- 1.3 Basic AT Command Processing Principles
- 1.3.1 Ports
- 1.3.2 AT Command Processing Mechanism
- 1.3.3 Recommended Timeout Mechanism for AT Commands Processed by a Host
- Table 1-1 AT command timeout duration
- 1. The host sends AT to the module.
- 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.
- 2 Initialization Application Scenarios
- 3 Serial Port Configuration Application Scenarios
- 4 External Protocol Stack Application Scenarios
- 4.1 Prerequisites
- 4.2 Establishing Data Connections
- 4.3 Data Transmission
- 1. Data can be transmitted after data service connections are established.
- 2. According to 3GPP TS 25.306, HSDPA (FDD) terminals are classified into 24 categories. Different categories have different peak data rates. The following table lists common categories and their key parameters.
- 3. According to the Radio Resource Control (RRC) version, the WCDMA/HSDPA/HSUPA/HSPA/DC_HSPA rate in theory are as follows:
- 4.4 Switch Between Data Mode and Command Mode
- 4.5 Disconnecting Data Service Connections
- 4.5.1 Reference Process
- 1. Terminating a data service connection from the TE: the TE sends a PPP Terminate packet to the UE to pull down the DTR signal. The UE disconnects the PPP connection, releases the wireless link resource, pulls down the CD signal, and returns NO CARRI...
- 2. Terminating a data service connection from the UE: The TE sends an AT command to the UE to pull down the DTR signal. After receiving the AT command, the UE releases the connection to the network, pulls down the CD signal, and returns NO CARRIER. As...
- 3. When disconnecting data service connections in Android RIL, the module must kill pppd to disconnect PPP connections before using AT+CGACT=0 to deactivate PDP contexts and release wireless link resources.

- 2. Changes on the network, for example, an incoming text message, a signal change, a network working mode change, a network search, an IP data package (when a dial-up network connection is set up).
- 3. Software system events such as a timer
- 4. Abnormal events, for example, an antenna drops or a SIM card becomes loose.
- 9.3.5 Host Woken up by Module
- Wake-up Source
- Remotely Waking up the Host Using USB
- 1. The USB controller on the host supports USB remote wake-up and can wake up the host.
- 2. The USB driver enables or disables remote wake-up by executing SET_FEATURE and CLEAR_FEATURE commands. Therefore, remote wake-up must be enabled on the USB driver before USB enters suspended mode.
- 3. When the host receives the remote wake-up signal from the module, the host needs to send a full speed K signal that lasts at least 20 ms. When the USB controller resumes, the host must send the SOF token within 3 ms from the startup of the idle sta...

1.3 Basic AT Command Processing Principles
1.3.1 Ports
The MU609 supports two configurations with USB connection, and the second
configuration will be selected as the default configuration on Linux/Android OS.
NOTE
The first configuration is reserved and not used currently.
The MU609 provides six ports to interact with USB connection as shown in Figure 1-
1 .
The following steps show how to find the six ports.
Step 1 Execute dmesg command.
Step 2 Find the mapping details between the ttyUSBx and the USB port.
Figure 1-1 Port sequence on Linux
- ECM port: simulated using USB, for establishing communication connection.
This is eth2 in Figure 1-1 .

- MODEM port: simulated using USB, for AT command interaction and
establishing data connection. This is ttyUSB0 in Figure 1-1 .
- DIAG port: simulated using USB, for DIAG (diagnostic) command interaction
(mainly used to debug modules at present). This is ttyUSB1 in Figure 1-1 .
- PCUI port: simulated using USB, for AT command interaction only. This is
ttyUSB2 in Figure 1-1 .
- GPS NMEA port: simulated using USB, sending unsolicited indications for NMEA
positioning data only. This is ttyUSB3 in Figure 1-1 .
- GPS Control port: simulated using USB, for GPS AT command interaction only.
This is ttyUSB4 in Figure 1-1 .
NOTE
The number of ethx and ttyUSBx may be different between different operation systems, yet the
port sequence is the same as shown in Figure 1-1 .
The MU609 also provides a physical serial port:
UART port: physical serial port, for AT command interaction and establishing data
connection.
A host controls a module using AT commands. If AT commands are unavailable, a
module can be deemed unavailable.
1.3.2 AT Command Processing Mechanism
A module processes AT commands from the ports (MODEM, PCUI, Control, and
UART) 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, most new AT commands 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 to the
command.

