MX6 boards, and in the past, have mostly just shrugged. The steps are also different for Android, embedded Linux and desktop distributions. As you can see in this patchwe did have to add some USB device ids and make minor updates to the kernel as provided by the vendor.
In the process, we should now also support the following Huawei models for various regions and carriers:. These images contain Freescale-licensed content, so you will need to register on our web-site and log in before you can accept the license agreement and download the images from here:. If not, there were some notes in our first release that describe a more complicated way of programming eMMC.
Then insert your SIM card to the socket in the bottom side of the board as shown in the figure below. Nitrogen-Max board, bottom, SIM card inserted to the socket. We will solve the modem handling tasks with the modemmanager package. ModemManager is a daemon that gets started at boot time. The modemmanager package provides a command line tool, named mmclito control the ModemManager daemon.
That will be the tool used below. We will solve the connection handling tasks with the network-manager package. With the NetworkManager we can create connection configuration files, with specific parameters, that makes internet connection handling very easy. We back-ported modemmanager 1. If everything went well, your ModemManager and NetworkManager will start at boot time. You can check it like so:. When ModemManager starts it scans the serial ports for modems and it tries to recognize them.
It takes quite long, seconds!!! And we start screen serial console to communicate with modem on ttyUSB2 primary port of the modem, as shown above.
The dark mode beta is finally here.

I am trying to configure a modem connection using mmcli and nmcli but I keep getting pppd Modem Hangup and I don't know what else to check. APN and SIM PIN number are correct as the connection is established sometimes but it fails many times to reconnect and it's far from a robust connection.
I triple checked them and the connection works fine on a different router with a different modem. I see those logs quite often in the journal. Sometimes pppd works but quite rarely. I need to do a few reboots, power cycles and eventually it connects but I would like a robust solution that reconnects the modem properly. If you have any clue what might be wrong or what else to configure please let me know : Many thanks! Learn more. Asked 5 months ago.

The following figure explains the 4G LTE packet core network architecture. The PGW performs policy enforcement, packet filtering for each user, charging support, lawful interception, and packet screening.
The RNC carries out radio resource management and some of the mobility management functions and is the point where encryption is done before user data is sent to and from the mobile. Active GPS antenna is supported only in the standalone mode. An Active GPS antenna includes a built-in Low-Noise Amplifier that provides sufficient gain to overcome coaxial cable losses while providing the proper signal level to the GPS receiver. If the application supports serial port, run a serial port emulation program to create a virtual serial port over the LAN or WAN connection.
This support includes the ability to view up to 25 received texts, and archive more messages in a custom file location. SMS is supported on multiple carriers.
The receiving device uses the same process to return a reply to the sending device. The following figure describes the flow from a mobile device to a sending device. For SMS transmission to work, end users must have a text-capable device, and optionally, a text plan.
If end users do not have a text plan, standard SMS rates apply to their text transmissions. The SMS-initiated Data Callback feature allows customers to set up a data connection by sending a text message to the Cisco 4G LTE router and includes the message screening functionality using the originating number to improve feature security and eliminate unauthorized callback requests.
Contact your service provider for the PIN code. The configuration is associated with the cellular controller that is specific to a router EHWIC slot number.Some carriers require you to enter your APN settings to set up your cellular service. If you can't modify your APN settings, contact your carrier. Don't edit the APN unless directed by your carrier or mobile device administrator.
Contact your carrier to verify the correct APN settings. If your device doesn't have either option, contact your carrier. To change your settings, tap each field and enter the details from your carrier. The settings should save automatically. If your carrier needs a different APN setting, you might be able to use a configuration profile with the correct setting. Unless you're using a configuration profile, updating iOS resets any changes made to your APN settings.
You might need to reenter your settings after an iOS update. If you installed a configuration profile, the profile's default information will be used instead. Change cellular settings with mobile device management. On iPad: Remove the configuration profile and add it again. Learn more Change cellular settings with mobile device management. Yes No. Character limit: Maximum character limit is Ask other users about this article Ask other users about this article.Thanks to the built-in plugin architecture, ModemManager talks to very different kinds of modems with very different kinds of ports.
These are used for defining the device an option operates on. These are useful for getting connected or disconnected and understanding the state of things as fast as possible without worrying so much about the details.
See also --help-sms which is related. See also --help-messaging which is related. In most cases ERR for displaying errors are the important messages.
The default mode is ERR. This is only useful when expecting pure RS modems, as they are not notified automatically by the kernel.
The UID that should be given is the value of the Device property exposed by a given modem i. This command will not exit right away, as that would implicitly remove the inhibition.
When a device is inhibited via this method, ModemManager will disable the modem therefore stopping any ongoing connection and will no longer use it until it is uninhibited. The supported KEY s are: 'action' Action to report, one of 'add' or 'remove'. All ports reported with the same 'UID' value will be considered part of the same device, which may be useful for e. This command will not exit right away.
If no action is provided, the default information about the modem, bearer, etc. They can be found using mmcli -L. The Modem is replaced with the object name in use, like Bearer. Some operations require a MODE.
MODE can be any combination of the modes actually supported by the modem. In the perfect case, the following are possible: '2G' - 2G technologies, e. This powers the antenna, starts the automatic registration process and in general prepares the modem to be connected. This disconnects the existing connection s for the modem and puts it into a low power mode. The CODE provided is vendor specific.

