Using PhyPhox for lsm9ds1 accelerometer

[ManvirB]

Hi there,

I am using the Nano 33 BLE board to receive accelerometer data to upload onto 3 separate channels. However I am unable to do so, because whenever I write code for the lsm9ds1 my phone cannot find my Arduino via bluetooth. It just doesn't show up. When I write my own code I am able to connect to my Arduino and display two separate channels. I have included my code below, if possible could someone help guide me towards the solution? Thank you so much 




Code:

#include <phyphoxBle.h>
#include <Arduino_LSM9DS1.h>

void setup() {
  Serial.begin(115200);
  PhyphoxBLE:tart("Experiment");

  //Experiment
  PhyphoxBleExperiment Experiment;  //generate experiment on Arduino which plot random values

  Experiment.setTitle("Experiment");
  Experiment.setCategory("Arduino Experiments");

  //View
  PhyphoxBleExperiment::View firstView;
  firstView.setLabel("FirstView"); //Create a "view"
  PhyphoxBleExperiment::View secondView;
  secondView.setLabel("SecondView"); //Create a "view"
  PhyphoxBleExperiment::View thirdView;
  thirdView.setLabel("ThirdView"); //Create a "view"

  //First Graph
  PhyphoxBleExperiment::Graph xGraph;      //Create graph which will plot random numbers over time
  xGraph.setLabel("Graphing x-acceleration");
  xGraph.setUnitX("s");
  xGraph.setUnitY("m/s/s");
  xGraph.setLabelX("time");
  xGraph.setLabelY("x-acceleration");
  xGraph.setColor("FF0000");                //Sets Color of line

  /* Assign Channels, so which data is plotted on x or y axis
    first parameter represents x-axis, second y-axis
    Channel 0 means a timestamp is created after the BLE package arrives in phyphox
    Channel 1 to N corresponding to the N-parameter which is written in server.write()
  */

  xGraph.setChannel(0, 1);

  //Second Graph
  PhyphoxBleExperiment::Graph yGraph;      //Create graph which will plot random numbers over time
  yGraph.setLabel("Graphing y-acceleration");
  yGraph.setUnitX("s");
  yGraph.setUnitY("m/s/s");
  yGraph.setLabelX("time");
  yGraph.setLabelY("y-acceleration");
  yGraph.setColor("00FF00");                //Sets Color of line

  /* Assign Channels, so which data is plotted on x or y axis
    first parameter represents x-axis, second y-axis
    Channel 0 means a timestamp is created after the BLE package arrives in phyphox
    Channel 1 to N corresponding to the N-parameter which is written in server.write()
  */

  yGraph.setChannel(0, 2);

  //Third Graph
  PhyphoxBleExperiment::Graph zGraph;      //Create graph which will plot random numbers over time
  zGraph.setLabel("Graphing z-acceleration");
  zGraph.setUnitX("s");
  zGraph.setUnitY("m/s/s");
  zGraph.setLabelX("time");
  zGraph.setLabelY("z-acceleration");
  zGraph.setColor("0000FF");                //Sets Color of line

  /* Assign Channels, so which data is plotted on x or y axis
    first parameter represents x-axis, second y-axis
    Channel 0 means a timestamp is created after the BLE package arrives in phyphox

  */

  zGraph.setChannel(0, 3);

  //Info
  PhyphoxBleExperiment::InfoField myInfo;      //Creates an info-box.
  myInfo.setInfo("In this view you can set a value between 1 and 10. The squared random value will be multiplied by this value and can be seen here.");
  //myInfo.setColor("404040");                  //Sets font color. Uses a 6 digit hexadecimal value in "quotation marks".

  //Value
  PhyphoxBleExperiment::Value myValue;        //Creates a value-box.

  myValue.setPrecision(2);                    //The amount of digits shown after the decimal point.
  myValue.setUnit("u");                        //The physical unit associated with the displayed value.

  myEdit.setXMLAttribute("max=\"10\"");

  //Export