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. MU609 would return
to SIM failure if SIM card is not inserted. For more information, see Property
Description of related AT in the latest version of MU609 V100R002 of HUAWEI
MU609 HSPA LGA Module AT Command Interface Specification.
Example:
AT+CREG?
+CME ERROR: SIM failure
NOTE
SIM failure indicates 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
AT Command
Timeout Duration
General AT commands
30s
AT+CMSS/AT+CMGS (used to send text
messages)
60s
AT+COPS=? (used to search for networks)
120s
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.
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.

4.2 Establishing Data Connections
Reference process 1:
Command
Description
ATD*99#
*99# is the dial string. This command is usually used
in Windows and only used in the modem port. The
UE switches from command mode to data mode.
After the TE starts the PPP negotiation process, the
UE automatically performs the actions (including PS
domain attaching and PDP activation) required for
establishing data connections.
CONNECT xxx
CONNECT indicates that the data service dial-up
command is being processed by the module. xxx
indicates the data rate, which depends on the
network standard and capability level.
Reference process 2:
Command
Description
AT+CGDATA="PPP",1
This command is equivalent to ATD*99#. This
command is usually used in the Android Radio
Interface Layer (RIL).
CONNECT
NOTE
- Using the previously configured profile, the PPP negotiation between the TE and the UE,
and the PDP negotiation between the UE and the network, the TE obtains the IP and DNS
addresses to establish the routing between the TE and the network.
- When establishing data service connections, the TE must start the PPP negotiation after
the UE enters data mode. Otherwise the UE will only enter data mode but will not establish
data connections with the network.
- The data mode means: After entering data mode, the UE only transfers data packets
between the UE and the network, and will not respond to any AT commands except that
comes from the PCUI port.

4.4 Switch Between Data Mode and Command Mode
4.4.1 Reference Process
Command
Description
ATD*99#
UE dials up.
CONNECT
+++
Enter +++ (three plus signs) to switch the data
service port from data mode to command mode.
The UE can then respond to AT commands and
perform corresponding actions.
ATO
Switch the data service port back to data mode so
that the UE can continue to transmit data.
CONNECT
NOTE
- If there are no data links available, the module will not switch back to data mode but
remains in command mode.
- If the data link is connected, when the module switches from data mode to command mode,
data transmission will be suspended.
- If the data link is connected, when the module switches from command mode to data mode,
data transmission will be resumed.
- Switching between data mode and command mode applies to UART and Modem ports.

ATH
Before this command is executed, the
+++ sequence must be sent to the data
service port. This command is used to
disconnect data service connections.
This command is usually used in
Windows.
OK
Process 2:
Command
Description
AT+CGACT=0
In Android RIL, after a PPP connection
is disconnected, this command is
executed to deactivate the PDP context
to release the data link and disconnect
the data services. The use of this
command is the same as that of ATH.
OK
1. Terminating a data service connection from the TE: the TE sends a PPP
Terminate packet to the UE to pull down the DTR signal. The UE disconnects
the PPP connection, releases the wireless link resource, pulls down the CD
signal, and returns NO CARRIER. As a result, the data service connection is
disconnected. This method of disconnecting data service connections is usually
implemented by the disconnection function of the TE's application.
2. Terminating a data service connection from the UE: The TE sends an AT
command to the UE to pull down the DTR signal. After receiving the AT
command, the UE releases the connection to the network, pulls down the CD
signal, and returns NO CARRIER. As a result, the data service connection is
disconnected. This mode of disconnecting data service connections requires
an AT command interaction tool.
3. When disconnecting data service connections in Android RIL, the module must
kill pppd to disconnect PPP connections before using AT+CGACT=0 to
deactivate PDP contexts and release wireless link resources.

NOTE
- The transparent transmission mode of the internal protocol stack supports UART only.
- The internal protocol stack allows only one link to enter transparent transmission mode. In
addition, before entering transparent transmission mode, ensure that only one link exists at
the current physical port. If the module functions as a server, the link can enter transparent
transmission mode only when the link is requested by a remote client and accepted by the
server.
- The settings (including the time- and length-based transmission mode and 7E detection

