Error 812 with CPU WMP50

Legacy Open AT
1

Hello,

I try to open a ftp client with the following commands,

AT+WIPCFG=1 -> OK
AT+WIPBR=1,6 -> OK
AT+WIPBR=2,6,11,“xxxxxxxx” -> OK
AT+WIPBR=2,6,0,“xxxxxxxx” -> OK
AT+WIPBR=2,6,1,“xxxxxxxx” -> OK
AT+WIPBR=4,6,0 -> CME ERROR 812

I try to send SMS and everything is OK (the module works) but when I try the ftp software, I always had ERROR 812.

Do I need to do some setting ?

Can someone help me ?

Thanks,
Regards .

Stephane

Hi,
Did you check your module is registered to the network?
CME ERROR 812 means “bearer connection failure : GPRS network failure”.

So i will suggest you to make sure your module’s registration status.

Oups, I change my module’s registration and it work fine… thanks

But I have another problem ! I have a connection with my FTP server and I use the following command :

AT+WIPFILE=4,1,2,"./test.txt"

I have the anwser : CONNECT

And nothing else during long time and then

+CME ERROR 841.

On the server I have a text file (test.txt) but it is empty.
is someone have an idea ?

Thanks

It seems some issue with your FTP connection… are you able to download files successfully from FTP?

Yes, I try

AT+WIPFILE=4,1,1,"./test.txt"

And everything is ok. I can download the file on the SD card ??

OK<\r>AT+WIPFILE=4,1,1,"./test1.txt"
CONNECT
