testing led indicator in repowerd

a-help-text

I hope some people can find some time to try my work on led indicator support.
Since I only test on my Oneplus One I am especially curious what happens on other phones.

Sources can be found in the add-light branch of repo https://github.com/wdehoog/repowerd
See also https://forums.ubports.com/topic/3292/support-for-led-notifications/2

How I test:
- make system writable (if you don't know how then stop here)
- edit /etc/init/repowerd.conf and comment out the line with 'respawn'
  (now if you kill the original repowerd it will not be restarted)
- download com.ubports.lightcontrol.conf and save it in /etc/dbus-1/system.d/
  (this handles dbus permissions)
- kill the repowerd process
- download the new repowerd-<hash> binary and make it executable (chmod +x)
- run from a terminal: sudo REPOWERD_LOG=console ./repowerd
  (stop it with ctrl-c)

When done don't forget to uncomment the 'respawn' line in /etc/init/repowerd.conf



First: the 'unread notifications' is not yet supported so it will not work correctly.

In theory it can indicate battery low/charging/full. You can also play with it with dbus (see below)

Show API:
dbus-send --system --type=method_call --print-reply --dest=com.ubports.lightcontrol /com/ubports/lightcontrol org.freedesktop.DBus.Introspectable.Introspect

Activate/Deactivate Bluetooth:
dbus-send --system --type=method_call --print-reply --dest=com.ubports.lightcontrol /com/ubports/lightcontrol  com.ubports.lightcontrol.notifyLightEvent string:BluetoothEnabled int32:1
dbus-send --system --type=method_call --print-reply --dest=com.ubports.lightcontrol /com/ubports/lightcontrol  com.ubports.lightcontrol.notifyLightEvent string:BluetoothEnabled int32:0

Enable playing:
dbus-send --system --type=method_call --print-reply --dest=com.ubports.lightcontrol /com/ubports/lightcontrol  com.ubports.lightcontrol.enableLightEvent string:Playing
dbus-send --system --type=method_call --print-reply --dest=com.ubports.lightcontrol /com/ubports/lightcontrol  com.ubports.lightcontrol.notifyLightEvent string:Playing int32:1

Now play:
dbus-send --system --type=method_call --print-reply --dest=com.ubports.lightcontrol /com/ubports/lightcontrol  com.ubports.lightcontrol.setPlayingData string:0xAAAAAA int32:1000 int32:1000

Done Playing:
dbus-send --system --type=method_call --print-reply --dest=com.ubports.lightcontrol /com/ubports/lightcontrol  com.ubports.lightcontrol.disableLightEvent string:Playing
dbus-send --system --type=method_call --print-reply --dest=com.ubports.lightcontrol /com/ubports/lightcontrol  com.ubports.lightcontrol.notifyLightEvent string:Playing int32:0
