I'm using the 3715 RF arduino modules and a hc-sr04, and i'm trying to send the distance i get from the ultrasonic over to the arduino with the rf recieving module but i get something like this: 
Instead of getting this:
Here are the code snippets for each arduino:
Arduino TX:
#include <VirtualWire.h>
const int led_pin = 11;
const int transmit_pin = 12;
const int receive_pin = 2;
const int transmit_en_pin = 3;
long distance;
long time1;
void setup()
{
// Initialise the IO and ISR
Serial.begin(9600);
pinMode(9, OUTPUT);
pinMode(8, INPUT);
vw_set_tx_pin(transmit_pin);
vw_set_rx_pin(receive_pin);
vw_set_ptt_pin(transmit_en_pin);
vw_set_ptt_inverted(true); // Required for DR3100
vw_setup(2000); // Bits per sec
}
byte count = 1;
void loop()
{
digitalWrite(9,LOW);
delayMicroseconds(5);
digitalWrite(9, HIGH);
delayMicroseconds(10);
time1=pulseIn(8, HIGH);
distance= int(0.017*time1);
Serial.println("Distance ");
Serial.println(distance);
Serial.println(" cm");
delay(1000);
char msg[1] = {distance};
msg[0] = count;
digitalWrite(led_pin, HIGH); // Flash a light to show transmitting
vw_send((uint8_t *)msg, 3);
vw_wait_tx(); // Wait until the whole message is gone
digitalWrite(led_pin, LOW);
delay(1000);
}
Arduino RX:
#include <VirtualWire.h>
const int led_pin = 6;
const int transmit_pin = 12;
const int receive_pin = 11;
const int transmit_en_pin = 3;
void setup()
{
delay(1000);
Serial.begin(9600); // Debugging only
Serial.println("setup");
// Initialise the IO and ISR
vw_set_tx_pin(transmit_pin);
vw_set_rx_pin(receive_pin);
vw_set_ptt_pin(transmit_en_pin);
vw_set_ptt_inverted(true); // Required for DR3100
vw_setup(2000); // Bits per sec
vw_rx_start(); // Start the receiver PLL running
}
void loop()
{
uint8_t buf[VW_MAX_MESSAGE_LEN];
uint8_t buflen = VW_MAX_MESSAGE_LEN;
if (vw_get_message(buf, &buflen)) // Non-blocking
{
int i;
digitalWrite(led_pin, HIGH); // Flash a light to show received good message
// Message with a good checksum received, print it.
Serial.print("Got: ");
for (i = 0; i < buflen; i++)
{
Serial.print(buf[i], HEX);
Serial.print(' ');
}
Serial.println();
digitalWrite(led_pin, LOW);
}
}
I'm open for pointers as i'm pretty much a noob at this, thank you very much for your help! :)
