OK
SRING URC (<srMode> be 2, <dataMode> be 0) displaying (in text format) 15 bytes data that have just come
through connected socket identified by <connId>=3. It is not necessary to issue #SRECV to read the data; no data
remain in the buffer after this URC.
SRING: 3,15, stringa di test
Send Data in Command Mode #SSEND
Execute command permits, while the module is in command mode, to send data through a connected socket.
Test command returns the range of supported values for parameter <connId>.
Syntax
Command Command type
AT#SSEND=<connId> Execute
AT#SSEND=? Test
Parameters and Values
<connId> Socket connection identifier.
1‐6 The device responds to the command with the prompt <greater_than><space>
and waits for the data to send.
To complete the operation send Ctrl‐Z char (0x1A hex); to exit without writing the
message send ESC char (0x1B hex).
If data is successfully sent, then the response is OK.
If data sending fails for some reason, an error code is reported.
Notes
„
The maximum number of bytes to send is 1500 bytes. Trying to send more data causes the surplus to be
discarded and lost.
„
It is possible to use #SSEND only if the connection was opened by #SD, else the ME is raising an error.
„
A byte corresponding to BS char(0x08) is treated with its corresponding meaning; therefore previous byte is
cancelled (and BS char itself is not sent)
Examples
Send data through socket number 2
AT#SSEND=2
