Implementing the management of Bluetooth Low Energy devices
To implement Bluetooth Low Energy device management in a WINDEV Mobile application, several functions and WLanguage types are available to you.
The principle for using these functions and types is as follows:
  1. Initialize the Bluetooth Low Energy with BTLEInitialize.
    Android This function is useless.
  2. Load the list of accessible devices (BTLEListDevice).
  3. Select the desired device. The status of the connection can be checked by btleDevice Variable >.ConnectionStatus.
  4. If the connection is established with the device, you have the ability to find out the list of its services (<btleDevice variable>.GetAllServices).
    Remark: To get a specific service, use <btleDevice variable>.GetAService.
  5. Select the requested device and load the list of service characteristics (BTLEGetAllCharacteristics).
    Remark: To get a characteristic, use BTLEGetACharacteristic.
  6. Select the requested characteristic. You can:
  7. For each characteristic, you also have the ability to retrieve the associated descriptor. This descriptor describes the data exchanged between two devices compatible with Bluetooth Low Energy: unit of the value, range of values, ... You can:
