我最近需要设置一个新的 ESP32 设备来扩展我的工厂监控 BLE 网络. 我打了一个或 2 这样做的问题值得注意
Firstly it turns out some USB to Mini-USB cables just don’t have the data wires connected at all. So if you connect the device and its power light comes on but windows doesn’t detect a new device then the cable might be useless. I checked mine with a spare kindle that we had sitting around and confirmed no data. 该 4日 cable I found finally worked
Secondly it turns out even some cables that do support data still don’t work properly. Tips online say some makes of cable have a capacitor or something embedded somewhere. If you are using “esp-home flasher” you might get an error that looks something like
esp32 Unexpected error: could not open port 'COM10': PermissionError(13, 'Access is denied.', None, 5)
再次, if you hit this, try a different cable!
