I have quite a few questions about this device. Firstly, can you program this device to send a PIN code so that it can authenticate with another Bluetooth peripheral? The peripheral I have, has a typical "0000" PIN code that is needed to connect with the device. Next question, can you give this device AT commands without using the USB adapter, perhaps in an Arduino sketch itself? I heard with other devices that you could do AT commands in a sketch but that it was harder to do. I currently only have the V3 Module and an Arduino Nano. Which brings me to my last question, how exactly do I need to connect the tx and rx pins to each device? With most tx and rx I'm told you flip them i.e. (tx nano >> rx BT & rx nano >> tx BT). But I was also told connecting the tx and rx pins to something from an Arduino can cause issues with uploading sketches.
