Have no idea though on how responsive RDS would be in "time-critical" navigational terms. Just a thought...
Well for starters, there are no voice prompts for Ovi Maps on Maemo... We can all thank Nokia for that.

Re: FM RDS Notify Application
 
I had some problems with FM RDSnotify. It seems to drain the n900 battery even when not using mediaplayer.

So as a learning exercise I created a small python script that just shows the mediaplayer title/artist/album on RDS.

Note that it uses RDS PS for the artist name and RDS TEXT for title + album.
Code:
#!/usr/bin/env python

#
# A small script to learn and play with python, dbus,
# mediaplayer and FM RDS
#
# Author: Mirakels (marcel@mesa.nl)
# Date: april 2010
#
# Setup dbus connections to mediaplayer en FMTx. Wait for
# signals from mediaplyer and use them to show info on your
# RDS capable audio system. It uses the RDS station name to
# show the artist, and the RDS text field to show album and
# title info of te current song.
#
# Note that mediaplayer also sets RDS when the FM transmitter
# is enabled (at least it does so in PR 1.1.1). But it shows
# artist/album/title as the RDS station name. This will be
# 'overwritten' by this script.
#
# Just run this script in the background from an xterm:
#
#      $ ./mp_rds.py &
#
# When you enable the FM transmitter in mediaplayer
# RDS messages will be send to your radio...
#

import gobject, dbus
from dbus.mainloop.glib import DBusGMainLoop

album  = ""
title = ""

#
# Just some console fun to see what mediaplayer is doing
#
def handle_state(state):
    if (state == 0):
        print "Media player stopped"
    elif (state == 1):
        print "Media player start playing"
    elif (state == 2):
        print "Media player paused"
    elif (state == 3):
        print "Media player transitioning"
    else:
        print "Media player unknown state %d" % state
       
#
# Set RDS info based on mediaplayer tag info
#
def handle_meta(meta, state, data):
    # print "meta change meta=%s, state=%d data=%s" % (meta, state, data)
    global album
    global title
    if (meta == "artist"):
        artist = data
        fmtx_iface.Set("com.nokia.FMTx.Device", "rds_ps", dbus.String(u'%s' % data , variant_level=1))
    if (meta == "title"):
        title = data
        info = title + ' / ' + album
        fmtx_iface.Set("com.nokia.FMTx.Device", "rds_text", dbus.String(u'%s' % info , variant_level=1))
    if (meta == "album"):
        album = data
        info = title + ' / ' + album
        fmtx_iface.Set("com.nokia.FMTx.Device", "rds_text", dbus.String(u'%s' % info , variant_level=1))
       

DBusGMainLoop(set_as_default=True)
#
# Connect to mediaplayer
#
bus = dbus.SessionBus()
bus.add_signal_receiver(handle_state, path='/com/nokia/mafw/renderer/gstrenderer', dbus_interface='com.nokia.mafw.renderer', signal_name='state_changed')
bus.add_signal_receiver(handle_meta,  path='/com/nokia/mafw/renderer/gstrenderer', dbus_interface='com.nokia.mafw.renderer', signal_name='metadata_changed')

# Create connection to FM transmitter

Re: FM RDS Notify Application
 
ANybody tried this with PR 1.2?

Re: FM RDS Notify Application
 
Hi,

I've created this application, looks like it is no more needed with latest firmware to display songs tags on radio car system.

I ve stopped the devel for a moment as i ve some sending text problem when a call occur.

I will try another time this motnh :)

Re: FM RDS Notify Application
 
Any news on a PR1.2 compatible version?

BabelO 2010-06-22 12:43
Re: FM RDS Notify Application
 
It is already compatible on pr1.2 version and look like the pr1.2 did not broadcast natively tags to fm.

So my applciation is needed again

Re: FM RDS Notify Application
 
hi! since version 0.4-1 the fmrdsnotify widget refuses to start after addition to the desktop. even after a reboot the widget doesn't start automatically althogh i can start it from the shell.

anyone else has experienced this behaviour and knows of a solution for that?
