- Well, there's an API for FM radio in latest Cascades Beta 2 and PB NDK 2.0.1/2.1. Can somebody use it in order to make real FM radio app ?

And note that this is from 2009, so i think if it was possible (or legal, note the copyright paragraph), it would have been done.08-13-12 04:53 AMLike 0 - Well, hardware for fm radio is present on our wifi playbooks (Texas Instruments WL1283 GPS/WLAN/Bluetooth/FM).

- I'd like to see it too.
I'd pay for an app if the fm chip could be activated.

For other handset manufacturers, the above technical information about a particular chipset having an FM feature generally means nothing. However, RIM has a history of using the headphone cable as FM antenna for their handsets.08-13-12 11:17 PMLike 0
- It's true the chip itself is no indication that the fm will work. The antennae pin has to be connected and driver software of some kind needs to be present. In some android units/roms fm_drv.ko for instance.
Here is a link to someone who has done some nice work with these chips including TI under android. His app let me use the FM chip in my Samsung Galaxy 5 WITHOUT the headphones connected which Samsungs FM player won't do.
Thought I'd throw it out there if anyone is interested.
