I got tired of operating "blind" when working with those inexpensive serial bluetooth modules, so I wrote a utility that helps with testing them as well as reprogramming the name/pin/baud.
The program is called Serial Bluetooth Helper and will work with any Propeller connected Bluetooth module. Since I have a bunch of these going toward some new users, it is included with a guide to help a new user get started. You can access the module from a Propeller terminal program using connected VGA monitor and keyboard, and access it from the programming port using Tera Term.
