Disclaimer: The attached demo code is developed to provide a reference to the customer, it has not been extensively tested. Also, it does not perform all the functionalities included in hello_client app available for Bluetooth devices in WICED SDK.

 

Introduction:

The Hello client demo app available for CYW20706, CYW20719 and CYW20735 in WICED SDK, is designed to connect and access services of the Hello sensor device. This post discusses about an example, which allows WiFi-BT Combo devices to act as a central device (client).

 

Procedure:

Extract the project in the attached zip file ble_hello_client.zip in /43xxx_Wi-Fi/apps/snip/snip/Bluetooth/ directory. Program the device using the ble_hello_client project. After programming, WICED device scans for the available Bluetooth devices. UUID and device name of the ble_hello_sensor project is already defined in application (ble_hello_client.c). WICED device recognizes the desired device and tries to connect to it, invoking the connection up callback.

 

Note that ble_hello_sensor should be running and advertising to test the client functionality. Both Combo and Bluetooth chips can be used for Hello sensor app. Be ensured that the UUID and device name of the Hello sensor device is correctly mentioned in Hello client app.
