<h1>Tips & tricks</h1>
<h2>Bluetooth connection problems</h2>
<p>In case of impossibility to establish bluetooth connection, please make sure:</p>
<ul>
<li>Bluetooth daemon <strong><a href="http://linux.die.net/man/8/bluetoothd">bluetoothd</a></strong> is started with <strong>-C</strong> option</li>
<li>You have enough permissions to register SDP service</li>
</ul>
<p>To fix first issue it needs to correct
<strong>/lib/systemd/system/bluetooth.service</strong> or
<strong>/etc/init.d/bluetooth</strong> file (depends on distro) and restart bluetooth service
with the commands like (depends on distro again)</p>
<p><code>systemctl restart bluetooth</code> or </p>
<p><code>service bluetooth restart </code></p>
<p>To check issue with permissions just run command</p>
<p><code>sdptool search --bdaddr local SP</code></p>
<p>If you see something like</p>
<p><strong>Failed to connect to SDP server on FF:FF:FF:00:00:00: Permission denied</strong></p>
<p>then you need to run anyRemote using
<a href="https://www.sudo.ws/">sudo</a></p>
<h2>Enhance security with password</h2>
<p>In <a href="setup-server.html">Server-mode</a> it is possible to set password which will be requested from J2ME/Android clients.</p>
<p>To make this it needs to run anyRemote with <strong>-password</strong> commandline option.</p>
<p>The password phrase should be stored in <strong>$HOME/.anyRemote/password</strong> file in a plain text.</p>
<h2>Keepalive messages</h2>
<p>If J2ME/Android client on the phone disconnects from PC after some inactivity period it is possible to send keepalive messages to
handle this. It just needs to add command like</p>
<pre>Timer(_PING_,300,0);</pre>
<p>to the <strong>$HOME/.anyRemote/hook_connect</strong> file and add command</p>
<pre>Timer(_PING_,cancel);</pre>
<p>to the <strong>$HOME/.anyRemote/hook_disconnect</strong> file.</p>
<p>In the line above <strong>300</strong> is a number of seconds between <a href="conf-server.html#sec-get">Get(ping)</a> requests.</p>
<h2>Customization of client initialization/exiting and connect/disconnect commands.</h2>
<p>It is possible to add custom commands to <a href="ev-handlers.html">(Init)</a>, <a href="ev-handlers.html">(Connect)</a>,
<a href="ev-handlers.html">(Disconnect)</a> and <a href="ev-handlers.html">(Exit)</a> event handlers.</p>
<p>To do this it needs to create file</p>
<ul>
<li><strong>$HOME/.anyRemote/hook_int</strong> (for (Init) event handler)</li>
<li><strong>$HOME/.anyRemote/hook_connect</strong> (for (Connect) event handler)</li>
<li><strong>$HOME/.anyRemote/hook_disconnect</strong> (for (Disconnect) event handler)</li>
<li><strong>$HOME/.anyRemote/hook_exit</strong> (for (Exit) event handler)</li>
</ul>
<p>and put all needed commands there. That commands will be executed after commands defined in appropriate
<a href="ev-handlers.html">event handler</a> command sequence.</p>
<h2>Support for non-UTF8 encodings</h2>
<p>Anyremote J2ME client supports only <a href="http://en.wikipedia.org/wiki/UTF-8">UTF8</a> encoding.
