Problem with transmitting IMU/GPS/Ultrasonic data over Nrf24L01

HI there.
I have a problem with trying to transmit data from sensors from my bot using a mega with a NRF24L01 (long range 1,000m ver) to my base station using an UNO with same NRF24.
I "think" it has to do with sending various types of data at once like ints floats strings?
Can some one with experience in sending GPS or other like sensor data kind of guide me in this?
The TX sends some sort of data but it's all mucked up on the RX I do not know if it's getting messed up before (when being stuffed into the array for transmission) or after ti's being sent.
Here is my (TX) Code

void NrfTrans(){
  //****************************Info being Sent**********************
   // GPS NMEA data (3 vals)
  // IMU Roll Pitch Yaw (3 vals)
  //**************put values in array?**************
  byte vals[6];
  //**********Send IMU Roll Pitch Yaw values**********
  vals[0] =ToDeg(roll);   //example   + or - 134.987 
  vals[1] =ToDeg(pitch); //example + or - 134.987 
  vals[2] =ToDeg(yaw); // example  + or - 134.987 
  vals[3] =flat;             //example 40.111111111 
  vals[4] =flon;          //example -40.111111111 
  vals[5] =Tgps.satellites(); //example 8
  //**************************************************
  //**************finish putting values in array?************** 
  //**************Start Transmit package**************
  Mirf.setTADDR((byte *)"base1"); // set name of Reciever
  Mirf.send(vals); // data to send
  Serial.println(" Sent");
  while(Mirf.isSending()){
  }
  delay(10);
}

Here is my base station code (RX)

You need to post ALL of your code for us to have any real chance of seeing the problem, but I suspect the problem may be that you're trying to store float values in bytes.

tried to post the full code but the forum spit it back saying it was over the max 9500 chars. here is the TX so ill have to split it in 2 or more posts

You don't have a clue about variable types, do you? You can't store floating point data in 8 bit, integer variables.

And, this is quite novel:

    return flat,flon;

Completely wrong, but you get points for inventiveness.

i use the ESC codes for VT100 term output, i took them out because i know most of you use the generic arduino ide serial monitor.
They now have been removed.
as for the return well i am still quite learning i just learned last week how to pass arguments to external functions so still need lots of work learning how to get them out.
i am still shopping in the noob section i think.
as for trying to stuff floats into byte array yea i know it would not work but it showed what i need to accomplish.
if i had a nickle for every float to byte, f to b array converter i have looked at in the past 4 days i would be able to buy a starbucks coffee.
i am thinking type casting is where i need to look? or i have seen some typedef union stuff.
so to answer your question NO i do not know much about var types and i am not that experienced with programing on any level.
but i keep plugging away at it and learning as i go.
so i will say sorry now for being bad at programming and if that is not welcome here let me know.
so any ideas on fixes for the return flat,flon and ANY help on the float to byte method would be fantastic.

Well if you want to pass a bunch of different data types, I suggest you define
a struct with your data and then a union to an array of bytes.

Find a C textbook and read the section about structs and unions.

And then read about how functions work.

And then read about data types.

WOW thanks i got your post a couple min after to made and and just got it to work. here is what i did

TX side

union imur_t {
   byte  Uroll[4];
   float froll;
 }imur;
   imur.froll = ToDeg(roll);
  byte vals[4];
  vals[0] = imur.Uroll[0];
  vals[1] = imur.Uroll[1];  
  vals[2] = imur.Uroll[2];
  vals[3] = imur.Uroll[3];

then i push vals out like before in the Nrf function
and i did the reverse on the other side like this

RX side

 union imur_t {
   byte  Uroll[4];
   float froll;
 }imur;
    imur.Uroll[0] = data[0];
    imur.Uroll[1] = data[1];
    imur.Uroll[2] = data[2];
    imur.Uroll[3] = data[3];

and then printed it out and boom there it was. -0.03 or 1.37 etc what ever the roll on the IMU was it sent it across. WOOT!. yes i am excited cos that %100 my own work. took over WELL over 100 tries the past few hours. it's now 1:33am here time for bedZ. now the big question is there better why than this because i have roll pitch yaw just on the imu and then i have the GPS sentences and the ultrasonic stuffs to do along with others. do i have to create... ( brain fart, cant i just make a function and send it transmit var in the type of a float and have it return the bytes and send them auto to the nrf?) like f2bconv(Sensor1()); and sen 1 being in form of a float be chopped and passed to Mirf.send? sorry it is real late here and i am not "good" at this fresh in the morning much less now lol. ill translate this in the morning! :slight_smile: ( i hope)

