2.2  FTP OPERATIONS  

 
 
A set of AT commands is available to support the FTP activities. The fist command is called #FTPTO 
(FTP Time-Out) which defines the time-out for FTP operations. The module has already a factory 
default time defined that is 10 s. 
 
If it is needed to be modified, the syntax is: 
 
AT#FTPTO[=<tout>] 
 
Parameter: 
<tout> - time-out in 100 ms units 
 
100..5000 - hundreds of ms (factory default is 100) 
 
NOTE: The parameter is not saved in NVM. 
NOTE: if parameter <tout> is omitted the behaviour of Set command is the same as Read command. 
 

Example:

 

AT#FTPTO=1000<cr> 

(set the timeout to 100sec) 

OK 
 

2.2.1 Opening and Closing an FTP Connection 

 
With the command AT#FTPOPEN=<server:port>,<username>,<password>,<mode>  is possible to 
open the FTP connection. 
 
The parameters are:  
<server:port> - string type, address and port of FTP server (factory default port 21). 
<username> - string type, authentication user identification string for FTP. 
<password> - string type, authentication password for FTP. 
<mode> 
  0 - active mode (default) 
  1 - passive mode 
 
In order to close the FTP connection the AT command AT#FTPCLOSE should be used.