6.5 Segmenting and Reassembling Long Text Messages
6.5.1 Segmenting
In PDU mode, text messages can be encoded using GSM 7-bit, 8-bit or UCS2. The
GSM 7-bit encoding scheme is used to encode common ASCII characters,
compressing every 8 characters into 7 characters. The 8-bit encoding scheme is
usually used to encode data such as pictures and ringtones. The UCS2 encoding
scheme is used to encode Unicode characters. According to the existing 3GPP
protocols, the size of the user data contained a PDU is 140 bytes. Therefore, the
maximum number of characters contained in a single message is 160, 140 and 70 for
the GSM 7-bit, 8-bit, and UCS2 encoding schemes respectively. If the number of
characters contained in a text message exceeds the maximum number, the message
will be segmented into several messages. An English letter, a Chinese character, or a
byte of data is considered as a character.
According to the existing 3GPP protocols, after a long text message is segmented,
the number of characters that each message segment can contain is as follows:
- GSM 7-bit encoding: 153 characters
- 8-bit encoding: 134 characters
- UCS2 encoding: 67 characters
The number of available characters per segment is lower, because each segment
must contain segmentation information.
The storage space occupied by a character is as follows:
- GSM 7-bit encoding: 7 bits
- 8-bit encoding: 8 bits
- UCS2 encoding: 16 bits
The storage space occupied by a segment of a long text message is as follows:
- GSM 7-bit encoding: 153 bits x 7 = 1071 bits

Text Message Application Scenarios

49
- 8-bit encoding: 134 bits x 8 = 1072 bits
- UCS2 encoding: 67 bits x 16 = 1072 bits
For all the three encoding schemes, a short message occupies a maximum of 1120
bits (160 x 7, 140 x 8, or 70 x 16) in the storage. If a text message's size is larger
than 1120 bits, the message is a long message.
Figure 6-1 Relationships between character sets
6.5.2 Reassembling
The host applications can reassemble the segments of a long text based on the
following:
- The protocol header in the user data (TP-UD) of a PDU (see the 3GPP TS
23.040 9.2.3.24.1)
- The sender's number contained in each segment
- The interval between the time when each segment is received (The interval
between the two neighboring segments' receiving time is less than 60
seconds, and the maximum interval between the first and the last segments'
receiving time is 24 hours)

9 Sleeping and Waking Up Application
Scenarios
As an embedded component in the host, the module also consumes power, which
increases the power consumption of the integrated product. Therefore, the most
important task of power management is to reduce the power consumption of the
integrated product by enabling the module's sleep mode when necessary.
The host and the module need to wake each other up from sleep if communication is
required. Therefore, another task of power management is to provide a wake-up
control mechanism for the host and module.
Power management involves three parts: the host system software (including the
USB driver/UART driver/GPIO driver/sleep mechanism functions), connection
hardware between the host and module, and the module's software wake-up
mechanism.
This chapter is mainly concerned with the module's software wakeup mechanism,
including the wake-up principle, how USB related events impact on the waking up of
the module and remotely waking up the module, and how the module remotely wakes
up the host.
This chapter briefly describes the power management related connection hardware
between the host and module.
This chapter does not describe the host system software. For example, if the host
runs on a Windows or Mac system, Huawei will provide a USB driver program
corresponding to the module. If the host runs on an Android system, Huawei will
provide Guide to Kernel Driver Integration in Linux for Huawei Modules for users to
configure the USB-based wakeup function of the module.
This document describes typical module application scenarios. A host can be
designed based on the actual system features and the application scenarios of the
module to reduce power consumption of both the module and integrated product.
After the host is designed as recommended by this document, the module's power
consumption and the whole unit's power consumption can meet the performance
requirements. For details, see related description in the product manual.

9.1 Hardware Interfaces
The module communicates with the host using mainly USB or UART. For details
about pins related to power management, see Table 9-1 ..

WAKEUP_OUT
Output
When a wake-up source (see section
9.3.5 ) arrives, these pins output a
low-level-voltage pulse lasting for 1s
during which if other wake-up sources
arrive, the module will ignore the later
wake-up requests. In other words, the
module will not output a second pulse
during this 1s.

When the pin carries a high-level
voltage, the states of the module are
as follows:
The module will be prohibited to enter
sleep mode if the module is awake.
The module will be woken up if the
module is in sleep mode.
When the pin carries a low-level
voltage, the module is allowed to enter
sleep mode. (By default, the pin is set
to INPUT/PD, which is, the software
detects a low-level voltage on the pin
when the pin is not connected.)

Indicates the state of the module.
When the pin carries a high-level

9.3 Software Interfaces
9.3.1 Principle
The module runs on a multi-task software system. The sleep task is granted with the
lowest priority and assigned to detect whether the module can enter sleep mode.
Other tasks (such as the RF, SIM card, USB, and UART) have voting rights. They
vote to decide whether the module can enter sleep mode. When no other tasks are
running, the sleep task is executed. If the sleep task detects that all other tasks agree
on the module's sleep, the module enters sleep mode, as shown in Figure 9-4 . At
this time, the baseband chip reduces the work frequency, and the RF enters the
Discontinuous Reception (DRX) mode.

