Hi,

I am trying to use the Arduino Sketch in:
https://learn.adafruit.com/adafruit-circuit-playground-bluefruit/ble-uart-controller

I am getting the following error:

The first thing to verify is that all board support packages and libraries are up to date.

[MattPackwood]

I installed them to try this, I have 1.3

[dastels]

OK. I see the line

Code: Select all | TOGGLE FULL SIZE

Multiple libraries were found for "Adafruit_TinyUSB.h"

My guess is that it's picking up an old copy. Search your system for that file that not in /Users/mattpackwood/Documents/Arduino/libraries/Adafruit_TinyUSB_Library/ and delete that copy of the library (not just that one header).

Dave

[dastels]

Alternatively delete all copies/versions of the library you find and reinstall it. Maybe start by uninstalling the one from the library manager in Arduino.

Dave

[MattPackwood]

I completely uninstalled Arduino (using Clean My Mac) and reinstalled (using Homebrew), updated the Adruino library, installed the Adafruit library... same error...

[dastels]

you got rid of all directories in your home dir having to do with Arduino, including any hidden ones (e.g. I have a .arduino15 laying around.

Dave

[MattPackwood]

I have tried that, no joy....

Is there a list of where / what I need to clean up (in case I missed something)

Matt

[dastels]

I have ~/Arduino and ~/.arduino15

Dave

[MattPackwood]

Hmm, I am on an iMac, I have neither...

[dastels]

Hmm, I am on an iMac, I have neither...

Weird. I don't see why it would be that different (I'm on Ubuntu).

Dave

[MattPackwood]

I followed the instructions in https://support.arduino.cc/hc/en-us/articles/360021325733-How-to-do-a-complete-uninstall-of-the-Arduino-IDE and cleaned up my install.

Then I follow the instructions in https://learn.adafruit.com/adafruit-circuit-playground-bluefruit/arduino-support-setup
When I add the feed for the Adafruit Boards (adding

Code: Select all | TOGGLE FULL SIZE

https://www.adafruit.com/package_adafruit_index.json

to the additional boards, I get the error below when I open the board manager.

[dastels]

Have you tried over a period of time (hours). I've seen it be unreachable at times. It's the internet, after all.

Dave

[MattPackwood]

I swapped to using:

http://adafruit.github.io/arduino-board-index/package_adafruit_index.json

And got:
