Save bytes in float variable

Projects Programming

I tried the memcpy(); but somehow is not working well.
I changed my code a little bit, so now i´m not saving the data values directly in the float variable, but in a byte Array.

const size_t floatSize = sizeof(float);
 uint8_t bytes[floatSize];

void loop()
{
  can_message_t rx_frame;
  if(can_receive(&rx_frame,pdMS_TO_TICKS(1000))==ESP_OK)
  {
    printf("from 0x%08X,DLC%d,data", rx_frame.identifier,rx_frame.data_length_code);
    for(int i=0;i<rx_frame.data_length_code;i++)
    {
      printf(" 0x%02X",rx_frame.data[i]);
      
    }
    printf(" Bytes values: ");
    
    for (int i=3; i>-1;i--)
    {
      bytes[i]=rx_frame.data[3-i];
    }
    printf(" 0x%02X 0x%02X 0x%02X 0x%02X  ",bytes[0],bytes[1],bytes[2],bytes[3]);
    //Lat_delta_distance= (rx_frame.data[3] << 24) + (rx_frame.data[2] << 16) + (rx_frame.data[1] << 8) + (rx_frame.data[0]); 
    memcpy(&Lat_delta_distance,bytes,floatSize);
    printf("; lat_dist: 0x%08X ; ", Lat_delta_distance);
    Serial.println(""); // linefeed

    printf("\n ");
  }
}

Output:

from 0x00000130,DLC8,data 0x00 0x00 0x0C 0x42 0x00 0x00 0x00 0x00
 Bytes values:  0x42 0x0C 0x00 0x00 //here is the 35 saved on the Bytes array
  ; lat_dist: 0x37588400 ; // After memcpy is the value completly different
                           // not the same as in Bytes values:
