<h1 id="gnokii-tips">Gnokii Tips</h1>
<p><em>Posted 2007-05-22, updated 2021-07-01.</em></p>
<p>I own a Nokia 6102i phone (provided by Cingular). <a href="http://gnokii.org">gnokii</a> is a Linux program that lets me interface with the phone. Here are some recipes:</p>
<h2 id="file-io">File I/O</h2>
<p><code>gnokii --getfilelist "A:\\predefgallery\\predeftones\\predefringtones\\*"</code></p>
<p><code>gnokii --putfile WiiSports.mp3 "A:\\predefgallery\\predeftones\\predefringtones\\WiiSports.mp3"</code></p>
<h2 id="ring-tones">Ring Tones</h2>
<p>Voice mail picks up in 20 seconds, so a ring tone should be about 20 seconds long.</p>
<p>The easiest way to chop an MP3 in Linux is with <code>dd</code>; the drawback is that you need to specify length in KB, not time. To chop an MP3 to be 200 KB long, do:</p>
<p><code>dd if=Mii\ Channel.mp3 of=MiiChan2.mp3 bs=1k count=200</code></p>
<h2 id="phonebook">Phonebook</h2>
<p>To make a Phonebook.ldif file from the phone (suitable for import into Thunderbird):</p>
<p><code>gnokii --getphonebook ME 1 end --ldif > Phonebook.ldif</code></p>
<p>To add the entries in Phonebook.ldif to the phone:</p>
<p><code>cat Phonebook.ldif | gnokii --writephonebook -m ME --find-free --ldif</code></p>
<p>You can specify <code>--overwrite</code> instead of <code>--find-free</code> if you want to overwrite all the entries, but this will lose some data (e.g. speed dial, preferred numbers).</p>
<h2 id="multimedia">Multimedia</h2>
<p>You can get photos like this:<br>
<code>gnokii --getfile "A:\\predefgallery\\predefphotos\\Image000.jpg"</code><br>
They are 640x480 JPG files. (You can also configure the camera so that it takes pictures at 80x96.)</p>
<p>You can also store files:<br>
<code>gnokii --putfile silly.jpg "A:\\predefgallery\\predefphotos\\silly.jpg"</code><br>
These show up on the phone in <code>My Stuff/Images</code>. The files don’t need to be any specific size; they are autoscaled. GIFs probably also work.</p>
<p>Videos live here:<br>
<code>gnokii --getfile "A:\\predefgallery\\predefvideos\\Video000.3gp"</code><br>
VLC seems to be able to play <code>.3gp</code> files, but the audio doesn’t work.</p>
<p>Audio recordings live here:<br>
<code>gnokii --getfile "A:\\predefgallery\\predefrecordings\\Audio000.amr"</code></p>
<p>Unfortunately, nothing I knew of in 2007 (when this page was first written) would play <code>.amr</code> files, but these days (2021) perhaps <code>ffmpeg input.amr output.mp3</code> would work. You might have to use the <code>-ar</code> flag to specify the audio rate. I haven’t actually tried this though!</p>
