Frequently Asked Questions
Question:
My robots appear to be operating normally, but why will my eb500 not
connect?
Answer:
Check the battery power to the robot. Although the motors may still run, the
voltage from the batteries may have fallen well below 5V preventing the
eb500 from operating normally.
Question:
I changed the baud rate on my eb500 to 115200 and persisted the setting. I
am unable to communicate at that speed from my BASIC Stamp. How can I
reset the value to 9600 baud?
Answer:
You can reset the eb500 module to its factory default settings by shorting Pin
8 and Pin 9 and applying power to the eb500 module. Alternatively, if you
have an eb600 PC Adapter you can modify and persist a new setting using
your PC, since the PC is capable of communicating at 115200 baud.
Question:
How do I obtain eMbedded Visual C++ 4.0 to develop Pocket PC
applications?
Answer:
The eMbedded Visual C++ 4.0 development tool is available from Microsoft.
In addition, you will need eMbedded Visual C++ 4.0 SP2 and the SDK for
Windows Mobile
™
2003-based Pocket PCs. These tools can be downloaded
free of charge from the Microsoft Windows Mobile web site:

.
Question:
Why is my eb500 not displayed when I try to discover it from my PC or iPAQ?
Answer:
Verify that the eb500 module is properly powered. Check the battery power to
the robot. It is likely you will discover the eb500 on the first attempt; however,
because Bluetooth discovery is not deterministic, discovery on the first
attempt is not guaranteed. On the PC or iPAQ, use the refresh option to
search for devices again. Verify that the discoverable mode setting in the
eb500 is set to on.
