Got my Airlift Featherwing last Thursday. After connecting it to a T4.1 I was able to successfully run all of the example sketches I tried. Downloaded SimpleFTPServer from here:
https://github.com/xreef/SimpleFTPServer
This library has an amazing amount of defines it FtpServerKey.h and FtpServer.h. One device I noticed was SAMD that was using WiFiNINA. I created defines for Teensy based on the defines for SAMD board.
In FtpServerKey.h I added:
Code:
// Teensy T4.x with TEENSYDUINO
#ifndef DEFAULT_FTP_SERVER_NETWORK_TYPE_TEENSY
// Teensy T4.x
#define DEFAULT_FTP_SERVER_NETWORK_TYPE_TEENSY NETWORK_WiFiNINA
#define DEFAULT_STORAGE_TYPE_TEENSY STORAGE_SD
#endif
And in FTPServer.h I added:
Code:
#elif defined(TEENSYDUINO)
#define FTP_SERVER_NETWORK_TYPE DEFAULT_FTP_SERVER_NETWORK_TYPE_TEENSY
#define STORAGE_TYPE DEFAULT_STORAGE_TYPE_TEENSY
This is the sketch I am using for testing:
Code:

void loop(void){
ftpSrv.handleFTP(); //make sure in loop you call handleFTP()!!
// server.handleClient(); //example if running a webserver you still need to call .handleClient();
}
Note: I added arduino_secrets.h file to the sketch folder which looks like this:
Code:
#define SECRET_SSID "your SSID"
#define SECRET_PASS "your password"
At this point Filezilla will connect with this message:
Code:
Status: Connecting to 192.168.0.113:21...
Status: Connection established, waiting for welcome message...
Error: Connection timed out after 20 seconds of inactivity
Error: Could not connect to server
The connection is made but there does not seem to be communication between the server and client. It goes into an endless loop in ftpSrv.handleFTP();.
This section shows status always returning 0:
Code:
#if (FTP_SERVER_NETWORK_TYPE == NETWORK_WiFiNINA)
// if (client && !client.connected()) {
// client.stop();
// DEBUG_PRINTLN(F("CLIENT STOP!!"));
// }
byte status;
client = ftpServer.available(&status);
/*

// DEBUG_PRINTLN(status);
More debugging needed
