arduino 433mhz software setup

I have 433 mhz arduino software partially working. I can send "this is a string" but cant send number for (int i=0; i <= 4000; i++){ ...send this is string number i } i would also like the 433 mhz units to have two way coms between multiple units. ie temperature of three separate arduino units broadcast to each of them // [login to view URL] transmitter with an TX-C1 module // See VirtualWire.h for detailed API docs #include #undef int #undef abs #undef double #undef float #undef round void setup() { [login to view URL]("setup"); // Initialise the IO and ISR vw_set_ptt_inverted(true); // Required for DR3100 vw_setup(2000); // Bits per sec int loops = 0; } void loop() { int loops; int loops2; loops=loops2+1; loops2=loops; //String stringOne = "Hello String"; for (int i=0; i <= 4000; i++){ String testone="test"; String testtwo=String(testone) +String(i,DEC); [login to view URL](testtwo); const char *msg = "hello Bj"; //char *msg = "hello Bj" + String(i,DEC); char msg = "hello Bj" + i; [login to view URL]("start"); delay(500); digitalWrite(13, true); // Flash a light to show transmitting vw_send((uint8_t *)msg, strlen(msg)); // vw_send((uint8_t *)testtwo, strlen(testtwo)); vw_wait_tx(); // Wait until the whole message is gone } } this is the hardware connected to pins 11(xmit) & 12 (rcv) [login to view URL]:L:OC:AU:3160 no hardware needs to be built or supplied on this project.
