I've got 2 Arduino's running. One transmits 4 numbers every minute via a 433MHZ wireless module at 1200 baud (Using VirtualWire)
The other receives these numbers and sends them to the PC via a serial port. The numbers transmitted to computer are in the format "*,no1, no2, no3, no4,#"
Everything is so far working great - the problem I've found is that the receiver randomly stops working (most of the time after an hour)
If I reset the receiver it starts working again.
I've posted my code below, does anything stand out which could cause a problem. Hopefully I'm missing something simple as I can't understand why the code stops. It seems pretty simple enough.
#define rxPin 4
#define txPin 5
vw_setup(1200); // Bits per sec
vw_rx_start(); // Start the receiver PLL running
uint8_t buflen = VW_MAX_MESSAGE_LEN;
if (vw_get_message(buf, &buflen)) // check to see if anything has been received
Serial.print("*"); //Start Bit
for (int i = 0; i < 4; i++)
numbers[i] = word(buf[i*2+1], buf[i*2]);
Serial.print("#"); //Stop Bit
