uvicMuse not starting on Osx 11.0.1

[soreno123]

Hello, i've got a MUSE-02 and since i'm unable (apparently) to use my BLE usb dongle, i'm trying to use uvicMUSE with the internal Bluetooth of the Mac (Macbook Pro 2019 16'). But as soon as i start it it crashes with no error message. I've tried

On MacOSx: Application crashes after running:

pip uninstall serial pyserial pip install pyserial esptool

But nothing changed. Any Hint? Thanks, Soreno

Update: I reinstalled uvicmuse and now when i start it i get this error:

Hello, it seems like the problem is caused by Kivy. Try these:

1. Reinstall uvicmuse using the --force-reinstall flag for pip. Also, make sure you are installing the latest version (5.2.1)
2. Follow this instruction to install and compile Kivy: https://kivy.org/doc/master/gettingstarted/installation.html#install-conda
3. I can see that you are using python 3.9.1. If the above solutions do not work, try making a new conda environment with python=3.8

Hello, I've remove python 3.9 and installed 3.8. Now it starts, but when i look for muse it says "No BLE Module Found" That's my BT info. Any hint? Thanks a lot

• First, let's make sure that the terminal has access to Bluetooth. Go to your system preferences and make sure it looks like this:

• Open a python shell (on the same environment as you installed uvicmuse) and write down this code. Post the outputs here.

from uvicmuse.MuseWrapper import MuseWrapper as MW import asyncio loop = asyncio.get_event_loop() M_wrapper = MW (loop = loop, target_name = None, timeout = 10, max_buff_len = 500) M_wrapper.search_and_connect() # returnes True if the connection is successful EEG_data = M_wrapper.pull_eeg() EEG_data = M_wrapper.pull_eeg() print (str(EEG_data)) M_wrapper.disconnect()

Hello, after giving permission to iTerm it worked. Thanks for the support!

Glad to hear that. Closing the issue.
