My code works well to upload first file in the loop to ftp. But it hangs once second file is going to be uploaded.
I'm reading the SD card root folder using lib
first I set the ftp connection using connectFTP() to establish also data transfer port. Next I'm calling the fileTransfer(); While loop function works well, until first file is transfered.
Once second file meet If criteria
if (fileTemp != fileName && fileTemp[0] == '1' && fileTemp[1] == '9')
and send the
client.print(F("STOR "));
client.println(fileTemp);
There is no responce.
Serial.println("\nStarting connection to server...");
// if you get a connection, report back via serial:
if (client.connect(config.server, config.ftpport)) {
Serial.println("connected to server");
}
if(!eRcv()) Serial.println("fail");
client.print(F("USER "));
client.println(config.ftplogin);
if(!eRcv()) Serial.println("fail USER");
client.print("PASS ");
client.println(config.ftppass);
if(!eRcv()) Serial.println("fail PASS");
client.println(F("SYST"));
if(!eRcv()) Serial.println("fail SYST");;
client.println(F("Type I"));
if(!eRcv()) Serial.println("fail TYPE I");
client.println(F("PASV"));
if(!eRcv()) Serial.println("fail PASV");
char *tStr = strtok(outBuf,"(,");
int array_pasv[6];
for ( int i = 0; i < 6; i++) {
tStr = strtok(NULL,"(,");
array_pasv[i] = atoi(tStr);
if(tStr == NULL)
{
Serial.println(F("Bad PASV Answer"));
}

unsigned int hiPort,loPort;
hiPort = array_pasv[4] << 8;

Serial.println(hiPort);

Serial.println(F("Data connected"));
}
else {
Serial.println(F("Data connection failed"));
client.stop();

client.println(F("CWD tpv.cba.pl"));
if(!eRcv()) Serial.println("fail CWD");
delay(500);

I moved the PASV part from connectFTP() to fileTransfer() and it helps for loop, but still only max 6KB of file is stored at ftp.
void fileTransfer() {
if (!root.open("/")) {
sd.errorHalt("open root failed");
}
char fileTemp[13];
while (ftpfile.openNext(&root, O_RDONLY)) {
ftpfile.getName(fileTemp,13);
//Serial.println(fileTemp);

client.println(F("PASV"));
if(!eRcv()) Serial.println("fail PASV");
char *tStr = strtok(outBuf,"(,");
int array_pasv[6];
for ( int i = 0; i < 6; i++) {
tStr = strtok(NULL,"(,");
array_pasv[i] = atoi(tStr);
