invoke FM radio in MIDlet

[chan_fookmun]

is it possible to invoke the FM radio in the java application assuming the mobile device can support it?

[petrib]

I could be wrong, but don't think there's any phone with a built-in FM radio that has a Java API available for doing anything with the FM radio.

In fact, there seems to be a way of accessing the radio from a Java application.

In version 1.1 of the Mobile Media API, support for a radio locator was added.

A section from the description of the javax.microedition.media.Manager class in the MMAPI 1.1 Javadoc:


3. Locators for Radio Tuner

To create a Player to tune into a radio program, the following locator syntax is used:

"capture://radio" [ "?" tuner_params ]


where:

tuner_params = tuner_param *( "&" tuner_param )
tuner_param = "f=" freq /
"mod=" modulation /
"st=" stereo_mode /
"id=" program_id /
"preset=" preset
freq = megahertz /
kilohertz /
hertz
megahertz = pos_integer "M" /
pos_integer "." pos_integer "M"
kilohertz = pos_integer "k" /
pos_integer "." pos_integer "k"
hertz = pos_integer
modulation = "fm" / "am"
stereo_mode = "mono" / "stereo" / "auto"
program_id = alpanumeric ; identifies an FM channel by its
program service name (PS) delivered
via Radio Data System (RDS)**.
preset = pos_integer ; predefined tuning number


** The RDS specification is available from http://bsonline.techindex.co.uk, id BSEN 50067:1998.

Examples:

capture://radio?f=91.9M&st=auto
(91.9 MHz with automatic stereo setting)
capture://radio?f=558k&mod=am
(558 kHz with amplitude modulation)
capture://radio?id=yleq
(FM channel that has "yleq" as its program service name
delivered via Radia Data System)


While testing the media capabilities of different devices using Manager.getSupportedProtocols() and Manager.getSupportedContentTypes(), I have noticed that at least the 6230i should be able to use radio as an audio input using capture://radio. Has anyone tested if the radio functionality really works on the 6230i?

I think this mobile have some errors in firmware or something..
FM-tuner in 6230i doesn't work..