The function to send an array of bytes can send the bytes from any memory location. Define a struct. Store the data in an instance of the struct. Call the function to send the data with the struct instance and the size of the struct.

That function does not want a struct? Lie to it. Tell it that the struct is really a collection of bytes, using a cast - (byte *). Use the sizeof() function to get the number of bytes to send.

like this but with structs?
i did this last night before i went to bed.
TX

float Tflo2byte(float inflo){

  union flow2byte_t {
    byte  outbyte[4];
    float infloat;
  }
  flow2byte;
  flow2byte.infloat = inflo;
  byte output[4];
  output[0] = flow2byte.outbyte[0];
  output[1] = flow2byte.outbyte[1];  
  output[2] = flow2byte.outbyte[2];
  output[3] = flow2byte.outbyte[3]; 

  Mirf.setTADDR((byte *)"base1"); // set name of Reciever
  Mirf.send(output); // data to send
  while(Mirf.isSending()){
  }
  delay(10);
}

Rx side in main loop

byte data[Mirf.payload];
  if(Mirf.dataReady()){
    do{
      Mirf.getData(data);
      byte2flo(data); // send to byte to float converter
      delay(10);	
    }
    while(!Mirf.rxFifoEmpty());
  }

external to loop

void byte2flo(byte data[]){
  //*********** Start convertion from byte to float *********
  union byte2flo_t {
    byte  outbyte[4];
    float outfloat;
  }
  byte2flo;
  byte2flo.outbyte[0]= data[0];
  byte2flo.outbyte[1]= data[1];  
  byte2flo.outbyte[2]= data[2];
  byte2flo.outbyte[3]= data[3]; 
  Serial.println(byte2flo.outfloat);
  //*********** END convertion from byte to float ********* 
 
}

works but this is the output
0.38
-1.28
-12.58
now i have to "collect" the data and store it so i can turn that into something along the lines !IMU:0.38,-1.28,-12.58: (!) start of line (:slight_smile: end of line for external programs like processing or python.
point me in the general direction i need to do this? like some kind of scanning routine that watches the incoming data or something.
ill go check out structs now. thanks for the input PaulS and michinyon
i appreciate this a lot.

this does not compile i know. just wanted to know if i am heading in the right direction

   typedef struct{
    float roll;
    float pitch;
    float yaw;
  }floatImu;
  
   floatImu inImu[2];
  inImu[0].roll  = ToDeg(roll);
  inImu[0].pitch = ToDeg(pitch);
  inImu[0].yaw   = ToDeg(yaw);
  inImu[1] = (floatImu){roll,pitch,yaw};
  outD = inImu[1];
  
  Mirf.setTADDR((byte *)"base1"); // set name of Reciever
  Mirf.send(outD); // data to send
  while(Mirf.isSending()){
  }
  delay(10);

just wanted to know if i am heading in the right direction

You are not headed in the wrong direction.

It isn't clear why you have two instances of the struct, or what roll, pitch, and yaw are, or what outD is.

eep! 2? my understanding of stucts must be way off then here is what i understood it to be

RPYtransmit(ToDeg(roll),ToDeg(pitch),ToDeg(yaw));
void RPYtransmit(float inRoll, float inPitch, float inYaw){ //recieve current vals for ToDeg(roll),ToDeg(pitch),ToDeg(yaw)
 
    typedef struct 
    {
    float roll; // place for roll value here
    float pitch;// place for pitch value here
    float yaw;  // place for yaw value here
   }RPYT_type; // lable the struct

