Hello,
This part of the forum is in English, please post in English. You have a French part here.
Anyway, you have all information you are looking for about Bluetooth in LabVIEW here.
Bluetooth is a wireless technology that uses a radio frequency of 2.4 GHz to allow devices to communicate. The range of a Bluetooth connection is between 30 and 40 feet, depending on the device and environmental conditions.
The LabVIEW Bluetooth VIs and functions use RFCOMM, which is a connection protocol the Winsock interface exposes. RFCOMM is simple transfer protocol that emulates serial communication. The RFCOMM interface defines Bluetooth servers and clients.
Creating Bluetooth server and client applications in LabVIEW is similar to creating server and client applications for TCP communication. A Bluetooth server uses the Service Discovery Protocol (SDP) to broadcast the availability of the services the server contains and listens for inbound connections. A client creates an outbound RFCOMM connection to a server. Once the client and server connect to each other, they exchange data until the client or server terminates the connection or until the connection is lost.
LabVIEW supports Bluetooth devices that use the Microsoft Bluetooth driver on Windows XP Service Pack 1 or later only. Refer to the Microsoft Web site for Bluetooth devices that support the Microsoft Bluetooth driver. Most Bluetooth devices use a proprietary Bluetooth driver by default. To use the device with LabVIEW, you must switch to the Microsoft Bluetooth driver. On Windows XP Service Pack 1, you must obtain the Microsoft Bluetooth driver CD from the manufacturer of the device to switch drivers. On Windows XP Service Pack 2 or later, the Microsoft Bluetooth driver is already installed.
