Hola colegas,
Desde hace una semana soy propietario y dueño de dicho celular y lo
estoy investigando en sus partes desde hacia dentro, conectado por SSH
a través de Wifi o de un cable de USB, por ambos se puede entrar
libremente (hasta hacerse root con 'sudo su') en este servidor pequeño
que corre un núcleo de Android (por
lo de los drivers) y encima de esto un Ubuntu 14.10 (r20) normal. Os adjunto
primeros resultados (en inglés) y un screen que muestra la pantalla del
celular en mi escritorio de KDE4 en mi netbook. Especialmente lo último,
conectar así el celular y mostrar sus funciones en un escritorio, y
a través de esto con un vídeo-beam, es muy útil para dar charlas o
conferencias.
Ya tenemos el tema de una pequeña conferencia en mi próxima estancia.
Un abrazo
matthias

Things to note (unsorted until now) about the BQ Aquaris E 4.5 Ubuntu phone
Matthias Apitz <g...@unixarea.de>
1. the files (pictures, ...) end up in:
~/Downloads
~/Pictures
~/Pictures/Screenshots
~/Pictures/com.ubuntu.camera
~/Pictures/com.ubuntu.camera/image20150329_183823514.jpg
~/Videos
~/Videos/com.ubuntu.camera
~/Documents
you may copy file to ~/Pictures/com.ubuntu.camera/ but the app only accepts
.jpg files;
2. SSH-in is even possible when the device is locked and black; don't know
if this is intention that it does not suspend; the config goes like this
How to get SSH access to the ubuntu-phone:
see also:
http://askubuntu.com/questions/348714/how-can-i-access-my-ubuntu-phone-over-ssh/599041#599041
login via terminal app, you will be user 'phablet' (the password is the
unlock number)
enable SSH service:
$ android-gadget-service enable ssh
fetch your public key to the Phone from some place:
$ wget http://www.unixarea.de/id_rsa.pub
$ mkdir .ssh
$ chmod 0700 .ssh
$ mv id_rsa.pub .ssh/authorized_keys
Now you can look up your IP on the phone and use ssh to connect:
$ ip addr show wlan0|grep inet
from your workstation use:
ssh phablet@<IP from above command>
3. the touchscreen is capacitive (the Openmoko FR is resistive) which makes it
difficult to use some pen;
4. the available disk space is like this:
Filesystem Size Used Avail Use% Mounted on
/dev/mmcblk0p6 2.0G 1.6G 369M 81% /
/dev/mmcblk0p7 4.4G 273M 4.0G 7% /home
5. JPEG fotos are of the following dates:
$ jhead image20150329_183823514.jpg
File name : image20150329_183823514.jpg
File size : 568513 bytes
File date : 2015:03:29 18:39:43
Camera make : bq
Camera model : Aquaris E4.5
Date/Time : 2015:03:29 18:38:24
Resolution : 2448 x 4352
Flash used : Yes
Focal length : 3.5mm
Digital Zoom : 1.140x
Exposure time: 0.030 s (1/33)
Aperture : f/2.4
ISO equiv. : 132
Whitebalance : Auto
Metering Mode: center weight
JPEG Quality : 80
6. USB:
for networking the bq supports tethering via a usb device (run the
following in the terminal app or via adb):
$ android-gadget-service enable rndis
that will switch USB from MTP to tethering and create a 'rndis0' network
device
whith the IP addr 10.42.0.1;
it offers to the connected computer an IP via DHCP (somehow it takes
sometime)
and SSH is fine too as:
$ ssh phablet@10.42.0.1
Welcome to Ubuntu Utopic Unicorn (development branch) (GNU/Linux 3.4.67
armv7l) >
I fill figure out how to permanently set this IP addr inside the Ubuntu,
maybe an DHCP-server on the host side is to much.
$ netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt
Iface
0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0
wlan0
10.42.0.0 0.0.0.0 255.255.255.0 U 0 0 0
rndis0
172.28.23.131 0.0.0.0 255.255.255.255 UH 0 0 0
ccmni0
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0
wlan0
How can I set it as default to rndis enabled?
Oliver Grawert:
ou cant, it is hardcoded on boot to always have working mtp (until
here is a UI option to turn it on or off, we want regular users to
lways be able to exchange files), but you can override it in a user
pstart job that runs at a later point ...
create /home/phablet/.config/upstart/rndis.conf with the following
content:
--------------- snip ------------------
start on started indicator-network
task
script
android-gadget-service enable rndis
end script
--------------- snap ----------------
7. maps && OSM app
unresolved
/home/phablet/.cache/me.yohanboniface.osmtouch/osm_100-1-9-260-172.png
8. capture the MIR screen for presentation, talks etc.
launch on the phone my script ~/cast.sh which will do:
+-----+-----++-----+-----+-----+-----+-----+-----+-----+-----+-----+-----
#!/bin/sh
srcIP=`echo $SSH_CLIENT | cut -f1 -d' '`
port=12345
printf "mirscreencast'ing to %s port %s\n" $srcIP $port
while true; do
mirscreencast -m /run/mir_socket --stdout --cap-interval 10 -s 270 480 -n
6 || break
done | gzip -c | nc $srcIP $port
+-----+-----++-----+-----+-----+-----+-----+-----+-----+-----+-----+-----
the IP addr 10.42.0.64 is the laptop via USB tethering (Wifi seems
to be to poor for the mass data of the frames);
and launch first on the host 10.42.0.64 the presenter script
~/readScreenCast.sh which does:
+-----+-----++-----+-----+-----+-----+-----+-----+-----+-----+-----+-----
#!/bin/sh
# read the 'mirscreencast' from the Ubuntu phone's MIR server
# see there 'cast.sh'
#
# co g...@unixarea.de, April 2015
nc -l 12345 | gzip -dc |\
mplayer -demuxer rawvideo -rawvideo fps=6:w=270:h=480:format=rgba -
+-----+-----++-----+-----+-----+-----+-----+-----+-----+-----+-----+-----
works fine!
to be continued