Without the correct vendor code, it's unlikely this operation will succeed.It can be utilized as a replacement for nm-applet or other graphical clients. See nmcli-examples 7 for ready to run nmcli examples. Scripts: Utilize NetworkManager via nmcli instead of managing network connections manually. Note that NetworkManager can also execute scripts, called "dispatcher scripts", in response to network events.
See NetworkManager 8 for details about these dispatcher scripts. Servers, headless machines, and terminals: nmcli can be used to control NetworkManager without a GUI, including creating, editing, starting and stopping network connections and viewing network status.
When using this option nmcli will stop and ask for any missing required arguments, so do not use this option for non-interactive purposes like scripts.
This option controls, for example, whether you will be prompted for a password if it is required for connecting to a network. This option controls color output using terminal escape sequences. The default value is auto. The actual colors used are configured as described in terminal-colors. Please refer to the Colors section for a list of color names supported by nmcli.
Explicitly enabling coloring overrides the environment variable. Instead of conducting the desired action, nmcli will list possible completions for the last argument. This is useful to implement argument completion in shell. The exit status will indicate success or return a code 65 to indicate the last argument is a file name.
This option is used to specify what fields column names should be printed. Valid field names differ for specific commands. List available fields by providing an invalid value to the --fields option.
This option is used to print values from specific fields. It is basically a shortcut for --mode tabular --terse --fields and is a convenient way to retrieve values for particular fields. The values are printed one per line without headers.
If a section is specified instead of a field, the section name will be printed followed by colon separated values of the fields belonging to that section, all on the same line. Output is a table where each line describes a single entry. Columns define particular properties of the entry. Each entry comprises multiple lines, each property on its own line. The values are prefixed with the property name. If omitted, default is tabular for most commands.
For the commands producing more structured information, that cannot be displayed on a single line, default is multiline. Currently, they are:. Output is pretty. This causes nmcli to produce easily readable outputs for humans, i. When using this option nmcli will display passwords and secrets that might be present in an output of an operation. This option also influences echoing passwords typed by user as an input.The settings are provided by the cellular network service provider Carrier.
Although APN settings are provided by Carriers if you face problems while using your internet you will have to set it manually. In this situation, you will have to have the knowledge of the APN settings. Although most APN settings are almost same in all the fields their corresponding values differ in several fields. Here is a list of APN settings for all carriers. Read also- Android 8. Before we can proceed with the APN settings for all carriers here is how you can go ahead with the manual settings to set APN for any of the network providers mentioned below:.
Now that you have the list of APN settings it would be both informative and important that you knew what these terminologies in the list of APN settings mean. A cellular network provider ascertains the different settings from their end. Proxy — Proxy is an optional field and states the HTTP proxy address, usually the field is left blank. Username and Password — Username and Password is an optional field but at times it is used to validate the point-to-point connection between the mobile network provider and the phone that is using its network.
They are compulsory fields and every country has their own distinct code. The MNC also differs from region to region in the same country. Using the above you can manually set the APN settings.
