Electronic – arduino – How to use Arduino Bluetooth module

arduinobluetoothserialwireless

I am trying to get my arduino working over wireless (via bluetooth). I would like to send serial signal though it via bluetooth, but I am having some difficulty getting the bluetooth module I purchased actually showing up on any of my computer's bluetooth scan.

This is the skimpy datasheet for the module. It was made by someone in China (an individul, not a company – and that is why I do not really understand it)

Any help as to how I can get this connected to my PC would be great. —Thank you—

Here is the bluetooth module that I have…

I have worked with this module before and found that it only appears in a scan if it is in "data" mode. To put the module into data mode you have to drive the mode pin low. However the datasheet neglects to tell you that the module wont actually switch into data mode until the reset pin is pulled. Try driving the mode pin low, pressing the reset button, and then doing a scan again. Something called "HC-..." should appear.
