I got a bluetooth sensor from this Chinese company. Model is BC417. The module has six pins:

  • KEY
  • RXD
  • TXD
  • 5.0
  • 3.3
  • GND

I'm totally newbie about GPIO and sensors, only got that module and a few cables. What should I do to start working with it? How should I plug it, and do I need any resistor? What libraries should I download?

At least I want to be able to emit anything through bluetooth or receive any kind of data from a mobile bluetooth device.

I got the module connected, I followed this site straightforward. When I scanned with my mobile for connected devices I found HC-05 which googling I knew it's a an standard for bluetooth module devices.

I already installed bluetooth and bluez-utils on my Pi.

I used Android blueterm app and logged in into my Pi
