Part 1 – AT Commands for All Universal IP Devices

Chapter 1 – General AT Commands for All Universal IP Devices

#LEGACYMODE – Legacy Mode Enable/Disable

About Legacy Mode:

Note: This command is for all devices except the SocketEthernet IP (MT100SEM-IP)

Legacy mode allows for smoother transition to TCP/IP based connectivity from standard analog interface connections.

When #LEGACYMODE=1, the stack will be in pseudo legacy mode where the commands &S, &D, &C, A, D, S0, E, V operate independently of the stack. The commands will be saved to a different NVRAM location and will not affect the IP stack once legacy mode has been exited.

Once in legacy mode, the user can configure the #TCP values and issue an ATD command to make a connection to the remote host. If necessary, the user can also issue ATDxxxxxxxxxxxxppppp where x is the decimal address and ppppp is the remote port. The stack will perform the physical connection and present the user with the proper messages:

 

NO CARRIER

 

NO ANSWER

 

CONNECT

 

OK

Description:

ERROR

If legacy mode is enabled, the AT interface tries to behave like a legacy analog modem. ATD and

 

ATA will function on the TCP stack instead of the physical connection. Responses will behave like

 

that of an analog modem.

Syntax:

Set Value: AT#LEGACYMODE=1

 

View Values: AT#LEGACYMODE?

Values:

0 Disable legacy mode

1Enable legacy mode

Default: 0

#RESET – Reset Main Processor or Internal Modem

Description:

This command will force a reset on the Stack and internal radio or just the internal radio.

Syntax:

AT#RESET =<value>

Values:

0 Reset the Stack and internal modem

 

1 Reset the internal modem only.

 

Note: This value is not valid for the SocketEthernet IP (MT100SEM-IP) and the

Example:

SocketWireless Wi-Fi (MT810SWM-IP)

AT#RESET=0

Note:

After issuing AT#RESET, it can take up to 45 seconds before the MT810SWM-IP is ready to

 

accept AT Commands. When configuring the MT810SWM-IP using security mode WPA or

 

WPA2, the bootup time will take longer.

#SHIELDCHAR – Configure the Shielding Character for DLEMODE

Description:

This parameter defines the shield character for the clients that use shielding (also known as DLE

 

shielding with regards to UIP).

 

Note: This command is for all devices except the SocketWireless Wi-Fi (MT810SWM-IP)

Syntax:

AT#SHIELDCHAR=[<parameter1>]

 

AT#SHIELDCHAR?

Values:

0-255(an integer value between 0 and 255)

Responses:

\r\n#SHIELDCHAR: VALUE\r\n

 

\r\nOK\r\n

 

\r\nERROR\r\n

Examples:

send: AT#SHIELDCHAR=20\r

 

 

reply: \r\nOK\r\n

 

send: AT#SHIELDCHAR?\r

 

reply: \r\n#SHIELDCHAR: 20\r\n

 

reply: \r\nOK\r\n
