I have a dlink DW-157 3g dongle. I am trying to assign the same port to the dongle everytime it boots up by modifying the udev rules file. Since the dongle on boot boots up as a storage media, I have to enter the command below to eject and mount for modem mode and then other command below it to make use of the ttyUSB ports of the modem for running a dial up modem. sudo eject /dev/sr0 sudo /bin/sh -c "echo 2001 7d0e > /sys/bus/usb-serial/drivers/option1/new_id After entering these, sudo dmesg| grep ttyUSB appears as: [ 17.581264] usb 1-1.4: GSM modem (1-port) converter now attached to ttyUSB1 [ 17.584470] usb 1-1.4: GSM modem (1-port) converter now attached to ttyUSB2 [ 17.593854] usb 1-1.4: GSM modem (1-port) converter now attached to ttyUSB3 [ 17.594869] usb 1-1.4: GSM modem (1-port) converter now attached to ttyUSB4 The actual port on which I can use the modem for dial up is ttyUSB1. So, I'm trying to assign ttyUSB1 to d_uart in my udev rules file: ACTION=="add", ATTRS{idVendor}=="2001", ATTRS{idProduct}=="7d0e", SYMLINK+="d_uart" But what happens is d_uart gets assigned to ttyUSB4. What do I do to assign it to the first port always (ttyUSB1 in this case) ? Also, the output of the command for ttyUSB1,ttyUSB2,ttyUSB3 and ttyUSB4 for the comnand below: udevadm info -a -n /dev/ttyUSB4 | grep '{serial}' | head -n1 is the same.

I have a Debian OS on a Banana pi and I use a Huawei 3G modem to connect to the internet from it using the wvdial tool. I also have the usb-modeswitch installed and I think the modem is working as a modem correctly. The existing setup was working correctly for a few months until I decided to turn off the banana pi and left it for about 3 months and now when I try to connect to the internet using the same settings it is not working. I am able to connect to the internet carrier but cant use the internet. When I type **ping 8.8.8.8** or **ping -I ppp0 8.8.8.8** it does not respond anything and returns: --- 8.8.8.8 ping statistics --- 194 packets transmitted, 0 received, 100% packet loss, time 193000ms my **wvdial.conf** looks like this: [Dialer Defaults] Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 Init3 = AT+CGDCONT=1,"IP","internet.unite.md" Modem Type = Analog Modem Studpi Mode = 1 Baud = 9600 New PPPD = yes Modem = /dev/ttyUSB0 ISDN = 0 Phone = *99# Username = tmn Password = tmn when I run **sudo wvdial** I get: --> WvDial: Internet dialer version 1.61 --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 OK --> Sending: AT+CGDCONT=1,"IP","internet.unite.md" AT+CGDCONT=1,"IP","internet.unite.md" OK --> Modem initialized. --> Sending: ATDT*99# --> Waiting for carrier.

I have a ZTE MF190 USB stick on a Raspberry Pi. I run it with wvdial and it works fine. I want to log the signal strength. The appropriate AT command is AT +ZRSSI. When I insert this into wvdial.conf as part of the modem init strings and run wvdial at the terminal I get to see the output. I want to know the signal strength at a remote unit. I would like to be able to echo or redirect the init dialog to a file ......

I'm trying to get wvdial to work automatically with a Telit LE910 WCDMA modem. My script will start up the connection as needed, then disconnect when not needed to prevent wasted data. One of the telit commands to set up the modem is to send AT+CGPADDR=3 and the result from this returns the IP address my carrier has provided. in my wvdial.conf, I have this as one of the lines init5 = AT+CGPADDR=3 The response to that init string is +CGPADDR: 3,"100.121.106.244","254.128.0.0.0.0.0.0.0.0.1.128.162.96.1" OK The IP address changes every time I connect. With all the appropriate configurations in my wvdial.conf, wvdial completes successfully and connects. But my connection isn't fully complete until I manually issue two more commands in script or via command-line, and I'm not finding an easy way to pass that ip address back to the script to run unattended. To complete the connection, I have to type ifconfig usb0 100.121.106.244 netmask 255.255.255.0 -arp up route add default usb0 Is there some way in the wvdial.conf to have it do something with the init5 variable that could pass the result back to the script so that the connection completes automatically? The rest of my wvdial is [Dialer Defaults] Init1 = ATZ Init2 = AT+CGMR Init3 = AT#ncm=1,3 Init4 = AT+cgact=1,3 Init5 = AT+cgpaddr=3 Init6 = at+cgdcont?

