ftp upload: AT^SISS address setting is throwing error | Telit Cinterion IoT Developer Community

Hi, I don't seem to be able to set the address parameter using AT^SISS.
When running the AT-command from the java applet, the debugger hangs and does not tell me anything.
I then used the terminal and configured this:
AT^SISS=0,address,"ftp://a:b\00ftp.test.net"
but the EHS6 on the concept board just outputs ERROR
character set: AT+CSCS?
+CSCS: "GSM"
I'm looking at page 254 of the AT command set reference pdf.
Any ideas?
Many thanks,
Micha

Hello,
have you specified your service type first using AT^SISS=0,srvType,"Ftp" ?

Thanks for your reply, Jedrzej, I did in the java code but not in the terminal, so this lead me down the wrong path. :-)
I'm working on ftp upload using AT-commands (as there does not seem to be a socket connection for this in Java ME) and after having created the connection profile plus the ftp service profile I do this:
System.out.println("opening ftp connection... ");
m_Cmd.send("AT^SISO=0\r", new EHS6.RspListener());
Thread.sleep(30000);
Most of the time I do not get a response but sometimes I get
^SIS: 0,0,2100,"220 Microsoft FTP Service" followed by
^SIS: 0,0,2100,"FTP Login OK" then
^SIS: 0,0,2100,"put 000101-000000.log" then
^SISW: 0,1
^SIS: 0,0,14,"An established connection was aborted, possibly due to a data transmission"
What I really need to do is process the response strings, I just wanted to do it the quick and dirty way to prove our concept.
Anyway, in the AtCmdDemo there are two ways, synchronous and asynchronous. When should I use which? I thought that with many of the commands, especially internet related ones, asynchronous would be the way to go due to varying response times.
It would be good to have this clarified.
Also, going back to the AtCmdDemo code, I understand how to get the response string using the synchronous method (i.e. with the string 'Response') , but how do I do this with the asynchronous method.
Or should I use the synchronous method all the time?
Apologies if this is quite basic but I'm still getting used to Java...
Many thanks,
Micha

Hello Micha,
It all depends on exactly what You are trying to do.
The design is up to You.
The synchronous method is blocking after sending the AT command while waiting for the response.
The asynchronous method uses a Listener which in case of an event which is a response of an AT command prints the response and the response String is also a variable Response but it is a method variable in the ATResponse method of the RspListener.
public void ATResponse(String Response) {
System.out.println("Received asynchronous response:");
System.out.println(Response);
}
Best Regards,
