Hi, I have the DF Bluetooth v3 module and USB to UART module. I cannot talk to the bluetooth to change or access the settings. Please can anybody give details of how to? The USB to UART module is com9 I use putty and select com9 but nothing. The bluetooth module is in AT mode so I am stuck as to what to do. The bluetooth module works as I can use to drive my df robotshop rover with the test sketch that uses w,a,d,s but instead of usb its over bluetooth so working. Just cannot talk to it via USB to UART to access via AT commands. Appreciated help. Regards.
Hi Dartec,
Welcome to the RobotShop Forum. Which USB to UART converter are you using? It’s important to note that the DFRobot Bluetooth module uses two different lines for Tx and Rx (instead of just one for both). Can you also verify that the V and GND pins are properly connected? An image of your setup would be appreciated. Also note that the default Baud rate for the Bluetooth module is 115200, which you may need to configure in your software. We await your reply.
Sincerely,
