Data Sizing Optimization for Server

What's picking it up on the server side?

Can you read binary on the server side per


struct MyData
{
  float X;
  float Y;
  float Z;
  int T;
} myData;

void setup(void){

  float X = -0.2157;
  float Y = 0.6015;
  float Z = 9.5582;
  int T = 143;

  myData.X = X; 
  myData.Y = Y; 
  myData.Z = Z;
  myData.T = T;

  Serial.print("binary::");
  Serial.write((byte*)&myData, sizeof(myData));
  Serial.println("::/binary");}

void loop(void){
}

...prints this on the serial monitor:

binary::và\¾çû?cîA::/binary

...which might be awkward to parse on the server.

Or since accelerometer data probably isn't accurate to the 100 micro-G range, consider a fixed format like: "-0215+0602+9558143"

char buff[50];

float X=-0.2157;
float Y=0.6015;
float Z=9.5582;
int T=143;

sprintf(buff,"%+05d%+05d%+05d%03d",(int)(X*1000+0.5),(int)(Y*1000+0.5),(int)(Z*1000+0.5),T);
Serial.begin(115200);
Serial.println(buff);
