Send UDP data to a specific remote host extended - #SSENDUDPEXT
#SSENDUDPEXT – send UDP data to a specific remote host extended
AT#SSENDUDPEXT=
<connId>,
<bytestosend>,
<remoteIP>,
<remotePort>
This command permits, while the module is in command mode, to send data over
UDP to a specific remote host including all possible octets(from 0x00 to 0xFF)
As indicated about #SSENDUDP:
UDP socket has to be previously opened through #SLUDP / #SA, then we are
able to send data to different remote hosts.
Like #SSENDEXT, the device responds with the prompt ‘> ‘ and waits for the
data to send, operation is automatically completed when <bytestosend> have been
sent.
Parameters:
<connId> - socket connection identifier 1..6
<bytestosend> - number of bytes to be sent 1-1500
<remoteIP> - IP address of the remote host in dotted decimal notation, string
type: “xxx.xxx.xxx.xxx”
<remotePort> - remote host port 1..65535
AT#SSENDUDPEXT=?
Test command reports the supported range of values for parameters
<connId>,<bytestosend>,<remoteIP> and <remotePort>
Send Data in Command Mode - #SSEND
