Question

How to change USB composition mode to Mobile Broadband Interface (MBIM) that is used by Windows 8 and 10 systems for data connectivity and enabling support for the built-in connection manager in Windows?

Solution

This is done by sending AT commands to the Modem or AT serial interfaces that are accepting AT commands and changing the USB endpoint composition:

Sierra Wireless EM74xx, MC74xx series module:
AT!ENTERCND=”A710”
AT!USBCOMP=1,1,100D
AT!RESET

Sierra Wireless EM73xx, MC73xx series module:
AT!ENTERCND=”A710”
AT!UDUSBCOMP=8
AT!RESET

Simcom SIM7xxx series modules:
AT+CUSBPIDSWITCH=9003,1,1
AT+CRESET

ZTE Welink ME3630 series:
AT+ZSWITCH=8
AT+ZRST

Telit LM940:
AT#USBCFG=2
AT#REBOOT

Telit LE910x V2:
AT#USBCFG=3
AT#REBOOT

On Huawei modules the USB mode changing is done automatically by the Windows drivers and otherwise defaults to the modules standard endpoint interfaces.

Question

How do we use the GPS functionality of the Sierra Wireless EM/MC7455 modules?

Solution

The Sierra Wireless EM/MC74 series modules include a GNSS tracker that can be enabled to acquire location data.

Details of the available AT commands related to GNSS functionality are described in the AT commands reference manuals chapter 7: GNSS Commands.

A basic GNSS tracking session outputting the location data on the NMEA virtual serial interface can be started with the following AT command
AT!GPSTRACK=fixType,maxTime,maxDist,fixCount,fixRate

Bellow command starts a standalone tracking with 255 seconds timeout value, 50 meter accuracy, continuous fixing, fixed data output rate every second on the NMEA virtual serial interface:
AT!GPSTRACK=1,255,50,1000,1

Depending on if an GNSS antenna with or without low noise amplifier (active/passive antenna) are used, the AT+WANT command can adjust if the antenna power supply of 3 volt should be enabled or disabled. Configure GNSS port for a passive GPS antenna:
AT+WANT=0

A GNSS tracking session can be interrupted and ended with the command:
AT!GPSEND

In Linux applications it is recommended to use the Sierra Wireless provided GobiNet and GobiSerial drivers for optimal performance. If the Linux in-kernel drivers are used, it might be needed also to send the bellow sentence to the ttyUSBx that represents the NMEA serial interface in order to activate the data stream on the interface:
$GPS_START


The antenna connector used by the GPS tracker can be either through the dedicated GNSS port or it can be combined with the Rx Diversity antenna located on the AUX marked connector. This is selected by changing a parameter with the AT!CUSTOM command:

To select usage of the dedicated GNSS antenna connector on cellular module, execute:
AT!ENTERCND="A710"
AT!CUSTOM="GPSSEL",0
This will select usage of the dedicated GPS antenna slot (Default value)

For further details on how to configure the GPS for different application and scenarios, such as using Assisted GPS, or changing output formats etc. please relate to the AT commands reference.

Question

Why should we use USB3 instead of USB2 as host system data interface if the cellular module can support both?

Solution

Cellular modules supporting higher data throughput rates like LTE Advanced, category 6 and above (300Mbps downlink and 50Mbps uplink) often support both USB3 interface as well as USB2 interface towards the host system.

It is recommended to implement and use the USB3 data interface rather than the older USB2 interface on these modules between host system and the cellular module. This because USB3 can support around 10 times higher data throughput rate compared to USB2 and avoid a possible bottleneck / limitation in the data interface between host and cellular module.

If a miniPCIe based cellular module implementing USB3 are used, please verify that conflicts don't occur towards your hosts miniPCIe socket, as the USB3 interface is not implemented by default in the miniPCIe standard and therefore signal collisions can happen between USB3 pins and PCIe data interface pins situated on same locations. Refer to the cellular module hardware guides and host system hardware guides to verify this.

Question

How to collect initial diagnostics data for Sierra Wireless EM/MC74 series cellular modules when requesting technical support?

