Vanaf 1 september is in Nederland de CoronaMelder app beschikbaar. Deze app stuurt bluetooth beacons uit die met de juiste apparatuur en software te zien zijn. Met CoronaTeller maakt Dave Borghuis ism hackerspace TkkrLab uit Enschede deze beacons zichtbaar.
De CoronaMelder is gebaseerd op het DP-3T protocol, voor meer (technische) informatie zie ook mijn blog
De CoronaTeller houd geen gegevens bij, het laat alleen de beacons zien die de laatse 20 seconden zijn gezien.
De CoronaTeller word ook getoond op de expositie van GOGBOT 2020. Er zijn tijdens de GOGBOT 4775 beacons gezien.
From the 1st of September the CoronaMelder app should be available in the Netherlands. This app send bluetooth beacons which are visible with the right hard- and software. With CoronaTeller Dave Borghuis in cooperation Hackerspace TkkrLab Enschede these beacons visible.
The CoronaMelder app is based on the DP-3T protocol, for more technical information see my dutch blog
The CoronaTeller doesn't store any data, it only shows the beacons that are seen the last 20 seconds.
The CoronaTeller is also shown on the GOGBOT 2020. During the GOGBOT there were 4775 beacons seen.
when started you can
- Exposure Notification Beacons wil be scanned and total number showed.
- press spacebar to add 'virtual' beacons
- press q to quit program
- If you want to run it you on a headless system use the "--cli" option
If you don't run on a linux system (and can't use the bleuz stack) you can use a external scanner. For this use an ESP32 as beacon scanner. Check ESP32 Exposure notificaton scanner. Use e.g. " --esp32 /dev/ttyUSB0" to enable this.
- Raspberry 3 or 4
- SD card with : Raspberry Pi OS (32-bit) with desktop, version May 2020. This version include python3, pygame and the bluetooth binarys.
- Screen that is able to handle resolution of 1920x1080 (is hardcode in code).
- be sure you use beacontools >= 2.02 (or you won't see Android phones).
On the first boot of Raspberry Pi startup go trough the Pi welcome wizard (this includes a software update).
All following commands asume that you install it in the home directory of user 'pi'.
If you want to use the beacontools option :
pip3 install beacontools pybluez
sudo setcap 'cap_net_raw,cap_net_admin+eip' /usr/bin/python3.7Take a extra note of the setcap command, if you forget to do this everything seems to work but no beacons wil be seen !! Be sure to install version >=2.02 of beacontools, olders versions contains a bug so you can't see Android phones.
And install the CoronaTeller app by :
cd #make sure that you are in your home dir
git clone https://github.com/zeno4ever/CoronaTeller.gitYou can start the CoronaTeller with command "python3 Coronateller.py"
If you want to start the CoronaTeller every time the Pi reboot execute the following commands:
mkdir ~/.config/autostart
cp ~/CoronaTeller/helper/CoronaTeller.desktop ~/.config/autostart
cp ~/CoronaTeller/helper/start.sh ~In the Raspberry Pi Desktop menu, under 'Preferences', -> 'Raspberry Pi Configuration' you might set the following settings :
- System tabpage
- Change Password : change the default is a good practice
- Hostname : change the host name to find it back in your network eg to 'coronateller'.
- Display tabpage
- screenblanker : Disable if you want the screen always on.
- Interfaces tabpage
- SSH and/or VNC : Enable for remote access if needed.
- Performance tabpage
- Overlay File System : Overlay Enable and Boot Partition Read-only (do this as last option).
To check what beacons is visable to bluez / os
$ bluetoothctl
[bluetoothctl]scan.transport le
[bluetoothctl]scan.uuids 0xfd6f
[bluetoothctl]scan onI included testtool 'testbeacontool.py' so you can see what the scanner will see.
If you want to use it commercial please contact me for the possibilities. You want to have your own CoronaTeller but don't know how to make this contact me, for a small fee I can create one for you.
