Download file from storage

[mohamed-nabil-mohamed]

I tried downloading file from storage about 25kb but it keeps giving me this error :
Download failed, response payload read timed out
meanwhile i tried files about 8kb and it successfully downloaded.
so how can i download large files and i am using esp32 dev Kit v1.

There is no restriction of the file (object) size. The large data upload/download are transferring as chunks.

Most of this problem is because unstable network. You should try to connect via more stable network or the AP which has less devices connected.

You may need to update ESP32 core sdk too.

I tried but this error happens too : Download failed, file I/O error

Read the comments in the examples carefully as it is already guide you how.
