The GitHub project is kinda old now. The code has been released 6 years ago.

The requirements.txt also just lists pip packages, but without any compatible versions. Therefore, if you nowadays just execute pip install -r requirements, you will install the newest pip packages. The newest flask package is not compatible anymore and will throw the signal error message.

An easy fix is to just downgrade flask to an older package version. I've used flask==0.11 from May 29, 2016, which seems to work.

Installation instructions

cd /opt/
git clone https://github.com/NORMA-Inc/AtEar
cd AtEar 
virtualnenv -p python2.7 venv # create a virtual env for deprecated python2.7
source venv/bin/activate # activate the virtual env
python install -r requirements.txt # install recommended requirements
pip uninstall flask # remove flask, since it is too new and not compatible with AtEar
pip install flask==0.11 # install compatible flask v0.11 from 2016

# run the script
python run.py --iface <interface>

I have a forked repo with updated information.
