Adafruit Feather nRF52840 Sense and Plotter Sketch

[mark_lw]

Will the Adafruit Feather nRF52840 Sense work with the Plotter Sketch?

Here is the link to the Plotter Sketch: https://learn.adafruit.com/bluefruit-le-connect/plotter

Have tried to compile the sketch and there is always some type of error. Is it just for the nRF51 board?

Mark,

The Bluefruit_LE_Connect_Plotter.ino example is nRF51 specific and incompatible with the Feather Sense.

You can work with this bit of code and follow the Feather Sense setup procedures to get communication going with the Bluefruit LE Connect App.

Code: Select all

void loop(void) {

  delay(1000);                  //wait 1 second
  uint8_t val = random(0, 255); //find random value
  ble.print(val);               //send value to bluefruit uart

  if (SEND_SECOND_PLOT) {               //change SEND_SECOND_PLOT to 1 for add'l sine plot
    if (sineIndex > 255) sineIndex = 0; //stay within bounds of sine table
    ble.print(",");                     //print delimiter for second plot
    ble.print(sine_wave[sineIndex]);    //print value from sine table
    sineIndex++;                        //increment index
  }

  ble.println();  //print newline so app knows to plot the values

}