If You system configured to use other encoding (e.g <a href="http://en.wikipedia.org/wiki/ISO_8859-15">ISO-8859-15</a>
used in Western Europe) then it is possible to handle this.</p>
<p>It needs to define variable <strong>$(FromEncoding)</strong> and add command like </p>
<pre>Make(var,FromEncoding,by_value,ISO-8859-15);</pre>
<p>to the <strong>$HOME/.anyRemote/hook_init</strong> file.</p>
<p>Conversion from specified encoding to <a href="http://en.wikipedia.org/wiki/UTF-8">UTF8</a> will be automatically applied
to the following commands:</p>
<pre>ExecAndSet(list,add|replace,...);
ExecAndSet(iconlist,add|replace,...);
ExecAndSet(filemanager,add|replace,left|right...);
</pre>
<p>Reverse conversion to specified encoding from <a href="http://en.wikipedia.org/wiki/UTF-8">UTF8</a> will be automatically applied
to the <a href="vars.html#params_index">$(Param)</a> environment variable.</p>
<p><strong>Note:</strong> Be sure <a href="http://www.gnu.org/software/libiconv">iconv</a> library is installed in You system.</p>
<p><strong>Note:</strong> anyRemote should be compiled with <a href="http://www.gnu.org/software/libiconv">iconv</a> support.</p>
<h2>Volume control with <a href="http://alsa.opensrc.org/index.php/Amixer">amixer</a> or
<a href="http://linux.die.net/man/1/pacmd">pacmd</a> utilities.</h2>
<p>If managed application does not allow to control volume, then anyRemote will use <a href="http://alsa.opensrc.org/">ALSA</a> or
<a href="http://www.pulseaudio.org/">PulseAudio</a> directly. And using of the
<a href="http://www.pulseaudio.org/">PulseAudio</a> will be a preferred.</p>
<p> In this case it needs to have <strong><a href="http://alsa.opensrc.org/index.php/Amixer">amixer</a></strong> or
<strong><a href="http://linux.die.net/man/1/pacmd">pacmd</a></strong> utilities installed on Your system.</p>
<p>By default anyRemote will control</p>
<ul>
<li><strong>Master</strong> channel of soundcard <strong>#0</strong> in case of <a href="http://alsa.opensrc.org/">ALSA</a></li>
<li><strong>Default Sink</strong> in case of <a href="http://www.pulseaudio.org/">PulseAudio</a></li>
</ul>
<p>If it needs to control sound volume with non-default parameters, it is possible to add definitions of the following
<a href="vars.html">variables</a></p>
<ul>
<li><strong>$(default_mixer_up)</strong></li>
<li><strong>$(default_mixer_down)</strong></li>
<li><strong>$(default_mixer_mute)</strong></li>
<li><strong>$(default_mixer_get)</strong></li>
<li><strong>$(default_mixer_set)</strong></li>
</ul>
<p> to the <strong>$HOME/.anyRemote/hook_init</strong> file.</p>
<p>For example, default setup for <a href="http://alsa.opensrc.org/">ALSA</a>:</p>
<pre>Make(var,default_mixer_up,by_value,amixer sset Master,0 5%+ -q);
Make(var,default_mixer_down,by_value,amixer sset Master,0 5%- -q);
Make(var,default_mixer_mute,by_value,amixer sset Master,0 toggle -q);
Make(var,default_mixer_get,by_value,amixer sget Master,0|\
grep '\['|head -1|cut -f 2 -d "["|cut -f 1 -d "]"|sed "s/%//");
Make(var,default_mixer_set,by_value,amixer -q sset Master,0 );</pre>
<p>or default setup for <a href="http://www.pulseaudio.org/">PulseAudio</a>:</p>
<pre>Make(var,default_sink,LANG=C;pactl stat|grep "Default Sink"|cut -f 2 -d ":"|tr -d ' ');
Make(var,default_mixer_down,by_value,$(CfgDir)/Utils/pulse-audio-ctl.sh down $(default_sink));
Make(var,default_mixer_up,by_value,$(CfgDir)/Utils/pulse-audio-ctl.sh up $(default_sink));
Make(var,default_mixer_mute,by_value,$(CfgDir)/Utils/pulse-audio-ctl.sh mute $(default_sink));
Make(var,default_mixer_get,by_value,$(CfgDir)/Utils/pulse-audio-ctl.sh get $(default_sink));
Make(var,default_mixer_set,by_value,$(CfgDir)/Utils/pulse-audio-ctl.sh set $(default_sink) );</pre>
<h2>Power Management</h2>
<p>By default anyRemote will use</p>
<ul>
<li><strong>systemctl poweroff</strong> command to switch off computer</li>
<li><strong>systemctl suspend</strong> command to suspend computer</li>
<li><strong>systemctl hibernate</strong> command to hibernate computer</li>
</ul>
<p>In Ubuntu <strong>pmi</strong> utility is available in <strong>powermanagement-interface</strong> package and
it is possible to use <strong>pmi action suspend</strong> command to suspend computer.</p>
<p>If it needs to change default power management parameters, it is possible to add definitions of the following
<a href="vars.html">variables</a></p>
<ul>
<li><strong>$(default_switch_off)</strong></li>
<li><strong>$(default_suspend)</strong></li>
<li><strong>$(default_hibernate)</strong></li>
</ul>
<p> to the <strong>$HOME/.anyRemote/hook_init</strong> file.</p>
<p>For example:</p>
<pre>Make(var,default_switch_off,by_value,poweroff);
Make(var,default_suspend,by_value,pmi action suspend);
Make(var,default_suspend,by_value,pmi action hibernate);</pre>
<h2>Cover Art support by audio player configuration files.</h2>
<p>If anyRemote can not retrieve cover art from application, it try to search it inside directory with file currently played.
(search done with depth equal to 2).
It is user responsibility to store cover art in appropriate directory.</p>
