Frequently Asked Questions
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:
http://www.microsoft.com/windowsmobile .
Question:
Why is my eb505 not displayed when I try to discover it from my PC or
Pocket PC?
Answer:
Verify that the eb505 module is properly powered. It is likely you will discover
the eb505 on the first attempt; however, because Bluetooth discovery is not
deterministic, discovery on the first attempt is not guaranteed. On the PC or
Pocket PC, use the refresh option to search for devices again. Verify that the
visible mode setting in the eb505 is set to on.
Question:
I can discover my eb505, but why am I unable to establish a connection?
Answer:
Verify that the connectable mode setting in the eb505 is set to on and that
security is set either to off or open. In closed security mode only devices that
have already established a trusted relationship will be allowed to connect.
Question:
When I try to connect from an EmbeddedBlue device with 1.0 firmware to
one with 2.0 firmware the connection attempt times out and then fails with
Error 2. Why?
Answer:
Version 1.0 firmware did not support passkey security and trusted
relationships, which is enabled as the default in version 2.0 firmware. To
connect from a version 1.0 device you will need to disable security on the
version 2.0 device with the “set security off” command.
Question:
I used the
set visible
command to make the eb505 module not visible to
other devices, but when I perform a scan from my PC I still see the device.
