Quick start guide
Before you start
1. Register on the Developer Community and
then download and install ModusToolbox™
soware v2.4 (or later) with the Bluetooth®
SDK at
https://www.cypress.com/products/
modustoolbox.
2. Do the following to download and
install the ‘HelloSensor’ code example.
This step will also install the ‘HelloClient’
peer application required later.
a. In Eclipse IDE for ModusToolbox™
soware, select File >New application.
This launches the project creator.
b. In the project creator, click
AIROC™ Bluetooth® BSPs.
c. Select the ‘CYW920721M2EVB-03’
kit and click Next.
d. Click Create and then click Close.
Note: The kit is pre-programmed with the
‘Hello Sensor’ application.
3. Connect a USB cable between the PC and
CYW920721M2EVB-03 (J6) to power the kit.
Run the ‘HelloClient’ application
1. Locate the ‘HelloClient’ peer sample
application that complements the
‘HelloSensor’ application at
…\mtw23\mtb_shared\wiced_btsdk\
tools\btsdk-peer-apps-ble\release-v3.2.0\
hello_sensor\Windows\HelloClient\
Release\x64.
2. Run the HelloClient executable and
select the HelloSensor device, which
appears as a device with the name ‘Hello’.
3. When prompted, allow pairing from
the client to the HelloSensor device.
4. In the HelloClient window, select Allow
Notifications next to the Hello Input
characteristic.
5. Press button SW3 on the evaluation kit.
Observe that the Value field shows the
Hello 1 message.
