gt863-py with ge864 quadv2 sw 10.00.27
I need to know if a ftp server is online in a short time.If the server is offline, as described in ‘"at command reference guide r17 pag. 31", the maximum response time of the command "at#ftpopen" is 100 seconds before receiving the string "error". Can I reduce this value, or is it a fixed value?There is another way to know if a ftp server is offline, in a relatively short time?
you can change the module FTP timeout with AT#FTPTO.
Default is 100 = 10s (unit is 100ms)
it seems not work. These are commands that i used (server ftp offline):
AT#FTPOPEN=xxx.xxx.xxx.xxx, "user", "password", 0
…(over 1 minute passed)…
the same if change timeout values, order, etc.
Fulvio you are right.
In case the TCP/IP SYN pkt doesn’t receive any answer from the
server the TCP/IP timeout is burned to 80 seconds and
cannot be configured thru AT commands.
