Yesterday I struck out with Bluetooth modules because I picked some that weren't meant to act as a transparent serial port. I had more ready to test, but I wasn't sure which models were the kind I wanted. I grabbed a pair called "HC-06," which was almost correct since they were a simple version that could only wait for a connection and not initiate one. I tested this and connected with an Android phone and an app called Bluetooth Terminal. I had to add the module through my phone's settings first.
I grabbed another module named "HC-05," which can initiate a connection. electroSome's website has a good walkthrough for the module and links to a comprehensive list of available commands. I failed until I read up on how to put the module into the correct mode, which meant holding the "KEY" pin high, which I accomplished by tapping off the ISP cluster of my USB to serial converter. Next, I changed my serial terminal's baud rate to 38400bps, and I could talk with the module in configuration mode. I blundered through the steps and got the modules talking, but I'll need to iron out the steps and put them into pseudo-code.
