this code was worked. but there is some problem that i can not found ! some code sent and some dont send. also some time for many time can not work just with reset or power off/on. @hek please tag some members and programmer here that they can repair this code. this code is very efficient...
then you can use this sketch in site for RF 315 and 433 mhz device...
this code can solve some problem about short range of NRF. we can define many child id that every child can control many device with RF315 or RF433. for example for more distance we can use this node. with 315mhz and long distance...
