Bluetooth Introduction
Bluetooth is a wireless protocol for transfering lots of data quickly. As it is a standard, wireless Bluetooth devices from different manufacturers can communicate with each other. This is achieved by using Profiles. Each type of device, for example, headsets, phones, serial port products have their own profile.

So, a device that needs to connect a PC USB port to all types of Bluetooth wireless devices should support as many profiles as possible. On the other hand, a Bluetooth wireless device that replaces wired serial ports would just support Serial Port Profile. Ideally it should allow multiple connections to create a Bluetooth wireless network or allow simple connection between two devices to replicate a serial lead.

Kanda sell both USB and Serial to Bluetooth adapters, as well as Bluetooth IP gateways for Ethernet connection. We also supply embedded serial to Bluetooth wireless modules for Bluetooth enabling your own products.

USB to Bluetooth Adapters
Kanda supply two USB to Bluetooth adapters. Both can connect to a wide range of Blueooth devices. One is a good quality standard USB to Bluetooth adapter, with a range of 10's of metres. The other is a much longer range device, with different antenna options to give up to 1Km.

Serial to Bluetooth
Another Sena Bluetooth wireless line we carry is designed for Bluetooth wireless enabling serial port (RS232) products. This could be a simple cable replacement with a wireless link created by pairing two Bluetooth units together. SD1000 and SD1000U have a button that can lock two devices together without lots of configuration.

Another setup is a Bluetooth wireless network, connected to a PC through USB port

Kanda supply 2 products that can support up to 4 Bluetooth slaves connected to one master. USB to Bluetooth and serial to Bluetooth wireless units are interchangeable in this layout. Both can also be paired. Serial Bluetooth modules (see below)can also connect to the USB Bluetooth wireless unit or Serial Bluetooth product.

Connecting to IP network
If you need to connect to your IP network instead of a PC USB port, the Parani-1000 series are Bluetooth Access Points that provide a Bluetooth wireless to IP Gateway. They are extremely flexible and can be set up very easily to be:
  • A TCP/IP server or client for your host PC
  • A repeater to give extra distance in your network
  • A Bluetooth hub to allow multiple devices to communicate with each other - up to 28
  • Or a LAP interface for direct connection between your Bluetooth devices and ADSL phone lines

This Bluetooth access point can be used in combination with serial to Bluetooth adapters, Bluetooth modules or any other Bluetooth device that supports Serial Port, LAN Access, PAN, Dial up Networking or File Transfer Protocols. You do not need to understand Bluetooth or wireless and you don't need to modify your existing equipment. With setup and management via Internet Explorer, Windows Management Software, Telnet or a Terminal Program, you have all the flexibility you need.

Embedded Bluetooth to Serial Modules
Class 1, class 2 (30 metres) and Bluetooth V2.0 embedded Bluetooth to serial modules to fit in your application. These modules have 8 or 12 pins and are supplied with antenna. Both class 1 and class 2 modules are available with on-board antenna or with an external stub antenna and lead, but alternative antenna are available to give up to 1000m range. V2.0 modules also have a series of antenna choices.
Starter kits are available to get you going with the modules, which can be used in combination with the USB or Serial Bluetooth adapters or Bluetooth IP Gateway described above.

Typical Applications Industrial control and monitoring, sensor networks, building automation, home control and automation, toys, games Wireless LAN connectivity, broadband Internet access Wireless connectivity between devices such as phones, PDA, laptops, headsets



ZigBee Wireless Solution

Bluetooth is very good for fast data transfer, but for control and monitoring applications, you could consider Zigbee Wireless instead, as it is more flexible.
