3.13.15. AT#SSEND - Send Data in Command Mode
This command is used to send data through a connected socket.
AT#SSEND=<connId>[,<Rai>]
Execution command permits, while the module is in command mode, to send data through a
connected socket.
After entering AT#SSEND=... command, and terminated the command line with <CR>, the module
returns the following four characters sequence prompt, and waits for data to send:
<CR><LF><greater_than><space> (see IRA character set: 13, 10, 62, 32)
To send the entered data, enter Ctrl-Z char (0x1A hex); to abort the operation enter ESC char
(0x1B hex).
If data are successfully sent, the command returns OK. If data sending fails for some reason, an
error code is reported.
Parameters:
Selection on which Socket connection identifier
send data.
Socket connection identifier supported
RAI (Release Assistance Indication) configuration
Set RAI to: "No further uplink or downlink data transmission subsequent
to this transmission"
Set RAI to: "Only a single downlink data transmission and no further
uplink data transmissions subsequent to this transmission"
The maximum number of bytes to send is 1500 bytes; trying to send more data will cause
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 will be cancelled (and BS char itself will not be sent).
RAI (Release Assistance Indication) is supported in NB-IoT only, otherwise is ignored.
