Need help - Just want to make a simple switch using RF Modules

Might be able to do what you want by counting. Keeping track of the last push...

But you will only have to count to one. The count VAR could start at 0. When the button is pushed...
IF COUNT VAR = 0 THEN
TX XYZ
COUNT VAR = 1
ELSE
IF COUNT VAR = 1 THEN
TX ZYX
COUNT VAR = 0

EEPROM may be required...

Something like that

Thanks for the answer, but I am sorry I couldn´t get your point how this will help. Could you explain a bit more please.
