CircuitPlayground.readCap() not working with Bluefruit.begin()

Operating System

MacOS

IDE version

Arduino 2.2.1

Board

CircuitPlayground Bluefruit

BSP version

1.5.0

Sketch

Simple captouch example works correctly as long as Bluefruit.begin() is commented out.

// Demo program for testing library and board - flip the switch to turn on/off buzzer

#include <Adafruit_CircuitPlayground.h>
#include <bluefruit.h>

// we light one pixel at a time, this is our counter
uint8_t pixeln = 0;

void setup() {
  Serial.begin(9600);
  Serial.println("Circuit Playground test!");

  CircuitPlayground.begin();
  Bluefruit.begin();
}

void loop() {
  // turn off speaker when not in use
  CircuitPlayground.speaker.enable(false);

  // test Red #13 LED
  CircuitPlayground.redLED(HIGH);
  delay(100);
  CircuitPlayground.redLED(LOW);

  /************* TEST CAPTOUCH */
  Serial.print("Capsense #3: "); Serial.println(CircuitPlayground.readCap(3));
  Serial.print("Capsense #2: "); Serial.println(CircuitPlayground.readCap(2));
  Serial.print("Capsense #0: "); Serial.println(CircuitPlayground.readCap(0));
  Serial.print("Capsense #1: "); Serial.println(CircuitPlayground.readCap(1));
  Serial.print("Capsense #12: "); Serial.println(CircuitPlayground.readCap(12));
  Serial.print("Capsense #6: "); Serial.println(CircuitPlayground.readCap(6));
  Serial.print("Capsense #9: "); Serial.println(CircuitPlayground.readCap(9));
  Serial.print("Capsense #10: "); Serial.println(CircuitPlayground.readCap(10));
  delay(1000);

}

Adafruit Forum Thread

What happened ?

All captouch reads are maxed out when BLE is enabled. Should this work or is BLE always going to prevent captouch from being used?

How to reproduce ?

leave Bluefruit.begin() uncommented.

I made an PR to fix this, but it is the bug of CircuitPlayground library https://github.com/adafruit/Adafruit_CircuitPlayground/pull/70. Would you mind trying out the PR while it is on reviewed and post your result there.

PS: I am not sure while enabled bluefruit library cause this to occurs, it should always occur though.

@hathatch - Thank you. I will try this today.

This #70 PR for Adafruit_CircuitPlayground looks good. I'm seeing clear response to captouch and the values are no longer maxed out at 65k values.

thank you for testing it out.
