Question: Why does HelloClient.exe report the error message: "Broadcom Bluetooth profile pack for Windows (BTW) has to be installed"?
Step 1: The first thing you need to ensure is you have the Bluetooth (WIDCOMM) drivers installed. If you have a folder in ~Program Files called WIDCOMM you are probably okay. If not, get them from: http://www.broadcom.com/support/bluetooth/update.php
Step 2: If Step 1 does not fix the problem, make sure you are using WICED-Smart SDK Version 1.0.1 or later. Version 1.0.0 may report this error even if WIDCOMM drivers were installed. If you dont know what SDK version you have installed, open the file (inside the SDK): ~WICED-Smart-SDK/version.txt
