FTP client

[JPSvdW]

Hi, I want to add an FTP client to my Zephyr project. I am using an nRF52840 with a Quectell BG-96 modem and want to send data to an FTP server. The only library I can find in Zephyr is the TFTP library which does not have much functionality yet. Has anyone been able to maybe use a third-party FTP client library in Zephyr?

I´m in trouble with the same thing. The Nordic SDK Connect have a lib called ftp client (see this link: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/libraries/networking/ftp_client.html). But none example avaliable. I´m working about this now. If we have some updatings, let´s going putting here, ok? Best regards

If you decide to implement ftp client functionality, patches are welcome in upstream for it.

I have interest in using a FTP client on Zephyr as well.
The NRF SDK implementation works on Zephyr 4.3.0, after copying the related source files, adding them on CMakeLists and kconfigs.

https://github.com/nrfconnect/sdk-nrf/tree/main/subsys/net/lib/ftp_client

It depends only on Zephyr libs. I basically had to enable these:

CONFIG_NETWORKING=y
CONFIG_NET_SOCKETS=y
CONFIG_NET_TCP=y

There is a catch though, these files are published under LicenseRef-Nordic-5-Clause
available at:

SDK-NRF license

It states that:

4. This software, with or without modification, must only be used with a
   Nordic Semiconductor ASA integrated circuit.

Is it possible to use this implementation on Zephyr? Could Nordic provide this with a more open license for use in any integrated circuit?

We've decided to upstream our FTP client library (with some tweaks) from NCS, the PR can be found here:
#104316

It includes the library itself and a FTP shell module that serves as a basis for the sample app.
