Arduino ArduinoBLE - BLECharacteristic()用法及代碼示例

創建一個新的 Bluetooth® Low Energy 特性。

用法

BLECharacteristic(uuid, properties, value, valueSize)
BLECharacteristic(uuid, properties, stringValue)

BLEBoolCharacteristic(uuid, properties)
BLEBooleanCharacteristic(uuid, properties)
BLECharCharacteristic(uuid, properties)
BLEUnsignedCharCharacteristic(uuid, properties)
BLEByteCharacteristic(uuid, properties)
BLEShortCharacteristic(uuid, properties)
BLEUnsignedShortCharacteristic(uuid, properties)
BLEWordCharacteristic(uuid, properties)
BLEIntCharacteristic(uuid, properties)
BLEUnsignedIntCharacteristic(uuid, properties)
BLELongCharacteristic(uuid, properties)
BLEUnsignedLongCharacteristic(uuid, properties)
BLEFloatCharacteristic(uuid, properties)
BLEDoubleCharacteristic(uuid, properties)

參數

  • uuid: 16 位或 128 位 UUID String 格式
  • properties: 屬性掩碼 (BLEBroadcast, BLERead, BLEWriteWithoutResponse, BLEWrite, BLENotify, BLEIndicate)
  • valueSize：(最大)特征值的大小
  • stringValue: 作為字符串的值

返回

  • 新的BLE特點與指定UUID和值

示例


// Bluetooth® Low Energy Battery Level Characteristic
BLEUnsignedCharCharacteristic batteryLevelChar("2A19",  // standard 16-bit characteristic UUID
    BLERead | BLENotify); // remote clients will be able to get notifications if this characteristic changes
