The Hello Client PC Application
The Hello Client (hello_client) PC application is provided with the SDK to complement the Hello Sensor
(hello_sensor) tag application. It is located here:
<WICED-Smart-SDK>\Wiced-Smart\Apps\hello_sensor\peerapps\Windows\HelloClient\Release
The application is provided as full source code, along with an executable binary that runs on Windows 32-bit
and 64-bit machines.
Run HelloClient.exe. A HelloClient
Select device
window similar to that shown in Figure 8 is displayed. The
window shows a list of Bluetooth device addresses for Hello Sensors paired to the PC. The Bluetooth device
address programmed in the tag is located in:
<WICED-Smart-SDK>\Platforms\BCM20737TAG_Q32\20737_EEPROM.btp.
To change the Bluetooth device address, open the file and modify the
DLConfigBD_ADDRBase
variable.
Select the correct device (if it is not already selected) and click OK to initiate a connection to the tag. The
connection process may take 5–10 seconds. The tag will emit an audible beep when the connection is complete.

The Hello Sensor application provides paired devices the following information:
• A Hello Service (a proprietary service) with two proprietary characteristics:

Read
button on the HelloClient PC application.
– Automatically by pressing the

Allow Notifications
drop-down must be selected to allow automatic notifications).
• The Hello Configuration read-write characteristic is used to configure how many times a LED on the tag
blinks when the
Application
button (see Figure 10 ) is pressed.
• A Device Information Service that provides information including:
• Manufacturer Name
• Model Number
• System ID
• A Battery Service that provides a battery-level indication
