Overview

1.3 Basic AT Command Processing Principles

1.3.1 Ports

The ME909u-521 module provides three ports to interact with its host:



MODEM port: simulated using USB, for AT command interaction and establishing data connection.

Port name: HUAWEI Mobile Connect-3G Modem



PCUI port: simulated using USB, for AT command interaction only. Port name: HUAWEI Mobile Connect-3G PCUI Interface



ECM port: simulated using USB, for establishing communication connection. Port name: CDC Ethernet Control Model (ECM)

The ME909u-521 also provides a port for debugging:



DIAG port: Simulated using USB, for DIAG (diagnostic) command interaction (mainly used to debug modules at present).

Port name: HUAWEI Mobile Connect-3G Application Interface

A host controls a module using AT commands. If AT commands are unavailable, a module can be deemed as unavailable.

1.3.2 AT Command Processing Mechanism

A module processes AT commands from the ports (MODEM, PCUI) in series. An AT command can be processed when and only when the previous AT command processing has been completed. If the module is processing an AT command, a new AT command from the same port will be ignored and other commands from other ports will be buffered until the current AT command is processed.

This rule also applies to COM ports converted from USB ports. The processing of an AT command starts when the AT command is entered from the

TE, and ends when the UE (the module) returns all the results in response the command.

All AT commands entered during this period of time will be

ignored.

All AT commands entered during this period of time will be ignored.

Some special AT commands can be aborted by new AT commands. Such special commands are called abortive commands.

The ME909u-521 supports the following abortive AT commands:



The AT+COPS Set command



AT+CLCK

Example:

AT+COPS=1,2,23415 OK

Before the results ofAT+COPS is returned, enter any characters (such as"AT"), the module will terminate the processing of

AT+COPS and returnOK. The

entered characters are used to abort the command only .

Some commands can be executed when SIM card is inserted. It would return to SIM failure if SIM card is not inserted. For more information, see Property Description of related AT in HUAWEI ME909u-521 LTE LGA Module AT Command Interface Specification.

Example: AT+CREG? +CME ERROR: SIM failure

Note:

SIM failure indicate that SIM card is not inserted.

1.3.3 Recommended Timeout Mechanism for AT Commands Processed by a Host

A module processes AT commands in series. Do not send another AT command before the result for the current command is returned or the current command times out (except when the current command is an abortive AT command). The following table lists AT command timeout durations (starting from the time when an AT command arrives at a port).

Table 1-1 AT command timeout duration

After an AT command times out, it is recommended that the host check whether the module is functioning normally. The following procedure is provided for your reference:

1. The host sends AT to the module.

HUAWEI ME909u-521 LTE LGA Module Application Guide

Overview

Issue 01 (2013-07-05)

Huawei Proprietary and Confidential

2. If the module returns failure information, go to step 5.

3. If the module returns success information, the module is functioning normally.

4. If the host times out (the host waits for a response for over 30 seconds) three times when waiting for the response from the module, go to step 5. Otherwise go to step 1.

5. The host deems that the current module does not exist or is unavailable. Close the port, stop sending all AT commands, exit the procedure to determine whether the module is normal, and re-search for modules.