I have configured my network to get internet from HUAWEI E3131 usb modem at start. So I have prepared special wvdial.conf and interfaces files: **wvdial.conf:** root@debian:/home/s# cat /etc/wvdial.conf [Dialer Defaults] Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 Modem Type = Analog Modem Baud = 9600 New PPPD = yes Modem = /dev/ttyUSB0 ISDN = 0 [Dialer orange] Phone = *99# Username =; Password =; root@debian:/home/s# **interfaces:** root@debian:/home/s# cat /etc/network/interfaces auto lo iface lo inet loopback auto ppp0 allow-hotplug ppp0 iface ppp0 inet wvdial provider orange root@debian:/home/s# Unfortunately with this configuration the internet connection works only after restarting my debian 8. So when I turn on the pc it doesn't work but when I then restart it, it gets to work. How to make internet start at turning the pc on? It should be wvdial because I share the ppp internet connection. **edit** There is no dual boot, no Windows installation in the system.

I am using a Yocto image based on the linux-mainline kernel. I have systemd on the embedded OS that I have created. ### Aim I have a UMTS dongle connected to the board which will use usb_modeswitch to recognise the dongle and wvdial to connect to the 3G insfrastructure. ### Method I wrote a simple bash script in /usr/umts.sh as follows #!/bin/bash sleep 1; usb_modeswitch --default-vendor 12d1 --default-product 1446 -J sleep 1; /usr/bin/tmux new-session -d -s Cloud /usr/bin/tmux set-option set-remain-on-exit on /usr/bin/tmux new-window -d -n 'wvdial' -t Cloud:1 'sleep 1; /usr/bin/wvdialconf; /usr/bin/wvdial'; usb_modeswitch will configure the USB Dongle and the next part will create a tmux session and trigger wvdial within. my systemd script looks like follows in /etc/systemd/system/enable-umts.service GNU nano 2.2.5 File: /etc/systemd/system/enable-umts.service [Unit] Description=Enable UMTS Dongle for Cloud Connectivity [Service] Type=oneshot ExecStart=/usr/umts.sh [Install] WantedBy=default.target (I have given execution rights to the script using chmod +x /usr/umts.sh) I reloaded the daemon systemctl daemon-reload and enabled the service systemctl enable enable-umts.service and rebooted the board (NOTE: I have only root on board and no other user) The dmesg infact triggers the usb_modeswitch from the script above and I see related messages [ OK ] Started Enable UMTS Dongle for Cloud Connectivity.

If execute the script /usr/umts.sh as a standalone script then in fact it does everything it is supposed to do (open a new tmux session and triggers wvdial) What is wrong here? I tried adding more sleep time but that isn't working either. Sadly there is no rc.local or cron available for the yocto image I am working on.

I have a USB modem detected as a device device file (/dev/ttyACM0). Redirecting AT commands to the device file seems to work as the modem responds. Am going with the following assumption, the upper part represents a control channel. Through it one can dial up, setup the modem, cancel the connection... in general do things related to controlling the modem without actually handling the data. By data I mean everything that aren't controls (for example HTTP packets). **Where does the data flow happen? If it's through the same file, how is that multiplexed?** Also ideally, one would like the modem just to be an underlying "service" that provides a network interface with an IP, so one can abstract that out and use TCP/IP sockets. The sockets are implemented in the kernel. **How does this fit into the picture once the modem is exposed as /dev/ttyACM0 in user space**?

I'm trying to get a Huawei E398 3G USB modem to work on my Raspberry Pi 3 When I run wvdial I get the following response: pi@mypi:~ $ sudo wvdial --> WvDial: Internet dialer version 1.61 --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 ERROR --> Bad init string.

I've tried every other init string I could come across, but every single one gives me the same error.

