node.js - 错误：未找到属性 (0x0a) - 当我尝试订阅 Arduino Nano 33 BLE Sense 上的 BLE 特性时
问题描述
我正在使用Noble.js连接我的Arduino Nano 33 BLE Sense。一切正常，而不是订阅。当我尝试通过 订阅时characteristic.subscribe([callback(error)]);，我在 上看到以下内容sudo btmon，相关部分如下：
ACL Data RX: Handle 64 flags 0x02 dlen 9
ATT: Error Response (0x01) len 4
Read By Type Request (0x08)
Handle: 0x0013
Error: Attribute Not Found (0x0a)
如果我们从这里检查标志，它会说同样的事情。我可以通过通用 BLE 应用程序订阅，没有任何问题。那么，我该如何进一步调试呢？
BlueZ 版本是 5.50。