    RPYT_type imuArray[2]; // create an array to hold roll,pitch,yaw for transmission


  imuArray[0].roll  = inRoll; // give float roll in RPYT_type value from incoming function argument inRoll
  imuArray[0].pitch = inPitch;// give float pitch in RPYT_type value from incoming function argument inPitch
  imuArray[0].yaw   = inYaw;// give float yaw in RPYT_type value from incoming function argument inYaw
  imuArray[1] = (RPYT_type) {inRoll,inPitch,inYaw}; // combine inRoll,inPitch,inYaw from RPYT_type into imuArray position 2 (0 being first position in array) 

  Mirf.setTADDR((byte *)"base1"); // set name of Receiver
  Mirf.send(imuArray[2]); // figure out how to access and transmit second array segment containing inRoll,inPitch,inYaw
  while(Mirf.isSending()){
  }
  delay(10);
}
    RPYT_type imuArray[2]; // create an array to hold roll,pitch,yaw for transmission

This is creating an array of structs. The question is why? Why 2?

Each instance of the struct can hold roll, pitch, AND yaw. You do not heed three instances of the struct to hold the three values. And, you certainly don't need two instance for three values.

ahh ok think im starting to see now

void RPYtransmit(float inRoll, float inPitch, float inYaw){ //recieve current vals for ToDeg(roll),ToDeg(pitch),ToDeg(yaw)
 
    typedef struct 
    {
    float roll; // place roll value here
    float pitch;// place pitch value here
    float yaw;  // place yaw value here
   }RPYT_type; // lable the struct

  RPYT_type imuVal = {inRoll,inPitch,inYaw}; // give float roll in RPYT_type value from incoming function argumet inRoll
  Serial.println("");
    Serial.print(imuVal.roll);
  Serial.print(" , ");
    Serial.print(imuVal.pitch);
  Serial.print(" , ");
    Serial.print(imuVal.yaw);
  Serial.println("");
}

so how do i trick Mirf.send(); into thinking this is once piece of data?

Ok so far here is the transmit seems to be working

    typedef struct 
    {
    float roll; // place roll value here
    float pitch;// place pitch value here
    float yaw;  // place yaw value here
   }RPYT_type; // lable the struct

  RPYT_type imuVal = {inRoll,inPitch,inYaw}; // give float roll in RPYT_type value from incoming function argumet inRoll
  Serial.println("");
    Serial.print(imuVal.roll);
  Serial.print(" , ");
    Serial.print(imuVal.pitch);
  Serial.print(" , ");
    Serial.print(imuVal.yaw);
  Serial.println("");
  byte vals[3];
  vals[0] = imuVal.roll;
  vals[1] = imuVal.pitch;  
  vals[2] = imuVal.yaw;
  Mirf.setTADDR((byte *)"base1"); // set name of Reciever
  Mirf.send(vals); // figure out how to access and transmit second array segment containing inRoll,inPitch,inYaw

but on my rec side i have

void RPYT(byte data[3]){
  //*********** Start convertion from byte to float *********
  typedef struct{
    float roll;
    float pitch;
    float yaw;
   } RPYT_type;
  RPYT_type imuVal = {data[0],data[1],data[2]};
 
  Serial.print(imuVal.roll);
  Serial.print("'");
  Serial.print(imuVal.pitch);
  Serial.print("'");
  Serial.print(imuVal.yaw);
  Serial.println("");

my TX is sending this

-0.00 , -0.01 , 0.01
3.23 , -0.33 , 0.10
2.43 , 0.01 , 0.09

1.00, 0.00, 0.00
0.00, 0.00, 0.00

i know im tired but i am seriously stumped

looks like there getting mucked with before i send them im assuming from making a byte array out of them. so question how do i get the floats out of the struct in a way the NRF will accept them or am i missing something with Mirf and the NRF24 it self that is causing me to have to use bytes and not send floats.

welp heading to bed :sleeping:, maybe it will come to me in the morning. :fearful:

Well so far so good maybe? it's late agin 5:18am here need some sleeps got 2 hours on yesterday

think i am getting closer. formatted text is nice but only first field is filling? -0.15, 0.00, 0.00
any guidance would be great i am so far out in uncharted territory for me is unreal. and why am i only getting xx.xx and not xx.xxx ? yes that amount of precision would be handy.
