This is the code for the demonstration of the COVIDSafe exploit in
This has to be run on linux. It uses @abandonware/bleno nodejs module (you need nodejs10), which trivially allows setting advertising bytes for the gatt server.
I run this on Linux Mint, in VirtualBox, adding a USB Bluetooth adapter to pass through. Install the requirements as per bleno's intructions, they are still current.
It runs an express server, with a very simple interface:
http://0.0.0.0:3000/start - starts advertising with exploit advertisement
http://0.0.0.0:3000/stop - stops advertising
A super simple Material Angular application. If you set up a Host-only Adapter for VirtualBox, you can connect to the server in the VM. Simply toggle to hit the APIs. See the site/README.md for details on how to run it.
