I recently bought a PearlBlue module, but can't seem to find data sheets for it anywhere, including on the website I got it (Saelig). Has anyone used one of these before, or know where I can find more information? It's a bit of a black box from my perspective...
I finally managed to find a data sheet for this thing, but I'm still a bit unsure as to how to wire it up. The Pearlblue module has TX, RX, CTS, and RTS pins for serial communication, while the arduino only has TX and RX as far as I can tell. Are the clear/ready to send lines necessary? Am I going to have to use other digital channels for that? Please advise...
