我有一个 Android 应用程序，其用户界面包含一个按钮。单击按钮后，我会对与 ESP32 服务器关联的特定 BLE 特性启动写入操作以传输数据。然而，尽管实现了将数据写入特性的代码，但数据并未成功传输到 ESP32。 我从服务器正确接收的数据如下。 UPS%12345678%223%012.8%000%223%00.0%04%1%001%13.5%00.0%00.3%00.0%00.4%000.0%000.0%END 现在我必须将这些数据从 Android 应用程序发送到 esp32。 字符串输入 = builderList.get（1）.toString（） + “%” + “ ON” + “%” + “END”;
