AT Commands Interface Guide
Protocol Specific Commands
HL7518 and HL7548
Write command
Syntax
AT+KUDPSND=
<session_id>,
<udp remote
address>,
<udp_port>,
<ndata>
Response
CONNECT
OK
Error case
NO CARRIER
+CME ERROR: <err>
+KUDP_NOTIF: <session_id>,<udp_notif>
Parameters
<session_id> UDP session index
<udp remote address> IP address string or explicit name of the remote host
<udp_port> UDP peer port. Numeric parameter with range 1-65535
<ndata> Number of bytes (max value 4294967295)
<udp_notif> See command AT+KUDPCFG
Reference
Sierra Wireless
Proprietary
Notes
User must use <EOF pattern> to finish sending, then module returns to command
mode.
All the data will be sent out ignoring <ndata>. If data sent is not equal to <ndata>
then KUDP_NOTIF would appear.
<ndata> is the data size without <EOF pattern>.
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.
Using “+++” can abort sending data and using ATO[n] to return back to data mode.
The maximum transmission unit (MTU) is 1500 bytes.
The <udp remote address> and <udp_port> are saved internally such that they can
be omitted in subsequent calls of +KUDPSND.
The packet segmentation is controlled by +KIPOPT with <option_id>=0, and the
maximum UDP packet size is limited by <send size v4> (1472 bytes) or <send size
v6> (1452 bytes). Default values are 1020 bytes.
