invalid suffix "F7403" on integer constant IR Library

I want to turn my xbox on/off with my arduino si i thought why not do it with ir? I have an old xbox 360 remote, not a controller, which has a on/off button on it. So, I used the ir library to dump the code and see what it was. It was a RC6 code, 800F7403, so i made a program to send this to the xbox. When i compiled the program i get this error "invalid suffix "F7403" on integer constant IR Library". What does it mean? i also tried dumping the raw values and sending them over, they did not gave any problems but the xbox just did not responded..

I would be thankful for some help.

It means you've got an invalid suffix somewhere in the code you didn't post.
Don't forget the code tags

800F7403,3

That one. It needs a 0x on the front, and a UL suffix wouldn't hurt

oh, right... Thanks haha :slight_smile:
