I need help writing the code for transfer of txt file to arduino wifi shield using FTP and store data in the sd card. The SD card library has been installed but I am unable to find proper code for linking the data received by the server acting nano to sd card. Please help me with any links or responses thank you. Also is it true that WIFI Shield cannot open data channel and command at the same time if so how can i bypass this ?
Can you post yout existing code?
SD read write code ?
No, the FTP server that you now have.
Also Is it possible to send txt files via cloud to the device and then upload it to sd card. Saw another video where FTP was used to transfer files wireless. The codes are supposed to be on the same line, still researching for them. https://www.instructables.com/Wireless-SD-Card-Reader-ESP8266/
Sorry, I missed the not in that sentence.
I suggest that you start with an FTP server example that you have and get that working with a small text file (e.g. 10 bytes). After that, integration with SD storage should not be too complicated.
I suspect that looking at FTP examples for the ESP family will not really help you. But from the link that you posted, Wireless_SD/ESP8266FtpServer.cpp at master · Neutrino-1/Wireless_SD · GitHub does show how to store on SD.
I don't know anything about cloud so can't help you there.
Note: I have no experience with the Nano33 IoT.

Thanks for the information, but if you know anyone who has experience working with nano iot pls send them this question and get me help. I am searching for articles day and night still not able to find any related. Will try the FTP protocol and get back with codes. Let me know if I can try something then. Thanks
