= FM Transmitter API Usage =

FM Transmitter is controlled by fmtx-middleware program via D-Bus api. Api includes functions to enable transmitter, change transmitting frequency and station name. Please note that available frequencies may vary by sales region and FM Transmitter may be disabled in certain sales regions. Transmitter is also disabled when external devices are connected to Maemo device, excluding charger and Bluetooth devices. When FM Transmitter is enabled, fmtx-middleware will route audio automatically to the transmitter and enforce proper transmission power allowed in sales region. Fmtx-middleware will emit beeping tone when no other audio is being transmitter to comply with legislature. Api documentation is in the fmtx-middleware-doc package.
