RS232 Bluetooth 2.1 Serial Adapter Communication Expansion Module

I bought 2, 1 didn't even transmit any signal so it didn't work at all. The second one would connect with my device but would not transmit the data through the RS232 terminal. Once i bypassed the terminal I couldn't send the data to my device. I could talk to the device but it wouldn't talk back.

I ordered this item to extend my knowledge of Bluetooth devices in conjunction with Android software. I was informed at order time that it would take about 6 weeks for delivery but it arrived in about 3 weeks. I would definitely use this supplier for further purchases. I thought the price was very competitve especially as it comes from the other side of the world with free delivery. If I require any other items like this then i would use this supplier again.
