推荐答案

外设使用至少每 15 分钟更改一次的随机可解析地址，此时外设看起来是新的.要更改此行为，您需要与外围设备配对，然后您将看到 UUID 并且它将是持久的.

The peripheral uses a random resolvable address that changes at least every 15 minutes, at which point the peripheral will appear to be new. To change this behavior you need to pair with the peripheral, then you will see the UUID and it will be persistent.
