Modules give Bluetooth connectivity
Kanda has made available serial to Bluetooth modules that can be built-in to any product to give a Bluetooth connection. The modules have a low pin count, 3.3V operation and include an antenna.
TheyThis Bluetooth interface has configurable operating modes and can communicate with any other Bluetooth node such as PDAs, some mobile phones, PC Bluetooth adapters, laptops, or simply talk to each other.
As well as being simple to add to hardware, they are simple to setup using the Windows Manager software supplied with the units or by using AT modem commands. A starter kit is available that is ideal for setup and evaluation of the modules.
There are two module types for Class 1 and Class 2 Bluetooth – the main difference being the signal range. Class 2 modules are 8-pin with an onboard antenna and a range of 30 metres. Class 1 modules have 12 pins. They use an external antenna and 15cm extension cable, which is easy to mount outside a case, and have a range of 100 metres with the supplied stub antenna. Extra range can be achieved using optional Dipole or Patch antenna.
As both the Bluetooth mode and the serial port are easy to configure and change, including Baud Rate, parity, Hardware Flow control, Generic Access Profile and many others, then these modules can fit into a range of existing designs without major re-engineering. So, the range of uses is endless from serial cable replacement to product updates via Bluetooth.
