[0]
No end of data. Other data may follow to be transmitted via the Internet
service.
Note for UDP Endpoint service: Value 0 must be set before
<Udp_RemClient> parameter although <eodFlag> is not effective for UDP
Endpoint.
1
End of data is signalled to the Internet Service. Further AT^SISW write
commands
return an error response. However, reading data may be possible. The
<eodFlag> is effective only if the <reqWriteLength> equals <cnfWrite-
Length>, in particular if the <reqWriteLength> equals 0.
End-of-data flag must be enabled for following actions:
- FTP "cmd","put" (sending single file to FTP server)
- SMTP "cmd","at" (sending attachment from AT command interface)
- HTTP "cmd","post" if "hcContLen" is not equal zero (sending large amount
of data)
< Udp_RemClient >
(str)
Service specific parameter of the AT^SISW write command. If the Socket service is configured as UDP
endpoint this parameter is mandatory and specifies the IP address (in dotted format) and the UDP port of the
remote host. For each write request another IP address and UDP port may be given.
< cnfWriteLength >
(num)
0...1500
Confirmed number of data bytes which can be transmitted via the Internet
service configured in <srvProfileId>. This number may be less or equal to the
value requested with <reqWriteLength>. The application has to deliver exactly
the number of bytes indicated by <cnfWriteLength>. A 0 value means that no
data can be written at this time, i.e. it serves as a flow control mechanism.
< unackData >
(num)
The value is constantly changing until the entire upload job has completed. If the value equals 0 all data sent so
far is acknowledged.
<unackData> includes the <cnfWriteLength> value of the pending write operation. Therefore, the very first
write operation of an upload job returns identical values for <cnfWriteLength> and <unackData>.
This mechanism allows the host application to easily verify whether or not the remote host has successfully
received the data.
Parameter is not applicable to HTTP, SMTP, Socket with UDP protocol. For these services the counter is
always set to 0.
