00 0F C6";
SendHex2 = "\\x" + SendHex2.replace(/\s/g, "\\x");
System.print("SendHex2 [" + SendHex2 + "]");
TV does nothing

Well, the outputs don't look the same. Not sure if that's a mistype on your end.
Also, depending on the compiler, if you've specified 0x before an alphanumeric, it may treat it as byte code and thus not a string, the minute you start manipulating a string, it will always treat it as a string. Thus the ASCII to hex conversion issue.
Maybe try converting to binary afterwards and see what the 1s and 0s are.
Never underestimate the predictability of stupidity