I'm trying to get work crontab, I'm editing crontab with sudo crontab -e. After that I add the line @reboot wvdial at the end of file, theoretically, every boot the computer connect with wvdial but it doesn't work, why? Where I'm wrong? I'm trying also with @reboot /usr/bin/wvdial but no chance to get this work. How can I set up my crontab file to run wvdial successfully at startup? When capturing the output from wvdial, I see this: --> WvDial: Internet dialer version 1.61 --> Cannot open /dev/ttyUSB1: No such file or directory

Some AT commands in wvdial return their answers with a delay. This period of time depends on the command. For instance, when you want to scan for available networks, you can use the AT+COPS=? command. The scanning process takes about 30s, but wvdial doesn't wait until it's finished and resend the command. After the second try, wvdial gives up with the following error: # wvdial info-scan --> WvDial: Internet dialer version 1.61 --> Initializing modem. --> Sending: AT+COPS=? --> Re-Sending: AT+COPS=? --> Modem not responding. After some time (30s), I can issue another command via wvdial, it can be anything, for instance ATZ+CFUN=1, which does nothing when the modem is already on, but after sending the command, I get the output from the previous one: # wvdial modem-start --> WvDial: Internet dialer version 1.61 --> Initializing modem. --> Sending: ATZ+CFUN=1 +COPS: (2,"T-Mobile.pl","TM PL","26002",2),(1,"T-Mobile.pl","TM PL","26002",7),(3,"Plus","PLUS","26001",7), (3,"Play","Play","26006",7),(3,"Orange","Orange","26003",7), (3,"Play","Play","26006",2),(3,"Orange","Orange","26003",2), (3,"Plus","PLUS","26001",2),,(0,1,2,3,4),(0,1,2) OK So is there a way to set some kind of timeout for the commands so they could get the delayed answer?

I've checked their man pages, but I'm still confused. I just know they are all related to ppp connections. I'm surprised that when I googled "pon wvdial relationship", I get no useful results, so I ask this question here. Who can tell me the role of these three tools? I still feel they do the same thing... and... I find that a new tool - pon.wvdial has come out, and what is it? I'm really confused with these tools...

I have a Huawei cell modem EM680 with which I can establish a connection on my Ubuntu 13.10 box just fine. I plug it in and I can establish a connection using the Connections Manager. I have a box without X server and I want to establish a connection with that same modem on that box. I can get a serial link at /dev/ttyUSB1 and if I connect to it using screen /dev/ttyUSB1 460800 and send AT, it responds with OK just fine — so the modem works! After that I tried to establish a connection using wvdial with my /etc/wvdial.conf configured like this: [Dialer Defaults] Init1 = ATZ Init2 = AT+CFUN=1 Init3 = AT+CGDCONT=1,"IP","m2mstatic.apn" Modem = /dev/ttyUSB1 Phone = *99***1# Modem Type = USB Modem Username = "blank" Password = "blank" Stupid Mode = yes New PPPD = yes Baud = 460800 ISDN = 0 I tried to launch wvdial without any options or with wvdial eap-interval 1 require-chap because in my Connection Manager window, under the tab PPP the following checkboxes are checked: * EAP * MSCHAP * PAP * MSCHAPv2 * CHAP * Use BSD data compression * Use Deflate data compression * Use TCP header compression But upon launch I just get # wvdial eap-interval 1 require-chap --> WvDial: Internet dialer version 1.61 --> Warning: section [Dialer eap-interval] does not exist in wvdial.conf. --> Warning: section [Dialer 1] does not exist in wvdial.conf. --> Warning: section [Dialer require-chap] does not exist in wvdial.conf. --> Cannot get information for serial port. --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: AT+CFUN=1 AT+CFUN=1 OK --> Sending: AT+CGDCONT=1,"IP","m2mstatic.apn" AT+CGDCONT=1,"IP","m2mstatic.apn" OK --> Modem initialized. --> Sending: ATDT*99***1# --> Waiting for carrier.

Exit code 8 in the pppd man page says: The serial port could not be opened. Which is ridiculous as I just opened (and **closed(!)** it with screen). Any ideas where I'm going wrong or what I'm missing? ### Edit I just found the connection manager's config file and it looks like this: [connection] id=Rogers uuid=5c4ed6f8-9ece-4888-a129-65ed5c741502 type=gsm permissions=user:ron:; [gsm] number=*99# password-flags=1 apn=m2mstatic.apn pin-flags=1 [ipv4] method=auto

I'm using pppd and wvdial on my ARM Linux embedded system. I have a CDMA modem connected via a serial port and am connecting to the Verizon network.

