Hello,

my FTP Upload sometimes works, sometimes not. I think there is a problem with the FTP Server, maybe someone can help me to find the Error.

After i configured it, i start the communication:

at^siso=9
OK

^SIS: 9,0,2100,"Ftp open(ftp.***.com:21)"

^SIS: 9,0,14,"An established connection was aborted, possibly due to a data tran
smission time-out or protocol error"
at^sisc=9
OK
at^siso=9
OK

^SIS: 9,0,2100,"Ftp open(ftp.***.com:21)"

^SIS: 9,0,14,"An established connection was aborted, possibly due to a data tran
smission time-out or protocol error"
at^sisc=9
OK
at^siso=9
OK

^SIS: 9,0,2100,"Ftp open(ftp.***.com:21)"
at^sisc=9
OK
at+creg?
+CREG: 0,5

OK

^SIS: 9,0,14,"An established connection was aborted, possibly due to a data tran
smission time-out or protocol error"
at+creg=2

^SIS: 9,0,2100,"FTP Login OK"

^SIS: 9,0,2100,"fput start.txt"

^SIS: 9,0,2100,"FPUT : start.txt 0 bytes"

^SISW: 9,2

^SIS: 9,0,2100,"221 Goodbye."
at^siso=9
