I have Arduino Uno, Arduino Pro Micro, XY-MK-5V and FS1000A. I need transmit data from Pro Micro to Uno.

Transmitter:

    #include <VirtualWire.h>
    
    void setup() {
    
      Serial.begin(9600);
    
      vw_setup(2000);
      vw_set_tx_pin(14);
    }
    
    void loop() {
    
      send("Test message!");  
      delay(2000);
    }
    
    void send (char *message)
    {
      vw_send((uint8_t *)message, strlen(message));
      vw_wait_tx();
    }

Receiver:

#include <VirtualWire.h>

void setup()
{
    Serial.begin(9600);

    vw_set_rx_pin(12);
    vw_setup(2000);

    vw_rx_start();
}

void loop()
{
    uint8_t buf[VW_MAX_MESSAGE_LEN];
    uint8_t buflen = VW_MAX_MESSAGE_LEN;

    if(vw_get_message(buf, &buflen))
    {
        for(int i = 0; i < buflen; i++)
        {
            Serial.print(buf[i]);
        }

        Serial.println();
    }
}

I dont know why it's doesn't works. When I changed Uno with Micro and Micro with Uno, it's worked.

But I need: Micro + transmitter FS1000A & Uno + receiver XY-MK-5V.

Please help me.
