433 MHz is a wireless radio band on which compatible household devices send signals. While TVs use infrared light for handling remote control signals, 433 MHz radio waves enable communication with home devices such as motorized blinds from Somfy, KlikAanKlikUit sensors, or socket switches from LightwaveRF.

All IR remotes use the infrared frequency range (300 mHz - 400 gHz). This range should not be confused with the modulation rate (carrier frequency) of the remote control. The remote control codes are sent to the receiver using the modulation rate.

To pair the Bluetooth Remote Shutter, switch the remote switch on and press either the IOS or Android button to activate it. Then open the bluetooth settings on your device and you will see the shutter in your pairing options.

• BLE uses a client/server architecture. One device is a server that provide services. The other device is a client that consumes services. In order to keep the power requirements down, BLE only transmits small packets of information when a change occurs. In the case of the joystick, the joystick device is a server.

• The VR Control Bluetooth Remote Controller has a single joystick with X and Y axis, two trigger buttons in front and six buttons on the handle. Two of the buttons are for power on/off and mode control. The other four buttons can be used for whatever you want.

• The joystick device advertises five services. The only service that we are interested in is the BLE HID (Human Interface Device) service. A BLE service has what are known as Characteristics associated with it. A Characteristic is typically a source of data. The HID service of the joystick has ten Characteristics.

The CY5672 PRoC™ BLE Remote Control RDK provides a production-ready implementation of a Bluetooth Low Energy (BLE) or Bluetooth Smart remote control.

The PRoC BLE remote control has the Invensense INMP441 microphone on-board to capture and stream voice data. INMP441 is a high performance, low power, omnidirectional, MEMS microphone with an industry standard I 2 S interface that eliminates the need for an audio codec.

The most important part of our BLE Central application is the Client module that makes the Central aware of the Services and Characteristics of the target BLE Peripheral device. This makes it possible to read and write to the Characteristics of interest as well as subscribe to Notifications and Indications.
