Sending Hex codes over serial

Hi,

I'm trying to control a DVR with a GC WF2SL.

If I send the command FF 55 09 (Hex) using iTest my DVR responds as it should

But I can't figure out how to make Roomie do the same.

I've made several custom devices using the DDK. For this one I've set method to <em>binary </em>and as code I've entered <em>FF 55 09</em>.

Obviously I'm doing something wrong :slight_smile:<em> </em>

I already tried binary-ack and lineio and FF5509 (without spaces)

Who can give me some pointers?

Thanks!

Here's an example of binary notation from the DDK:

<key>VOLUME UP</key>

<string>\x02\x02\xA0\x55\x09</string>

To use raw binary without "\x", you'd need to use Xcode. So the simpler method is usually to use a string type and then just use the \x escape method.

Thank you.

Wow, that did the trick!

Thanks a lot :slight_smile:
