BluetoothLE


Bluetooth Low Energy, also referred to as Bluetooth LE or simply BLE, is a new communication protocol similar to classic Bluetooth except that it is designed to consume less power while maintaining comparable functionality. For this reason, Bluetooth LE is the preferred choice of communication with IoT devices that have limited power resources. Starting with Android 4.3, Google introduced built-in support for Bluetooth Low Energy. The BluetoothLE extension requires Android 5.0 or higher to avoid known issues with Google's Bluetooth LE support prior to Android 5.0.

  • RssiChanged – Trigger event when RSSI (Received Signal Strength Indicator) of found BluetoothLE device changes

  • ShortsReceived – The ShortsReceived event is run when one or more short integer values are received from a connected Bluetooth device. Depending on the sign parameter of the last call to ReadShorts orRegisterForShorts for the given serviceUuid and characteristicUuid, the shortValues list will contain numbers ranging from -32768 to 32767 (signed = true) or 0 to 65535 (signed = false).
    Parameters:
    • serviceUuid (text) — The unique identifier of the service passed in the read or register call.
    • characteristicUuid (text) — The unique identifier of the characteristic in the read or register call.
    • shortValues (list) — A list of values read from the device. The range of each value will depend on the sign flag previously specified in the call to read or register.

  • ShortsWritten – The ShortsWritten event is run when one or more short integers values are written to a connected Bluetooth device. shortValues will be a list of values actually written to the device. This may be different if the original input was too long to fit into a single transmission unit (typically 11 shorts).
    Parameters:
    • serviceUuid (text) — The unique identifier of the service passed in the read or register call.
    • characteristicUuid (text) — The unique identifier of the characteristic in the read or register call.
    • shortValues (list) — A list of values written to the device.

  • StringsReceived – The StringsReceived event is run when one or more strings are received from a connected Bluetooth device. Depending on the utf16 parameter of the last call to ReadStrings orRegisterForStrings for the given serviceUuid and characteristicUuid, the stringValues list will contain either a UTF-16 little endian decoded (utf16 = true) or UTF-8 decoded (utf16 = false) strings. The string length is limited by the maximum transmission unit (MTU) of the Bluetooth device, which is typically 23 bytes.
    Parameters:
    • serviceUuid (text) — The unique identifier of the service passed in the read or register call.
    • characteristicUuid (text) — The unique identifier of the characteristic in the read or register call.
    • stringValues (list) — A list of values read from the device. The strings will be decoded as UTF-16 or UTF-8 based on the utf16 flag previously specified in the call to read or register.
when BluetoothLE1 StringsReceived serviceUuid characteristicUuid stringValues do
  • StringsWritten – The StringsWritten event is run when one or more strings are written to a connected Bluetooth device. stringValues will be a list of values actually written to the device. This may be different if the original input was too long to fit into a single transmission unit (typically 22 bytes).
    Parameters:
    • serviceUuid (text) — The unique identifier of the service passed in the read or register call.
    • characteristicUuid (text) — The unique identifier of the characteristic in the read or register call.
    • stringValues (list) — A list of values written to the device.
