0刷 ESP32 的问题

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^th 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!
