I have a few questions about getting a bluetooth device up and running. I've connected the bluetooth mate to an arduino pro mini and have the following questions:
-
When I go to the bluetooth icon in the system tray on my laptop and connect to the bluetooth device, the connection led on the bluetooth mate does not light up, even though my laptop says a connection has been made. In fact, it doesn't light up until I open the arduino software on my laptop. Why is this? Why does the arduino software need to be open for the bluetooth mate to think that it is connected? (it is interesting to note that the connection led stays lit even after I close arduino).

The documentation for the bluetooth component of the bluetooth mate breakout board says that you can only enter command mode within the first 60 seconds of establishing a connection. This can be changed, but this is the default setting. I have not changed these settings at all and yet I am able to enter command mode well after 60 seconds by simply sending the '$$$' code to the device. Why is this? What is going on?
Sorry if this is the wrong place to post this topic or if I'm using the wrong terminology for some of these things. I'm still pretty new at all of this. Oh, and thanks for your help in advance!