Solution

In order to troubleshoot and solve a technical problem, we ask you to please provide information about your system and logs from the related module when creating a technical support ticket.

Please provide a problem description of what exact problem is and in what precise situations it is present.

Describe the host system:
-Hardware (system board, peripherals...)
-Operating system and detailed versions (E.g. Windows, Linux dist, release, kernel...)
-Drivers and driver versions

Identify the precise details of cellular module found on label:
-Model
-SKU/BOM or P/N code
(For RMA returns the IMEI number is required also)

The logs from module firmware can be acquired by accessing one of the USB enumerated serial (COM) interfaces accepting AT commands. (In Windows this is generally modem devices or AT commands serial interfaces). Send the following AT commands to module and capture the text output and include them when creating the the technical support ticket.

Question

How can we establish data connection for cellular modules in Windows 8 and Windows 10 systems?

Solution

Microsoft Windows desktop versions starting from Windows 8 and newer have built in data connection manager for WWAN, Wifi etc. that can be used to configure, control and establish the data connection of cellular module that support MBIM interface, which most cellular modules do.

The connection managers settings and controls can be found and accessed on Windows desktop start menu through the network icon (see picture).

The Cellular tab can be found in Windows system settings and if needed the connection APN details can be manually entered through "Advanced options".

Question

Windows system show multiple network devices for my Sierra Wireless MC74-, EM74-series cellular module

Solution

Sending the following AT Commands to the modules MODEM Serial COM port interface will change the USB profile for exposed interfaces towards host system.

Setting for DIAG, NMEA, MODEM, RMNET0 interface: (Linux - QMI with one network interface)
1. AT!ENTERCND=”A710”
2. AT!USBCOMP=1,1,10D
3. AT!RESET

Setting for DIAG, NMEA, MODEM, RMNET0, RMNET1 interface: (Linux - QMI with two network interfaces)
1. AT!ENTERCND=”A710”
2. AT!USBCOMP=1,1,50D
3. AT!RESET

Setting for DIAG, NMEA, MODEM, MBIM interface: (Enabling MBIM mode supported by Windows 8 & 10)
1. AT!ENTERCND=”A710”
2. AT!USBCOMP=1,1,100D
3. AT!RESET

Beware to not disable the MODEM serial interface, leaving module inaccessible for AT commands.

Question

How can we capture DM serial port logs for Sierra Wireless EM/MC series cellular modules in Linux?

Solution

In the Sierra Wireless QMI SDK downloadable archive there is a a DM log tool in the tools folder.
Run the dmcapture.sh script with desired filter, and the ttyUSB0 (DM port) device selected.

E.g. like this:
sudo ./dmcapture.sh -l -d /dev/ttyUSB0 -o testlog -f ./filters/v11026_Generic_GSM_WCDMA_LTE_IP.sqf

This will create a log file that can be sent for analyze and debug to Sierra Wireless.

Question

How can I enable DC voltage output for active GPS/GNSS antennas on modules that support this feature?

Solution

This is enabled by the following AT commands:

For Sierra Wireless EM/MC74 series (Output: 3.15V):
AT!ENTERCND="A710"
AT+WANT=1

For Sierra Wireless MC73 series (Output: 3.15V):
AT!ENTERCND="A710"
AT+WANTGNSSPWR=1

For Simcom (Max output 61*50mV = 3.05V):
AT+CVAUXS=1
AT+CVAUXV=61

Question

Sierra Wireless MC74-series module is not detected by the operating system?

Solution

Not all miniPCIe interfaces can support USB3 according to the pin configuration Sierra Wireless have chosen.
USB3 support is not defined in mPCIe standard by default and therefore conflicts can occur with some system boards even if the MC74xx module will in most cases switch to USB 2.0 HS if USB3 isn't supported correctly.

The only currently working solution to this is to isolate USB3 data pins #23, 25, 31, 33 on top side of the card so no connection to miniPCIe socket are achieved for them. This could be done in board design or with proper adapter or e.g. by adhesive tape for further testing/troubleshooting. The pins #27, 29 in between the others serve as two out of several grounding pins and can also be isolated for easier application when troubleshooting.
