MULTISOCKET AT COMMANDS

137 AT Commands for EV-DO-EV3 Modems

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 than 1500 bytes returns an

ERROR.

 #SSEND can be used with #SD or #SL after a socket connection has been established.

 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)

Example

Send data through socket number 2

AT#SSEND=2

>Test<CTRL-Z>

Send Data in Command Mode Extended #SSENDEXT

While the module is in command mode, this execute command sends data through a connected socket.

Test command returns the range of supported values for <connID> and <bytestosend>.

Syntax

Command Command type

AT#SSENDEXT=<connID>,<bytestosend> Execute

AT#SSENDEXT=? Test

Parameters and Values

<connID> Socket connection identifier.

1-6

<bytestosend> Number of bytes to be sent.

To obtain the range use Test command.

The device responds to the command with the prompt ‘>’ <greater_than><space>

and waits for the data to send.

When <bytestosend> bytes is sent, operation is automatically completed.

If data is sent successfully, then the response is OK.

If data sending fails for some reason, an error code is reported.
