Building Automation eHouse . home control by BlueTooth

BlueTooth is a relatively new , wireless transmission protocol that allows to connect to various types of equipment , ensuring the relative safety of the communication .
BlueTooth provides communication Peer to Peer (device to device) .
Transmission protocol is fully implemented in devices that interface and allows you to:

pairing
encryption
authentication devices

BlueTooth communication can be implemented in many types of devices:

Mobile Phones
PDA
PC
Tablets
Modules BlueTooth/RS232
Printers

For direct control of the home and building automation eHouse BlueTooth module, you can use transparently performing the SPP mode (conversion BlueTooth/RS232 TTL) .
BlueTooth module connects to RoomManager ' and by joint enlargement RS232TTL .
Such a connection allows modules dissipate BlueTooth BlueTooth increasing coverage to the entire surface of the house , building , housing .
Additionally, the Bluetooth module (dongle) can be connected to a PC server, which is a system of working eHouse BlueGate software for receiving control commands in the standard eHouse .
Communication is initiated from the control panels , mobile phone , PDAs with software control eHouseMobile (Windows Mobile) and eHouseRemoteManager (Java Mobile MIDP 2 . 0) .
The transmission is received by the first detected within the Bluetooth module and forwarded by the controller or the PC room .
All modules must be paired BlueTooth and authorized control panels with BlueTooth , that the transmission was transparent and did not require manual approval and authorization .

Advantages and disadvantages of home control by BlueTooth

BlueTooth small transmission range (10m max for Class 2 devices like cell phones , PDAs and other panels)
Additional coverage by reducing the wall , ceilings , chimneys
The need for multiple installations BlueTooth module , to achieve high coverage in the home range
Incompatibility BlueTooth stacks in different management units , from different manufacturers , BlueTooth to constrain some models of PDA , mobile phones . It is necessary to write individual software for BlueTooth stack of the manufacturer
Collision BlueTooth WiFi (work in the same frequency band) with a very large number of WiFi routers, they occupy the whole band
BlueTooth transmission is much less stable than eg WiFi
In newer systems eHouse BlueTooth been completely replaced by WiFi and may be removed from the system due to eHouse nieekonomiczność and limitations of this medium of communication