NOTE
The module's sleep mode is different from working mode or flight mode set using the
AT+CFUN command. The RF will be turned off when the module enters LPM mode using the
command AT+CFUN=0 while the RF will enter DRX mode without being turned off when the
module is in sleep mode. For more details, refer to the latest version of MU609 V100R002 in
HUAWEI MU609 HSPA LGA Module AT Command Interface Specification.
The module enters sleep mode automatically when the sleep task detects that all
other tasks agree on the module's sleep. The sleep period of the module depends on
the current working state and circumstance. The period may last for several seconds,
or up to several minutes.

9.3.2 USB and Sleep
USB is an important communication channel between the module and the host.
According to the USB protocol, normally a hub or a root hub periodically sends Start
of Frame (SOF) data packages (one data package per ms using full-speed USB and
one package per 125 µs using high-speed USB). Through this mechanism, USB
always votes to stop the module from entering sleep mode.
When the USB driver provided by Huawei detects that the module and the host have
not exchanged data in 5 seconds, the USB driver will enable the port's suspend
feature, stopping SOF data packages being sent and suspending the USB controller.
This enables the USB to vote to agree the module's sleep.
NOTE
If the USB driver used is developed by users or is integrated with external application, ensure
that the USB driver supports the USB suspend features (including selective suspend and
global suspend, as defined in the USB standard) .
9.3.3 UART and Sleep
UART is an important communication channel between the module and the host. If
the host uses UART (a TTL level Interface), it can connect to the module's UART
directly. If the host uses RS232, it can connect to the module's UART through a
conversion chip such as MAX232.
NOTE
Regardless of the connection modes, when there is no data transmitted on the UART, the host
should set the RX pin of the module's UART to low level so that the module can enter sleep
mode.
9.3.4 Module Wake-up
RF periodically wakes up the module based on the DRX cycle (depending on the
actual configuration of the network system), as shown in Figure 9-4 .
Other aperiodic events include:
1. The host sends data using USB/UART or pulls WAKEUP_IN up.
2. Changes on the network, for example, an incoming text message, a signal
change, a network working mode change, a network search, an IP data package
(when a dial-up network connection is set up).
3. Software system events such as a timer
4. Abnormal events, for example, an antenna drops or a SIM card becomes loose.
9.3.5 Host Woken up by Module
Wake-up Source
A wake-up source is a module event that can wake up the host, for example, a text
message, data (PPP data, TCP/UDP data from the network), and unsolicited
messages.

Remotely Waking up the Host Using USB
When the host is in sleep mode and the USB controller is in suspended mode, if the
module needs to send data to the host (for example, a wake-up source has arrived),
the module sends a remote wake-up signal that lasts 3 ms to inform the host to start
USB resume (as shown in Figure 9-6 ). To complete the procedure, the following
conditions must be met:
1. The USB controller on the host supports USB remote wake-up and can wake up
the host.
2. The USB driver enables or disables remote wake-up by executing
SET_FEATURE and CLEAR_FEATURE commands. Therefore, remote wake-up
must be enabled on the USB driver before USB enters suspended mode.
3. When the host receives the remote wake-up signal from the module, the host
needs to send a full speed K signal that lasts at least 20 ms. When the USB
controller resumes, the host must send the SOF token within 3 ms from the
startup of the idle state. Otherwise, the module enters suspended mode again,
as shown in Figure 9-6 .

Figure 9-7 Successful procedure of remote wake-up
WAKEUP_OUT Waking up the Host
The module will output a 1s pulse using WAKEUP_OUT/WAKE# as shown in Figure
9-1 when a wake-up source arrives. The host wakes itself up after detecting the level
change.
Remote Wake-up Configuration
The power consumption of the host increases if it is frequently woken up. The host
can configure the module's wake-up sources using AT^WAKEUPCFG and
AT^CURC command so as to reduce the power consumption.
The AT^WAKEUPCFG command can be used to choose wake-up sources and the
wake-up channel (USB or WAKEUP_OUT). The AT^CURC command can choose
unsolicited messages. For more details, refer to AT Command Interface Specification.

Configuration operations (initialization and serial port configuration), phonebook
operations, and PIN operations can be performed when the module is not in sleep
mode; no matter the module is idle or processing services, because no interaction
between the module and the network is required.
Especially, if the module is processing internal/external protocol stack services,
operations such as configuration, phonebook and PIN operations must be performed
at ports that are not used to provide data services.

