<blocksize>
Execution command permits the user to transfer at most <blocksize> bytes of remote
file, provided that retrieving from the FTP server has been started with a previous
#FTPGETPKT command, onto the serial port.
This number is limited to the current number of bytes of the remote file which have
been transferred from the FTP server.
Parameter:
<blocksize> – max number of bytes to read
1..3000
Note: it’s necessary to have previously opened FTP data port and started download
and buffering of remote file through #FTPGETPKT command.
Note: issuing #FTPRECV when there’s no FTP data port opened raises an error.
Note: data port will stay opened if socket is temporary waiting to receive data
(FTPRECV returns 0 and FTPGETPTK gives an EOF 0 indication).
AT#FTPRECV?
Read command reports the number of bytes currently received from FTP server, in
the format:
AT#FTPRECV=?
Test command reports the supported range of values for parameter < blocksize >
Example
AT#FTPRECV?
#FTPRECV: 3000
OK
Read required part of the buffered data:
AT#FTPRECV=400
#FTPRECV:400
