Using SD card writer and Bluetooth

Other Hardware Storage
1

Hello, I am trying to take data from a sensor and save it to a SD card, with the option to connect via Bluetooth on my phone. I have gotten all the the modules to work separately but I cannot get them to work together.

I can read the data and send it over a bluetooth connection with this code but then nothing is saved to the SD card:

#include <SoftwareSerial.h>// import the serial library
#include <SPI.h>
#include <SD.h>

SoftwareSerial Genotronex(10, 9); // RX, TX
int BluetoothData; // the data given from Computer
const int triggerPin = 5;
const int echoPin = 6;
const int chipSelect = 4;

void setup() {  
  Genotronex.begin(9600);
  Genotronex.println("Will send data ..");
//  // make sure that the default chip select pin is set to
//  // output, even if you don't use it:
//  SD.begin(chipSelect);
}

void loop() {
  long duration, feet, inches, cm;

  pinMode(triggerPin, OUTPUT);
  digitalWrite(triggerPin, LOW);
  delayMicroseconds(2);
  digitalWrite(triggerPin, HIGH);
  delayMicroseconds(5);
  digitalWrite(triggerPin, LOW);
  pinMode(echoPin, INPUT);
  duration = pulseIn(echoPin, HIGH);
  
   // convert the time into a distance
  cm = duration / 29 / 2;

  const byte nVals = 1;  //# of data variables you have
  int var1 = cm; //change to a data variable from sensor

  int data[nVals] = {var1};
  String label = "Var";

//its a loop because this was originally sending more than on variable
  if (Genotronex.available()) {
    for (int i = 0; i < nVals; i++) {
      String stuff = label + i + ": ";
      Genotronex.print(stuff + data[i]);
    }
    Genotronex.println("");
  }
  
  File dataFile = SD.open("DATALOG.txt", FILE_WRITE); //name of file to save data to

//its a loop because this was originally saving more than on variable
  if (dataFile) {
    for (int i = 0; i < nVals; i++) {
      String stuff = label + i + ": ";
      dataFile.print(stuff + data[i]);
    }
    dataFile.println("");
    dataFile.close();
  }
  
  delay(1000);// prepare for next data ...
}

But when I uncommentSD.begin(chipSelect);
It saves to the SD card but the only thing I get over the Bluetooth connection is "Will send data .."

I am using SD Card Writer and Bluetooth module

I am using an Arduino Uno and as far as wiring I have
Bluetooth Module
TXD >> 10
RXD >> 9
SD Card Writer
CS >> 4
MOSI >> 11
SCK >> 13
MISO >> 12

In the example for SD Card Datalogger it has pinMode(10, OUTPUT);
But I wasn't sure if I should include that if I'm using it with SoftwareSerial Genotronex(10, 9);
It looks like SD.begin() is causing the problem but I don't know why. Could someone help me figure out what is causing this?

Thank you,
Tyler

You do include it, pinMode(10, OUTPUT);, and you will be better off connecting the bluetooth elsewhere. You don't need to use software serial anyway, and I bet you don't have a good reason for doing so. So you might use hardware serial.
