Protocol Specific Commands

Error case

+CME ERROR: <err>
+KUDP_NOTIF: <session_id>, <udp_notif>
+KUDP_DATA_MISSED: <session_id>, <ndata missed>
Parameters
<session_id> UDP session index
<ndata> Number of bytes the device wants to receive (max value 4294967295)
<udp remote address> IP address string of the remote host
<udp remote port> Numeric parameter (0-65535)
<ndata available> Number of bytes to be read in first received packet
<udp_notif> See command AT+KUDPCFG
<ndata missed> Number of bytes left (and definitely lost!) in the UDP socket
Reference
Sierra Wireless

Notes
This function is used to receive <ndata> data bytes through a previously opened
UDP socket.
<ndata> indicates the max data number that the terminal wishes to receive. If the
UDP socket contains more data than <ndata> bytes, then only <ndata> bytes will
be received and more data can be read by running this command again.
<EOF pattern> would be added at the end of data automatically.
When <ndata> (max value) bytes or only available data in the UDP socket have
been received, the module returns to command mode.
It is highly recommended to configure the module for hardware flow control using
AT&K3 before using this command.
The behavior of DTR drop meets with AT&D.
