I just bought the Arduino Uno and the DFRobot Bluetooth V3. I can not get the serial port to communicate between the module and my computer.
The Arduino is set to run at 115200 baud, as well as the serial port on my computer, but there is no communication between the two. I am wondering if it is a problem between my computer and the BT module, or between the BT module and the Uno.
One of the things that I know is that the link is established between the module and my computer (as indicated by the LINK light on the module).
I have seriously tried a lot of things, but any suggestions would be appreciated.
I have tried running the TX on the BT module to the TX on the Uno, and I've also tried reversing the TX/RX connections.
Thanks in advance.
(if you need to know more information, please ask)
EDIT: It seems that I can communicate with the Uno via serial through the USB connection. But I can not use pins 0 and 1 to communicate via serial with the Uno.
EDIT: I have a feeling that I want to blame the Arduino. When I connect the TX on the BT module to the RX on the BT module and view the serial port on my computer, the sent data returns just fine. Somewhere between sending the data from the module and sending data back to the module, there's a problem. Do I need to do something to enable serial on pins 1 and 0?
