+ ====== UniPager ======
+===== Intro =====
+Thomas Gatzweiler, DL2IC, wrote in [[https://www.rust-lang.org|rust]] a software, which allows to use unipager on all hardware variants and also provides a webinterface.
+===== Installation =====
+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.
+==== method one - script ====
+=== via HAMNET ===
+<code>curl http://db0sda.ampr.org/debian/install.sh -sSf | sh -s -- hamnet</code>
+=== via internet ===
+<code>curl http://www.afu.rwth-aachen.de/debian/install.sh -sSf | sh -s -- internet</code>
+==== method two - repository ====
+=== via HAMNET ===
+Create ///etc/apt/sources.list.d/unipager.list// with this content:
+<file>
+deb http://db0sda.ampr.org/debian unipager main
+deb-src http://db0sda.ampr.org/debian unipager main
+</file>
+Then execute the following commands:
+<code>
+wget -O - http://db0sda.ampr.org/debian/rwth-afu.key | sudo apt-key add -
+sudo apt-get update
+sudo apt-get install unipager
+</code>
+=== via internet ===
+Create ///etc/apt/sources.list.d/unipager.list// with this content:
+<file>
+deb http://www.afu.rwth-aachen.de/debian unipager main
+deb-src http://www.afu.rwth-aachen.de/debian unipager main
+</file>
+Then execute the following commands:
+<code>
+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
+</code>
+==== compiling the source code on your own ====
+The software is hosted at [[https://github.com/rwth-afu/unipager|https://github.com/rwth-afu/unipager]].
+You can use github to install the software (please also refer to the README):
+<code>
+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)
+</code>
+**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
+===== configuration and webinterface =====
+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.
+{{ :unipager:uni_webinterface.png?direct |}}
+===== addresses for connecting to a dapnet-server =====
+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
+===== Update =====
+If UniPager was installed via repository (method 2), you can use the package manager to update it as usual:
+<code>
+sudo apt-get update
+sudo apt-get upgrade
+</code>
+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  <code>./update.sh</code> in the UniPager directory.  The script updates the rust compiler and also the UniPager itself.
+===== testing version=====
+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// :
+<code>
+deb http://www.afu.rwth-aachen.de/debian unipager-testing main
+deb-src http://www.afu.rwth-aachen.de/debian unipager-testing main
+</code>
+Then do an update via package manager:
+<code>
+sudo apt-get update
+sudo apt-get upgrade
+</code>
+===== access control =====
+access control is already implemented but will be improved: [[https://github.com/rwth-afu/UniPager/issues/12|https://github.com/rwth-afu/UniPager/issues/12]]
+===== sending a message direct via UniPager =====
+Via Websocket-protocol and a script it is possible to send directly. See the code at [[https://github.com/dk4pa/UniPager-SendWebsocket|https://github.com/dk4pa/UniPager-SendWebsocket]].
+===== statistics=====
+With commit [[https://github.com/rwth-afu/UniPager/commit/5120af3c2c2e2f6413f9cd9149b0985a0ff10b78|5120af3c]] were statistics added to UniPager. They provide information about status, time slots, message queue and number of sent messages.
+{{::unipager:unipager_stats.png?direct|}}
+Address for this JSON-object: http://unipager_ip:8073/status
+===== Port forwarding =====
+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)
+===== password for webinterface =====
+To protect the webinterface, create the file ''/var/lib/unipager/password'' an and add the password there.
+===== logfile UniPager on a Raspi =====
+Can be accessed with "sudo journalctl -u unipager".
+===== configuration of USB-sound devices =====
+At the beginning lookup the ID of the sound device: <code>cat /proc/asound/cards</code>:
+<code>
+[ALSA ]: bcm2835 - bcm2835 ALSA
+bcm2835 ALSA
+[Device ]: USB-Audio - USB Audio Device
+C-Media Electronics Inc. USB Audio Device at usb-3f980000.usb-1.4, full speed
+</code>
+In the example above the usb-sound device has the ID 1, so you enter in the UniPager configuration  <code>plughw:1</code>.
+===== troubles with internal raspberry sound card =====
+In rare cases troubles (sometimes with pi1 and pi2) with the output level can occur. Then please use an external sound device (see above).
