UniPager

Thomas Gatzweiler, DL2IC, wrote in rust a software, which allows to use unipager on all hardware variants and also provides a webinterface.

You can choose between two methods: The first one uses a script provided by the DAPNET-crew („rund and forget), the second one uses a dapnet repository.

curl http://db0sda.ampr.org/debian/install.sh -sSf | sh -s -- hamnet

curl http://www.afu.rwth-aachen.de/debian/install.sh -sSf | sh -s -- internet

Create /etc/apt/sources.list.d/unipager.list with this content:

deb http://db0sda.ampr.org/debian unipager main
deb-src http://db0sda.ampr.org/debian unipager main

Then execute the following commands:

wget -O - http://db0sda.ampr.org/debian/rwth-afu.key | sudo apt-key add -
sudo apt-get update
sudo apt-get install unipager

Create /etc/apt/sources.list.d/unipager.list with this content:

deb http://www.afu.rwth-aachen.de/debian unipager main
deb-src http://www.afu.rwth-aachen.de/debian unipager main

Then execute the following commands:

wget -O - http://www.afu.rwth-aachen.de/debian/rwth-afu.key | sudo apt-key add -
sudo apt-get update
sudo apt-get install unipager

The software is hosted at https://github.com/rwth-afu/unipager.

You can use github to install the software (please also refer to the README):

git clone https://github.com/rwth-afu/unipager.git
cd unipager
curl https://sh.rustup.rs -sSf | sh -s -- --default-toolchain nightly (installs the rust compiler)
cargo build --release (compiles UniPager)
sudo ./install.sh (installs UniPager)

Please be aware that usage of UART is only possible with deactivated bluetooth interface in the raspberry pi

See: https://www.raspberrypi.org/documentation/configuration/uart.md

UniPager provides a HTTP_server on port 8073. The website shows the log, the type of transmitter and its settings. It also enables the user to config it.

Um Sender anzubinden, you can use as default db0sda. Please be aware, that the transmitter had to be added there before by an admin (please open a support ticket

type hostname IP Port

Internet dapnet.afu.rwth-aachen.de 137.226.79.100 43434

Hamnet dapnet.db0sda.ampr.org 44.225.164.27 43434

If UniPager was installed via repository (method 2), you can use the package manager to update it as usual:

sudo apt-get update
sudo apt-get upgrade

If the software was complied on your own, you can do a „git pull“ for the latest version and compile it again. To update software and rust compiler, you can use

./update.sh

in the UniPager directory. The script updates the rust compiler and also the UniPager itself.

There is also a testing version in the github repository, which can contain new features (but also bugs ). Please use this version only if you know, that you are doing.

Change /etc/apt/sources.list.d/unipager.list :

deb http://www.afu.rwth-aachen.de/debian unipager-testing main
deb-src http://www.afu.rwth-aachen.de/debian unipager-testing main

Then do an update via package manager:

sudo apt-get update
sudo apt-get upgrade

access control is already implemented but will be improved: https://github.com/rwth-afu/UniPager/issues/12

Via Websocket-protocol and a script it is possible to send directly. See the code at https://github.com/dk4pa/UniPager-SendWebsocket.

With commit 5120af3c were statistics added to UniPager. They provide information about status, time slots, message queue and number of sent messages.

Address for this JSON-object: http://unipager_ip:8073/status

For external access you have to open ports 8073 and 8055 in your firewall/forward it in your router. Please configure an access control before (see below)

To protect the webinterface, create the file /var/lib/unipager/password an and add the password there.

Can be accessed with „sudo journalctl -u unipager“.

At the beginning lookup the ID of the sound device:

cat /proc/asound/cards

:

0 [ALSA ]: bcm2835 - bcm2835 ALSA
bcm2835 ALSA
1 [Device ]: USB-Audio - USB Audio Device
C-Media Electronics Inc. USB Audio Device at usb-3f980000.usb-1.4, full speed

In the example above the usb-sound device has the ID 1, so you enter in the UniPager configuration

plughw:1

.

In rare cases troubles (sometimes with pi1 and pi2) with the output level can occur. Then please use an external sound device (see above).
