Arduino ArduinoBLE - BLECharacteristic()用法及代码示例


创建一个新的 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)

参数

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

返回

  • 新的BLE特点与指定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
