RC7620 Can not use FTP

Hi @jyijyi


I try again.Still have some problem.

did you enter

AT+KCNXCFG=1,“GPRS”,“APN”,"",""

Hi @jyijyi ,

We use AT+KCNXCFG=1,“GPRS”,“internet”,"","" it looks fine.

But we use AT+KFTPCNX=1 then got the result is 911.

So what should I do for download or upload test file ?

And other question How can I query ftp server ?

no problem is found here
is it happening on other network?

Hi @jyijyi

We only have this network. We can use this network to connect internaet on Windows.

Hi @jyijyi

Confirmed baud rate is 115200 but still error.

Is it happening at all protocol?
HTTP?FTP?TCP?

Did you disconnect the USB cable?

Hi @jyijyi

We are using FTP and USB and the result is the same.

i remember i saw error when connecting USB cable in Windows PC…

Is it happening at all protocol?
HTTP?FTP?TCP?

Hi @jyijyi

I am trying to connect in Linux. Now I can’t receive files using ftp.
Can ftp receive zip files?

I don’t see there is “+KFTP_IND: 1,1” which means successful connection to FTP

Hi @jyijyi

I try again but still responds +CME ERROR: 3

how about
AT+KFTPRCV=1,“dummy_file.txt”,0

Hi @jyijyi

Still responds +CME ERROR:3

why do you use …“test_001m.zip”
didn’t you should use comma?

Hi @jyijyi ,
Thanks for your reply.

The server only provide .zip file for download.
So you mean the command only can receive .txt ?

i mean this:

Hi @jyijyi

Sorry,I made a rookie mistake.
Now I connect.
But where can I find my received file or path.

It should appear like this:


AT+KFTPRCV=1,,,"dummy_file.txt",0
CONNECT
11111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111
