i've seen people staring at me when i plug in some cheap FM dongle to my MP3 to play on the stereo. «IS THAT LEGAL? YOU CAN TRANSMIT OVER A BROADCAST?» literally, yes. and I even did it years ago rickrolling a football match in a building with a VCR's coax output. Now with DVB standard, it's going to be more difficult. BUT HEY wouldn't it be cool to have some HDMI dongle that transmits the video of your PC/laptop/console into DVB-T to any screen/TV you want at home? I should make something like that for cheap.

Most bluetooth modules can be used to recieve and transmit FM signals. HTC had for a long time an app they made to take advantage of this, but not the transmit part, but a third party app developer made the transmitter app that could be used on a rooted device, and the radio functionality worked great as long as you had 3.5mm headphones plugged in to act as the antenna, even able to pause and record live radio feed. The last phone I believe they shipped the FM Radio app with was the M10. It would be cool if GS could showcase taking advantage of a Bluetooth module in this way.

Is that specifically to do with the Bluetooth module or is it using some other part of the phone to do it? Phones can take microphones on the 3.5 mm jack so couldn’t it just be using that functionality with the headphone wires acting like an antenna?

@@Diamond_Tiara No, this is a feature that is built into many Bluetooth chips, but not very well known and not very well documented. Look up the Spirit FM Radio which can be used on Android phones with capable chips, or as in HTC phones a replacement for the stock FM radio app. The replacement apps need root access as the OS isn't setup to use the FM but the drivers are already capable. HTC devices Android build is already setup so no root is required, unless you want to broadcast FM signals from the device. Read over this thread on XDA spirit1-spirit2-real-fm-radio-general-thread Here is the datasheet for the Bluetooth chip BCM4356XKUBG found in the HTX M9 and the Google NEXUS that has FM functions built in and the datasheet cover the use and operations of it. alldatasheet CYPRESS BCM4356XKUBG

It does happen. As many others have mentioned, it's fairly common to use an FM transmitter to send audio from things like a cell phone to a car stereo that doesn't have inputs like audio jacks or bluetooth. Those transmitters often use either very low frequencies or very high ones, and by a coincidence some radio stations that I listen to tend to be found very low on the FM band. So every so often when I'm driving in traffic I'll cross paths with someone using an FM transmitter (we usually call them "FM Modulators" when talking about this application) . For just a moment I hear the music or podcast or whatever the other person is listening to. The signals aren't very powerful and don't go very far, so unless you find the other car and nearly drive next to them you won't hear it long, it'll come and go giving you only just enough time to notice it and hear the general nature of what the other person is listening to.
How is this a hack?!? Its literally doing the job these FM transmitters are made to do!

What are the rules for FM or AM transmission in Germany? In India we are legally prohibited and requires special operating licence and designated frequency from the spectrum of FM. Same goes for AM but usually not given anymore. MW transmission is restricted and kinda obsolete as well. Civilians are never granted such licence and only organisations are granted after long vetting process.
