Easy installation and use 1

Pros:
- Relatively easy to access configuration interface (provided you have at least a 3.3V TTL cable and a telnet interface or equivalante)
- Recognized (almost) automatically by Windows 7 (windows update the first time necessary to download drivers)
- No excessive temperature reached at the Blutooth chip (unlike some low cost products), the chips can overheat if no way expected cooling)

Cons:
- Requires 3.3V for power and data lines (not tolerant to 5V !!!! careful)
- Product with no certification (FCC or other)
- Relatively limited communication range (not more than 5m for my case in open space)
- During the driver installation, 2 COM Port apparaise (COM9 and COM10 home) the first being the serial port to use, the second does not react and can cause a crash of the PC application using the port if no Timeout Set for data sent)
