Troubleshooting
From time to time there may be some snags that can cause what would seem like malfunctions in the
module. If you experience any of the symptoms listed below, here are some quick fixes to try.
Q1. Will not connect to Easy Bluetooth module?
A1. Verify that the Bluetooth device has been properly installed via the Device Manager; there may be
drivers needed depending on the type of Bluetooth dongle/module you are using.
Q2. Bluetooth port isn’t available for selection in the new DEBUG window.
A2. Be sure that the com port is included in the port search for the BASIC Stamp editor; for details on
how to do this, please refer to the BASIC Stamp Help file in the editor (version 2.5 or later)
Q3. Will not power up?
A3. Verify that the module is connected correctly and that Vdd and Vss have not been swapped.
Q4. Receiving Easy Bluetooth connection LED (green) blinks, but no information is displayed on the
DEBUG screen?
A4. If the receiving modules LED is blinking, then there is a completed connection and the setting in the
debug window is not set properly. Verify that the correct com port and baud rate is selected in the
terminal window. If com port does not come up, please see A2 above.
Q5: What if I don’t have a Board of Education with an AppMod Header; can the Easy Bluetooth be used
with the HomeWork Board or a breadboard?
A5: Yes you may. There are 4 connections needed to correctly connect the Easy Bluetooth module to a
microcontroller, the Rx, Tx, Vss (ground) and Vdd (+5VDC). Here is an example that connects the Easy
Bluetooth module to the HomeWork Board, but could as easily be another type of controller with the
provided connections. Here are two pictures with the connections made to a HomeWork Board. Please
keep in mind, the connections match the example program provided.
