AT+KFTPSND Issue

IoT Modules Legacy HL Series
1

HI,

I’m trying to upload some data as a text file but I seem to be having trouble.

I’m connected with the session but when I send the AT+KFTPSND command I get just ‘ERROR’ so I assume that I don’t have the string correctly formatted…

I’ve tried various different combinations some with " " and some without, with and without Dir folder, different session IDs etc… So please don’t comment unless you have a working string that you have proven as I have read the AT command DataSheet.

Here is my string

AT+KFTPSND=1,Test.txt,1,0

it is my understanding that as +KFTPSND: (1-32),<local_uri>,<server_path>,<file_name>,(0-1),(0-1) does not have the file name in " " they are not required.

I have also tried putting the file name in < > which also returns simply ERROR

I have checked my FTP session control and the sessions are being created and I am getting good connections.

$CSQ: 14,99,-10
+KCNX_IND: 1,1,0
+KFTP_IND: 1,1

If you know where I am going wrong I would be very much appreciated.

Thanks

Hi,

Can you share the AT command logs…? and the notifications what you are getting while starting the ftp and sending the data

First parameter must be wrong. It should be the session id, which you see in

I suggest that you take a look at the FTP client example in section 20.7.1 of the at command guide.

I’ve read the examples which is what I have below… I’ve also set the session ID as 1 and I get exactly the same result.

This is it exactly as per the example but I still get the error, the FTP session is active and I can see this on my hosting FTP session control page.

I have managed to get the module to create the file in the FTP location but Passive or Active FTP connection, I can’t seem to get it to write the data…

I just don’t get CONNECT??

Any help would be much appreciated.

Thanks
