【足够强大】ESPHome+ESP32打造通用蓝牙网关，比小米自家的好

lexcao

两个帖子看下来有点儿懵。
把手头的esp32c3刷成普通的ble网关，能把智能门锁接进来吗？

PVVX/ATC_MiThermometer项目里面写道“If you have many BLE devices, the adapter must be able to receive BLE advertisements every 3 ms. UART speeds of 921600 baud and even USB1.1 are not enough to transfer information in binary form in the HCI format. Requires BT adapter with USB2.0 HS. Otherwise, there will be many gaps in the reception.

Do not use ESP32xxx - it cannot work with BLE at normal speed and drains the batteries of all BLE devices when connected!

ESPHome does not work with Bluetooth 5.0 and misses a lot of advertising packets from BLE devices.”
不知这个和丢消息是否有关
以及，有很多开源的以太网esp32项目，我现在在调试的就是用以太网的esp32，不过我目前只是接入小米温湿度计，对消息的即时性要求没那么高，不过之前esp32用WiFi接入时会有wifi连接困难的情况，所以改用以太网接入。

确实是个值得琢磨的说法，虽然我还琢磨不明白
3ms，这是个非常短的时间，不能用esp32的说法也显得很夸张不过ESPHome对蓝牙5.0的支持度确实是个问题

无论如何，对于esp32来说，以太网肯定比wifi更好

我的鹿客 Q2 门锁，广播包，1秒会发两个，用USB 蓝牙接收器抓的话，几乎全部都能抓到，很少丢，esp32 还是 ...

大佬，不好意思，请教一下，你的鹿客门锁如何实现本地接入的？我通过几位大佬的资料，找到了beaconkey,但不知道为啥是40位字符，是还需要怎么转换么？

我是小白，我想问下，按照我的理解，树莓派上既有 Wi-Fi 也有蓝牙，能否自建蓝牙网关呢？目前遇到的问题是不知道为什么 bluetoothctl 没办法连接小米蓝牙开关。
