WMP100 resets after FTP


#1

I set up an FTP file transfer like this:

atd99**#
at+wipcfg=1
at+wipbr=1,6
at+wipbr=2,6,11,“nphase.com
at+wipbr=4,6,0
at+wipcreate=4,1,“ftp.mysite.com”,21,“username”,“password”
at+wipfile=4,1,1,"./textfile.txt"

After the ‘wipfile’ command, I get

CONNECT
[contents of file]
OK

Now, here is the strange thing. I have configured ‘AT+WIND=32767’ and after the ‘OK’ response that follows the file transfer, I get the following unsolicited responses:

+WIND: 3

+WIND: 13

+WIND: 1

+WIND: 16

+WIND: 4

+WIND: 10,“SM”,0,“FD”,0,“ON”,0,“EN”,0

+WIND: 11,“07C8C4A701145BAF95275785CC3299C7”,“A2192F76FC247D1744D5DE7C203D5E
6A”

It looks like the processor got reset. Why and how? Sometimes this happens before the transfer is complete. In fact, if the file is over 256 bytes, it is guranteed to be incompletely received, ending in hte modem being reset.

If the transfer direction is outbound, the transfer appears to be normal—I can send multiple blocks of data, then an [ETX], and the file is actually transferred—but the modem resets immediately afterwards.

I am also getting same issue. I am using Q2686 module which reset while trying to connect ftp or after connecting & while transmitting file
