Kuika's Is Connected action is used to check whether the Bluetooth device has established a connection with the app. It determines whether a successful connection with a specific Bluetooth device is available. If there is a connection, data can be sent, if there is no connection, a warning can be issued to the user or a reconnection process can be started. In this tutorial, you will learn how to add an Is Connected action to your application.

The Is Connected action only supports mobile applications.

This training content consists of the following topics:

Adding a data source connection to your app via Bluetooth.
Adding a new method for Bluetooth connection to your app.
Adding Is Connected action.

Add Data Source Connectivity to Your App with Bluetooth

After logging in to the Kuika platform, open the Mobile project you will work on from the “Apps” screen.
Go to the “Datasources” (1) module. In the Datasources module, you can view the data sources, actions and tables in the application you have developed, add a new data source, a new action and a new table.

To add a new data source to your application, click on the “+” (2) icon next to the “Sources” heading on the left side of the Datasources module.

Select “Bluetooth” (1) as the Datasources type and give it a name (2).
Then click on the “CREATE” (3) button.

On the screen that opens, fill in the Device Name, Device ID and Device Address fields.

Device Name (1): The name of the device visible to the user.

It is mandatory to enter the Device Name field.

Device ID (2): The unique ID of the device.
Device Address (3): The Bluetooth address of the device. For example, the address of a Bluetooth device: “00:1A:2B:3C:4D:5E.”

It is not mandatory to enter the Device ID and Device Address.

Then click on the “CREATE” (4) button.

Add a New Method for Bluetooth Connection to Your Application

After adding a Bluetooth connection to your app, click on the “ADD NEW METHOD” button in the right corner.

Configure the settings in your application's method from the pop-up that opens.some text
- Name (1): This is the field where the created method name is entered.
- Characteristic ID (2): The characteristic ID is usually used to distinguish each characteristic.
- Service ID (3): GATT defines services that devices can use to represent specific functions or data types.
- Characteristic Type (4): Characteristics, as units under services, represent a specific function or data. Each characteristic is identified by a UUID (Universally Unique Identifier) and can allow operations such as read (Read), write (Write) or mark (Notify or Indicate).
After filling in the required fields, click on the “SAVE” button to create the method.
