0 – normal sending of data chunk
1 – close data port after sending data chunk
The device responds to the command with the prompt <greater_than><space> and
waits for the data to send.
When <bytestosend> bytes have been sent, operation is automatically completed. If
(all or part of the) data are successfully sent, then the response is:
#FTPAPPEXT:<sentbytes> OK
Where <sentbytes> are the number of sent bytes. Note: <sentbytes> could be less
than <bytestosend>
If data sending fails for some reason, an error code is reported.
AT#FTPAPPEXT=? Test command reports the supported range of values for parameters < bytestosend >
and < eof >
Example AT#FTPOPEN="IP",username,password
OK
AT#FTPPUT=<filename>,1
(the new param 1 means that we open the connection in command mode)
OK
Here data socket will stay opened, but interface will be available (command mode)
AT#FTPAPPEXT=Size
>... write here the binary data. As soon Size byte are written, data are sent and OK
is returned
#FTPAPPEXT:<SentBytes> OK
........
Last #FTPAPPEXT will close the data socket, because second (optional)
parameter has this meaning:
AT#FTPAPPEXT=Size,1
>... write here the binary data. As soon Size byte are written, data are sent and OK
is returned
#FTPAPPEXT:<SentBytes> OK
If the user has to reopen the data port to send another (or append to the same) file,
he can restart with the FTPPUT (or FTPAPP).
Then FTPAPPEXT, ... to send the data chunks on the reopened data port.
