2. GATT (Generic Attribute Profile) is the standard protocol that regulates the data communication of BLE devices. Fill in the following fields when adding a new method:

• Name Method name
• Characteristic ID: Unique ID that identifies the data
• Service ID Service ID of BLE devices
• Characteristic Type: UUID indicating the type of data (Read, write, etc.) 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).

3. Save your method by clicking the SAVE button.

• Sub Array: Used to select a specific part of the data. For example, click +ADD ACTION > Sub Array to ensure that the first two values read from a device are converted to Byte (divide by 128) and converted to temperature value. Click Symbol Picker in Sub Array.

• In the “Count” field, enter the value “2” since the first two values are requested.

• Click “+ADD ACTION>Arithmetic>Divide” for byte conversion.

• Divide: Allows data conversion by dividing by a specific value. Click the Symbol Picker in Value in Divide and select Action Results>Sub Array to call the value from Sub Array. Then type “128” in the value2 field.
