FM radio
Figure 125 FM radio interface
The FM radio is an integrated circuit, controlled by MCU software through a serial bus interface. The wires of
the headset are used as poles of the antenna, and no other antenna is needed for FM radio reception.
The radio has an automatic band search function, which can search for a strong write/read signal from a
certain frequency. When this is found, data is transmitted to the radio. When the signal strength is low, the
TikuEDGE can read data, which is available until the signal is strong again.
FM radio and Bluetooth are physically placed in the same module, but they function separately and
independently from each other.
Information about the
bluetooth part (page 9–17) can also be found in the System module section.
