The development environment used by this project is the Apache Cordova. Cordova is a open-source mobile development framework that allows you to develop cross-platform applications. That means you can code once and deploy the application in many system, including iOS and Android. Cordova provides an easy way to develop for iOS and Android.
This project can be freely distributed using the MIT Free Software model.

The video below shows you this project working.
Si4735 receiver prototype controlled by iPhone via Bluetooth
This example uses an old iPhone 5C. However, you can use your current iOs or Android device to run it. Thanks to Cordova development environment, you can do it with no code changes.
The screenshot below shows the mobile application interface.
Arduino Shield Bluetooth (HM10 - HMSOft TineSine)
The Bluetooth 4.0 used here is the HM10 (TinySine). It is very similar to the famous HC-05. The photos below show the HM10 Bluetooth. This kind of Bluetooth works well on iOs and Android based device. You also can use the HC-05 Bluetooth device. However, the HC-05 will not work on iOS devices.

Bluetooth Arduino Library
The Arduino sketch of this example uses the SoftwareSerial library. You have to download and install this library on your Arduino enviroment.
The photos below show the Arduino, SI4735 and the Bluetooth devices connections.
Homebrew Si4735 shield
The photo below shows a homebrew version of the SI4735-D60 citcuit with all basic components connected on a SSOP24 board adapter. You need 3 wires to connect the Arduino to the Si4735 board (SDIO, SCLK and RESET). You also can use the Arduino board to power the homebrew SI4745 shield.

The tables below show the wire and pin connections between the Arduino Board and SI4735 and Bluetooth shields.
|Si4735 pin||Arduino Pin|
|RESET (pin 15)||12|
|SDIO (pin 18)||A4|
|SCLK (pin 17)||A5|
Bluetooth shield and Arduino Pro Mini/3.3V/8MHz
The schematic below shows a very simple Arduino, SI4735 and Bluetooth shield setup.
You can use the HC-05 or HC-07 Bluetooth devices instead HM10 on Android based mobile devices. However, these devices will not work on iOS devices.

- PU2CLR Si4735 Library for Arduino. This library was built based on “Si47XX PROGRAMMING GUIDE; AN332” and it has support to FM, AM and SSB modes (LW, MW and SW). It also can be used on all members of the SI47XX family respecting, of course, the features available for each IC version;
- PU2CLR SI4844 Arduino Library. This is an Arduino library for the SI4844, BROADCAST ANALOG TUNING DIGITAL * DISPLAY AM/FM/SW RADIO RECEIVER, IC from Silicon Labs. It is available on Arduino IDE. This library is intended to provide an easier interface for controlling the SI4844.
- PU2CLR AKC695X Arduino Library. The AKC695X is a family of IC DSP receiver from AKC technology. The AKC6955 and AKC6959sx support AM and FM modes. On AM mode the AKC6955 and AKC6959sx work on LW, MW and SW. On FM mode they work from 64MHz to 222MHz.
- PU2CLR KT0915 Arduino Library. The KT0915 is a full band AM (LW, MW and SW) and FM DSP receiver that can provide you a easy way to build a high quality radio with low cost.
- PU2CLR BK108X. The BK1086 and BK1088 are DSP receivers from BAKEN. The BK1088 is a BROADCAST FM and AM (LW, MW and ) RECEIVER and BK1086 is a subset of the BK1088 (it does not have LW and SW acording to the Datasheet).
- PU2CLR RDA5807 Arduino Library. The RDA5807 is a FM DSP integrated circuit receiver (50 to 115MHz) with low noise amplifier support. This device requires very few external components if compared with other similar devices. It also supports RDS/RBDS functionalities, direct auto gain control (AGC) and real time adaptive noise cancellation function.
