Good night,
I have a problem and need to solve urgently.
The code should work, but is a problem in the library VirtualWire or IR Remote.
The first time the IR code is sent and the box changes channel, but as you enter the sub program receive when the IR code is sent again, no longer works.
If not using VirtualWire the code works fine, but the VirutalWire need to receive data from the rf.
I thank you
