In this demo, we will see how to load the SmartBridge web application and connect with the WICED Sense kit to display sensor data.

1. Downloads and Installations

• Download the es-WiFi demo software and drivers from:

                    www.inventeksys.com/wp-content/uploads/Inventek_Systems_eS-WiFiDemo_v1.4_b2.zip

                         **** DO NOT CHANGE THE LOCATION OF THE WIFI DEMO SOFTWARE ON YOUR PC FROM THE ORIGINAL LOCATION GIVEN                 

• Download the ISM340 SDK patch: http://www.inventeksys.com/wp-content/uploads/Wiced3.1.2patch.zip

                    Install it in the platforms folder:  ...\WICED\WICED-SDK-3.1.2\WICED-SDK\platforms

• Upon installation, you should see the patches in the platforms folder:

     2. Running the ISM GUI

                    Note: If an error or problem occurs for any step throughout the connection process, it is important to unplug the ISM340USB stick, plug it back in and start from the beginning of this tutorial.

• In order to run the ISM GUI go to the following folder: ..\Inventek Systems\eS-WiFi\demo and open the es-WiFI.application
• plugin the ISM340 USB stick into the PC and identify which COMPORT it is
• In the es-WiFi demo GUI, go to Menu > Install Drivers
• Once installation is complete, you should see this screen:

• Go to device manager, click on the correct COM port and change the following settings
  • Baud Rate/BPS: 115200
  • Parity: None
  • Data Width: 8
  • Stop Bits: 1
  • Flow Control: None

• We shall now open the Com Ports: To do so go to Setup > Serial Port > Configure/Open
• You should see the following screen:

• Verify that the correct settings are in place as listed above and press OK to open the COM port.

     3. Setting up the SmartBridge Web Application

               Note***: Before we begin, it is important to note that every command has to be typed into the command line box. After you type in a command and press send, it will always take you to the main window. It is important to go navigate back to the command line to ensure a much smoother process.

• Type in your SSID into the command line box and press send. Once you press send, the program will ask you if the SSID listed above is correct, type in and enter "y" or "n' accordingly.
• Once past this step, type in the correct password. Once again it will ask you if the password that shows on the screen is correct. Give the appropriate response.
• Once your password is entered, enter your security type and press "y". It will automatically generate an IPv4 address for the SmartBridge web application.

• Copy and Paste the given IPv4 address into the internet browser of your choosing. You have now connected to the BT SmartBridge application

     4. Connecting to the WICED SENSE

• We shall connect the ISM-43340 USB stick with the WICED Sense Kit
• We have programmed wiced_sense.c onto the Kit to display all sensor information
• Wake up the WICED Sense Kit and press Rescan on the web application
• You should see the name: WICED Sense Kit along with an address. Connect with the Kit by pressing the "connect" button right next to the address of the Kit
• Once connected, the WICED Sense Kit will show up on the Connection Pairings List. You have now connected the ISM340 with the WICED Sense Kit.

• In order to view the GATT profile, we will press the "Details" button. Once pressed,  the screen should look like this:

We have now completed the Inventek ISM340 SmartBridge Application Demo. For further questions, please refer to the community forums.

WICED Sense Recovery:

1. Connect the USB Cable to the Kit
2. Locate the COM Port enumerated by your PC

The Recovery Process uses either the COM35 or COM36 ports in our case.

In the SDK Make Target, the recover port is COM35 and we edit the WICED Sense Target as shown below:

Before using the SDK to Recover, we need to place the Kit in Recovery Mode by pressing the sequence of Rest and Boot Buttons as follows:

Now we click the Make Target Recovery button and we should see the following:

WICED Sense Modification for Debug:

1. After programming the WICED Sense Kit with your application you will need to remove the resistor highlighted below to add debugging using a TeraTerm Window.
2. Caution: Remember to Re-Install the resistor to reprogram the device.

Procedure for running the WICED Sense TAG on USB Power:

1. Remove the USB cable after you have successfully programmed the Tag
2. Leaving the Battery cover off in this process, press the battery into the battery socket until you see the RED Led turn on

3. While holding the battery with your fingers making the battery connection, insert the USB Cable in the Tag

4.  Release your finger from the battery, letting the battery drop out of the socket and you are now running the Tag from the USB Power

Introduction to WICED Sensors

The following STMicro Sensors are used:

Please refer to the STMicro Web site for details on Sensor Data Sheets.

The iOS App receives notifications in this format:

struct

{

/// Bit mask of sensor data

/// Bit 0: When set, accelerometer included X (2 signed bytes), Y (2 signed bytes) and Z (2 signed bytes).

/// Bit 1: When set, gyro included X (2 signed bytes), Y (2 signed bytes) and Z (2 signed bytes).

/// Bit 2: When set, humidity included (2 unsigned bytes in percentage).

/// Bit 3: When set, magnetometer included X (2 signed bytes), Y (2 signed bytes) and Z (2 signed bytes).

/// Bit 4: When set, pressure included (2 bytes, pressure in mBar * 10)

/// Bit 5: When set, temperature included (2 unsigned bytes, temperature in C * 10).

UINT8    included_sensor_data;

/// sensor data.

/// Data included in the order of the bits set.

/// Max length is 20 bytes, may be smaller when data for only some sensors is included

///        in the notification.

/// Notifications sent out when enabled

/// Notifications for Sensor Notification characteristic value (handle 0x2A)

UINT8    sensor_data[];

};
