Hi Renzo,
Congratulations on the work.
I tried to run the sketch as an attachment (FTP via Access Point) but I couldn’t access the files and I got the following message:
Command is: PASV
Connection management set to passive
Listening at 0.0.0.0:50009
-M-L-S-D- -
Command is: MLSD
List of file!!
Thank you for your attention.
