how to send coded binary value value and decode via RF 433 Mhz

Using Arduino Programming Questions

I try to have a 5 digital channels remote with 2 arduinos and RF 433MHz (Tx/Rx) Modules

I decided to code the button's states with a binary number (each bit is a button's state). An easy way to add some buttons if I need it.

This sketch code and send via serial the binary value, but I need to send it via RF communication, and I'm stuck here.
I think this code to send via RF is ok
char msg[7] = {BStates, BIN};
vw_send((uint8_t *)msg, 7);
vw_wait_tx(); // Wait until the whole message is gone
delay(1000);

But I can't find how to to receive it and decode to have 5 digital outputs...

There is the Tx code

// declare names and pins
int Button1 = 4;
int Button2 = 5;
int Button3 = 6;
int Button4 = 7;
int Button5 = 8;  


void setup() {
 // initialize serial at 9600 bps
 Serial.begin(9600);
 
 // input mode for inputs
 pinMode(Button1, INPUT);
 pinMode(Button2, INPUT);
 pinMode(Button3, INPUT);
 pinMode(Button4, INPUT);
 pinMode(Button5, INPUT);
}


void loop() {
// code each state for binary word (DEC to BIN)
byte B1state = (digitalRead(4));      // 1st bit
byte B2state = (2 * digitalRead(5));  //2nd bit
byte B3state = (4 * digitalRead(6));  // 3rd bit
byte B4state = (8 * digitalRead(7));  // 4th bit
byte B5state = (16 * digitalRead(8)); // 5th bit
byte BStates = (B1state + B2state + B3state + B4state + B5state); // create 5 bits word
 Serial.println(BStates, BIN);   //send the 5 bits word
 delay(10);        // delay between loops

 char msg[7] = {BStates, BIN};
 vw_send((uint8_t *)msg, 7);
 vw_wait_tx(); // Wait until the whole message is gone
 delay(1000);
}

I tried some sketch to receive this code but nothing works...

Thanks for your help..

 char msg[7] = {BStates, BIN};

You're initializing the first byte of msg[] with Bstates, and the second with the defined constant BIN. A char array doesn't act like a serial print. Please look it up in the IDE reference.

msg[0] = BStates;
 vw_send((uint8_t *)msg, 1);

might work.
but you have to declare msg separately, before you assign data to it (for example, by declaring it outside of loop() or setup():

 uint8_t msg[1];
