@loboris
Regarding network.mqtt -- not a big deal but in my tests the connected_cb when set in mqtts.config does not seem to actually be called when a connection is made.

Dear All,

Is someone was able to transfer large file to /flash ?

If "yes", how did you do ?

On my side i tried with the ftpserver but it crashed even with small files and it corrupt the flash (i like the ftp server which works fine with LOPY and LO1).
I also tried with pye by opening a new file and doing a copy-paste, but it also crashed.
I did not try with ymodem.

Best regards.

Patrick

[EDIT] ymodem seems to works

New update with FTP module implemented in C and running in background will be pushed later totay. Tested with large files (up to 1MB with flash, >10MB with sdcard).

:!: Update
Some modules added and updated, many bugfixes and improvements.

Basic documentation added, it will soon be updated to include more detailed documentation for all added/changed modules and features specific to this port.

New implementation of the FTP server is added, it runs in separate ESP32 task, like Telnet server, check the basic documentation for more info.

Added freq argument to I2C initialization for compatibility with other MicroPython implementations.

Some examples can be found in modules_examples directory.

Dear Loboris,

once again thanks for this awesome work and for your fast answers.

I just pulled the new release, compile and flash an esp32-psram.

The ftp server is present and i can connect to it (with filezilla), i can see the content of "/", but if i try to open "flash" (CWD flash) i have an error 550, and if i try to transfer a file directly in / i also have a 550 error.

Did i miss something to do before compiling ?

Best regards.

Patrick

If that helps,

network.ftp.status()

return :

(7, 0, 'Connected', 'Data: Disconnected')

@patrick.pollet
There are some changes in the default configuration needed for ftp server to work which were not commited.
Sorry about that and thank you for reporting.
The repository is updated now, please pull the changes.
I would also recommend to delete your old sdkconfig, sdkconfig.old and build directory.
Run BUILD.sh menuconfig, build and try again. It should work now. If not, please report again.

:!: Update
  • Some bugs in FTP mudule are fixed.
  • New organization of toolchain and esp-idf directories
  • BUILD.sh now checks for toolchain & esp-idf version
  • Building on MacOS is now fully supported, all needed toolchains are included.
    BUILD.sh detects the OS and unpacks the right toolchains for it.
    Tested on MacOS Sierra.
