ESP8266 上显示旧的 WiFi SSID

Question

我正在使用 RemoteXY 库和在线应用程序制作器开发一个 Arduino 项目。当我尝试使用 phone 登录 wifi 时出现问题。我转到 WiFi 设置，而不是看到 "Ant-Man's Van" 作为我看到的网络名称 "Inkognitic Arduinoitic" - 我使用相同的 esp8266 模块所做的项目的名称。

用于测试的phone：Samsung Galaxy J3 2017

在从 Arduino 刷新新固件之前 IDE 使用 esptool.py 擦除闪存。

通过 pip install esptool 在您的计算机上安装 esptool。
通过esptool.py --port <serial-port> erase_flash擦除闪存。

可以找到该工具的更多详细信息 here。
