[edit] Vibrator

This is in reference to the vibrator in the Neo FreeRunner, however it is likely identical to the Neo 1973, as best I can tell.

[edit] Controlling

The vibrator is controlled through:

 /sys/class/leds/neo1973\:vibrator/brightness

When off, it will read 0. Valid ranges appear to be 0-255, with 255 being the fastest.

[edit] Vibrate only on Ring

  • OM2007.2

The general means of configuring the ringtone is done in the file /etc/pulse/session:

load-sample ringtone /usr/share/openmoko/sounds/ringtone_class.wav

Without that file, the phone will be silent, but still continue to vibrate on ring. A convenient way is to gzip the ringtone file:

gzip /usr/share/openmoko/sounds/ringtone_class.wav

The pulseaudio daemon (or the phone) will need to be restarted:

/etc/init.d/pulseaudio restart

The second number represents the duration in milliseconds to hold that intensity. Any non digit characters in the file count as a separators between numbers, but are otherwise ignored.

[edit] vibrating with pulses

The way to turn it off is:

echo none > /sys/class/leds/neo1973:vibrator/trigger

For reference, the way to turn it on, is:

echo timer > /sys/class/leds/neo1973:vibrator/trigger
echo 300 > /sys/class/leds/neo1973:vibrator/delay_on
echo 700 > /sys/class/leds/neo1973:vibrator/delay_off

Vibrator

This is in reference to the vibrator in the Neo Freerunner, however it is likely identical to the Neo 1973, as best I can tell.

Controlling

The vibrator is controlled through:

 /sys/class/leds/neo1973\:vibrator/brightness

When off, it will read 0. Valid ranges appear to be 0-255, with 255 being the fastest.
