Transmit date de HX711 by 433 Mhz RF transmissor

Hi, everyone, I have tried to send the weight data obtained from HX711 by 433MHz RF transmissor. Unfortunately, It does not work. I have tried to put the serial print in the parte de transmission and it shows everything well. However, the parte de receptor can not print the correct result. If anyone can help I will be very appreciated. Here is the code for transmission and reception
Transmission:

#include <HX711_ADC.h> // GitHub - olkal/HX711_ADC: Arduino library for the HX711 24-bit ADC for weight scales
#include <Wire.h>
#include <TM1637.h>
#include <RH_ASK.h> // Include RadioHead Amplitude Shift Keying Library
#include <SPI.h> // Not actually used but needed to compile

String str_out;// Define output strings

RH_ASK driver;// Create Amplitude Shift Keying Object
unsigned long event = 25000;// 25 seconds
unsigned long previousMillis = 0; //inicial value
const long period = 2000; // 2s period
HX711_ADC LoadCell(4, 5); // Pin de load cell.
TM1637 tm(2, 3);//Pin 2 - > CLK Pin 3 - > DIO

void setup() {
Serial.begin(9600); // Setup Serial Monitor
pinMode(6, OUTPUT);
driver.init();// Initialize ASK Object
tm.begin();
tm.setBrightness(4);
LoadCell.begin(); // start connection to HX711
LoadCell.start(2000); // load cells gets 2000ms of time to stabilize
LoadCell.setCalFactor(23.13); // calibration factor for load cell => strongly dependent on your individual setup

}

void loop() {
if(millis() <= event)
{
LoadCell.update(); // retrieves data from the load cell
float i = LoadCell.getData(); // get output value
tm.display(i/1000);// print out the retrieved value to the second row in kg

unsigned long currentMillis = millis(); // store the current time
if (currentMillis - previousMillis >= period) { // check if 2000ms passed
previousMillis = currentMillis; // save the last time
str_out = String(i/1000);// Convert Weight to string
static char *msg = str_out.c_str();

driver.send((uint8_t *)msg, strlen(msg));
driver.waitPacketSent();
Serial.print("Weight: ");
Serial.println(str_out);}

}
else {

digitalWrite(6, HIGH);}
}

Recption:
//Demonstrates 433 MHz RF Receiver Module with DHT11 Sensor

#include <RH_ASK.h>// Include dependant SPI Library
#include <SPI.h> // Not actually used but needed to compile

String str_out;// Define output strings

RH_ASK driver;// Create Amplitude Shift Keying Object
// RH_ASK driver(2000, 4, 5, 0); // ESP8266 or ESP32: do not use pin 11 or 2

void setup()
{
Serial.begin(9600); // Setup Serial Monitor
driver.init();// Initialize ASK Object
}

void loop()
{
uint8_t buf[5];// Set buffer to size of expected message
// uint8_t buf[RH_ASK_MAX_MESSAGE_LEN];// Set buffer to size of expected message
uint8_t buflen = sizeof(buf); // Check if received packet is correct size

if (driver.recv(buf, &buflen)) // Non-blocking
{

// int i;

// Message with a good checksum received, dump it.

// driver.printBuffer("Got:", buf, buflen);
// Convert received data into string
str_out = String((char*)buf);

  // Print values to Serial Monitor
  Serial.print("Weight: ");
  Serial.println(str_out);
  
     
}

}

Did you get the radios to work using the RH library examples before writing this code?

Does the receiver get anything? If so what?

A schematic of the project and photos of the wiring will be helpful.

Read the forum guidelines to see how to get the best from the forum.

Thank you for your response.
Yes, it is works well with DHT11 temperature and humidity sensor, and also AHT10 sensor.
The differnece is with this Hx711 sensor, the delay cannot be used, otherwise, I could not get the correct results. So I have to use the millis.
The wiring is correct as I can get the data in LED display. I just want to send the data by rf 433MHz for other arduino and show it in other device. By RadioHead-Master liberary, the defaut conection is D12 for transmission and D11 for reception. I did not change them as they workd well with the onter sensors.
