上传固件时ESPflasher软件无法识别 bin 文件（即使文件存在且路径为英文）

[baelow]

首先，非常感谢开发这款优秀的工具！软件的 UI 设计非常美观，功能也十分丰富（如串口监视、Flash 擦除、固件写入等），可以说是首款真正打通 Android-ESP32 固件写入与监视功能的软件，非常值得上架 Google Play Store 或 F-Droid！

当前遇到的问题：
软件无法识别 bin 文件，即使：

• 文件确实存在于指定文件夹
• 文件名和路径均为英文
• 已授予所有权限
• 设备连接正常（可读取固件信息）

环境信息：

• 设备：小米 10 Ultra（Android）
• ESP32 连接状态：正常（可读取固件信息）

已尝试的排查步骤：
✓ 已授予所有权限
✓ 重启软件 3 次
✓ 重新插拔 ESP32 3 次
✓ 修改 bin 文件名（如 temp.bin）
✓ 更换存储路径（如 /Download/temp.bin）
✓ 测试最新版和旧版

可能原因：

1. Android 兼容性问题？（似乎不太可能）
2. 其他未知因素

求助：
是否有其他用户遇到类似问题？任何排查建议都将非常感激！也希望作者可以帮助我一下。

Unable to detect bin file during use (even though the file exists and the path is in English)

Description:
The UI of this software is very beautiful, and it offers a wide range of features (including serial port monitoring, flash erasing, firmware writing, and many more). It can be said to be the first software that seamlessly integrates Android-ESP32 firmware writing and monitoring functionality. It really should be uploaded to the Google Play Store or F-Droid.

Current Issue:
Software fails to recognize bin files when:

• File exists in specified folder
• Filename and path are in English
• All permissions granted
• Device connection working (can read firmware info)

Environment:

• Device: Xiaomi 10 Ultra (Android)
• ESP32 connection: Normal (firmware info readable)

Troubleshooting Attempted:
✓ Granted all permissions
✓ Restarted app 3 times
✓ Replugged ESP32 3 times
✓ Renamed bin file (e.g. temp.bin)
✓ Changed storage path (e.g. /Download/temp.bin)
✓ Tested latest and older versions

Possible Causes:

1. Android compatibility issue? (seems unlikely)
2. Other unknown factors

Request:
Has anyone encountered similar issues? Any troubleshooting suggestions would be greatly appreciated! Please help me, dear author.
