Could somebody with a rooted Droid and some insight into how Linux bluetooth works try to test if we can enable the FM radio part of WIFI/BT chip (wl1271) in Droids/Milestones.
I downloaded some init scripts from Texas Instruments that should allow enabling the FM part. I don't know if there is any antenna or if the headphones can be used as antenna though. Can't try this out myself as Milestone hasn't been rooted yet and I'm not allowed to use 'hcitool' or 'hciconfig' commands without root.
I have attached the init scripts downloaded from: [h]ttps://gforge[dot]ti.com/gf/project/wilink_drivers/frs/
More information about how to use them: [h]ttp://www[dot]omappedia.com/wiki/WiLink_Connectivity_Project
Files and links are for the Zoom2 development platform which uses same hardware as our phones. Don't know if some config files should be altered also to enable FM radio.
I also found TI's own FM radio test application. Source is here: [http]://git.omapzoom.org/?p=platform/hardware/ti/omap3.git;a=tree and compiled Android image for Zoom platform here: [https]://gforge.ti.com/gf/project/omapandroid/frs/
Haven't got it working though. Actually I don't know if it's easier to try with the HCI commands and scripts found in the bts files or try to get the fmapp working.
There's some ongoing development on the FM radio matter at AllDroid ([http]://www(dot)alldroid.org/viewtopic.php?f=210&t=1412) and DroidForums ([http]://www(dot)droidforums.net/forum/droid-hacks/8870-droid-includes-fm-receiver-transmitter.html).