Requirement of the AP
The AP is required to have 4KB RAM at least (used to store the cache data). If AP
only needs to support the increment upgrade, AP FLASH memory must be larger
than 1 MB. If AP needs to support the full upgrade, or both the increment upgrade
and the full upgrade, AP FLASH memory must be larger than 22 MB. (The full size of
MU609 firmware upgrade files is 22 MB.)
1. AP should be able to access and load the upgrade files.
2. AP should have a file transmission tool, this tool need to support 1K-Xmodem
protocol.
Finding the PCUI port on Android and Linux System
Step 1 Enter /sys/bus/usb/drivers/option, and look out the following types of folders.
Step 2 Enter these folders, and view the bInterfaceProtocol value.
If the bInterfaceProtocol value is 02, the port is PCUI.

After the module reports 'C', the host transmits the upgrade package to the module using the
xmodem or 1k_xmodem protocol.
Interfaces supported by the module:
Full upgrade: serial ports and PCUI port (baud rate: 115200 bit/s)
Increment upgrade: serial ports and modem ports (baud rate: current baud rate of the module)
The full upgrade takes up much time, so the increment upgrade is recommended.
17.1.4 Troubleshooting
If using the full upgrade by the PCUI port, after the module is restarted, the PCUI port
number may be changed. So you need to find the corresponding port, and then send
the local upgrade package.

18.3 Exception Handling
In the industrial product design, in order to ensure reliable operation of the device for
a long time, the host need take into account fault-tolerant design. This is because
that the operation of the terminal environment is very complex and not easy to design
the system architecture for complete simulation. Since the environment maybe
change, and the various hardware components within the device are not always
guaranteed to work at the expected condition, even if the module is able to maintain
the electrical specifications claimed to work, but the external signal may also lead to
abnormal changes in the module beyond the normal working condition. For example,
the power supply voltage drop may cause the module reboots, so we recommend in
the system design customers should consider the types of abnormal events, and add
a corresponding recovery process, so that the module can be restored after a brief
interruption to the normal communication.
18.3.1 Module Reset
- Exception Description
In some extreme condition (for example, the power voltage is not stable), the module may
be reset.
- How to Detect the Exception by the Host
The module will report "^SYSSTART" to the host.
- Host Resume Steps
After the module reset, the host need reconfigure the configuration, and reconnect
the data service, if the module was connected to network before resetting. If the
module is connected to network by embedded protocol IP stack or external protocol
stack, the host need reconnect too.
- Host Resume Example
For the data service reconnected by external protocol stack, please take the following
two steps.
Step 1 Input AT+CGDCONT=1,"IP","1234"
Step 2 Input ATD*99#
For detail, please refer to Chapter 4 External Protocol Stack Application Scenarios.
18.3.2 Module Going to Dump Status
- Exception Description
In some extreme condition, the module may go to dump status to protect itself. In this
status, it cannot response to any ATcommand, and its USB port status is not the same as
normal status.
- How to Detect the Exception by the Host
Any AT command input will have no response, and the module only has two USB ports.
- Host Resume Steps

If the module goes to dump status, please make sure the power voltage are
recommended in Hardware Guide of the module. And then power off the UE for
several minutes, then power on it again.
18.3.3 Module Data Service Disconnected
- Exception Description
In some extreme condition, the data service may be disconnected automatically. The
reason maybe the network signal is not good, or the network is busy, or it is disconnected
by the network.
- How to Detect the Exception by the Host
Query the current PDP Activation state:
Run:
AT+CGACT?
Response:
+CGACT: 1,0
OK
For details, please refer to the latest version of MU609 V100R002 of HUAWEI
MU609 HSPA LGA Module AT Command Interface Specification.
- Host Resume Steps
In this condition, the host need reconnect the network.
- Host Resume Example
For data service reconnected by internal protocol stack
Step 1
Run:
AT^IPINIT="1234"
Response:
OK
Step 2
Run:
AT^IPOPEN=1,"TCP","172.22.44.33",5000,5500
Response:
OK
For details, please refer to Chapter 5 Internal Protocol Stack Application Scenarios.
18.3.4 User Configuration Lost
- Exception Description
In some extreme condition, the user configuration maybe loses after reset for several
times.

The AT command "AT+IPR?" will return the baud rate, but the baud is not what the
host set or have no response by the UART.
The AT command "AT+CGDCONT?" will return the pdp profile, but the pdp profile will
be empty or not the same as that the host set.
- Host Resume Steps
In this condition, the host need reconfigure the setting. We suggest the host configure
the setting after powering on the module.
- Host Resume Example
Try to connect the module with the baud rates the module supports, and change the
baud rate that the host needs.
Run:
AT+IPR=115200
Response:
OK