Linux is kicking my butt. I have attempted to use wvdial for the first time to get 3G working on my Raspberry Pi, but things have not gone as expected. First of all, when I do a simple sudo wvdialconf The scan gives me the following message: Ok. Probably not the best start I can get because of the errors on lines: ttyUSB0: ATQ0 V1 E1 S0=0 -- ERROR ttyUSB0: ATQ0 V1 E1 &C1 -- ERROR ttyUSB0: ATQ0 V1 E1 &D2 -- ERROR I figured that these errors could probably be the reason of the failure of my later attempt to use wvdial, which gives me the output as such: --> WvDial: Internet dialer version 1.61 --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: ATQ0 V1 E1 +FCLASS=0 ATQ0 V1 E1 +FCLASS=0 OK --> Sending: AT+CGDCONT=1, "IP", "internet" AT+CGDCONT=1, "IP", "internet" ERROR --> Bad init string. --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: ATQ0 V1 E1 +FCLASS=0 ATQ0 V1 E1 +FCLASS=0 OK --> Sending: AT+CGDCONT=1, "IP", "internet" AT+CGDCONT=1, "IP", "internet" ERROR --> Bad init string. --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: ATQ0 V1 E1 +FCLASS=0 ATQ0 V1 E1 +FCLASS=0 OK --> Sending: AT+CGDCONT=1, "IP", "internet" AT+CGDCONT=1, "IP", "internet" ERROR --> Bad init string. To provide some background on my configurations: My wvdial.conf looks like this: [Dialer Defaults] Init1 = ATZ Init2 = ATQ0 V1 E1 +FCLASS=0 Modem Type = Analog Modem ISDN = 0 New PPPD = yes Phone = *99# Modem = /dev/ttyUSB0 Username = username Password = password Baud = 9600 [Dialer E1820] Init1 = ATZ Init2 = ATQ0 V1 E1 +FCLASS=0 Init3 = AT+CGDCONT=1, "IP", "internet" Stupid Mode = 1 Phone = *99# New PPPD = yes Modem = /dev/ttyUSB0 Username = username Carrier Check = no Password = password Baud = 9600 and my dmesg logs look as such: From these outputs, I infer (or possibly wrongly assumed) that my Huawei E1820 has indeed been turned into a modem and is ready for wvdial dialing. Additional Info: The SIM Card I'm using has been disabled of SIM_PIN and is bought from Chunghwa Telecom, a major telecom company located in Taiwan. ***Updated*** Hi all, I have tried changing my configs in the /etc/wvdial.conf file and now it looks as such: [Dialer E1820] Init1 = ATZ Init2 = ATQ0 V1 E1 +FCLASS=0 Stupid Mode = 1 Modem Type = Analog Modem ISDN = 0 Phone = *99# New PPPD = yes Modem = /dev/gsmmodem Baud = 460800 Username = username Carrier Check = no Password = password Now when I run wvdial, I get such error: --> WvDial: Internet dialer version 1.61 --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: ATQ0 V1 E1 +FCLASS=0 ATQ 0 V1 E1 +FCLASS=0 OK --> Modem initialized. --> Sending: ATD*99# --> Waiting for carrier. ATD*99# ERROR --> Invalid dial command. --> Disconnecting at Sat Aug 20 08:53:35 2016 I suspect that the reason for this is either: * the modem is not working as expected, or * the parameter Phone in the /etc/wvdial.conf file is not properly assigned. Hope I get this to work. Any ideas out there?

I am trying to establish a 3G connection with Raspbian, a 3G USB dongle, usb_modeswitch and wvdial. I followed this tutorial which has worked well before with a different 3G dongle. My 3G dongle is a ZTE D6601, the SIM has no PIN and the connection works flawlessly with the ISPs tool under Windows and under Ubuntu 15 with the built-in mobile broadband tool. But I need to do this on a Raspberry Pi and from the command line. This is what I have tried so far: When I boot Raspbian, lsusb returns Bus 001 Device 004: ID 19d2:0154 ZTE WCDMA Technologies MSM I then run sudo usb_modeswitch -I -v 19d2 -p 0154 -c /etc/usb_modeswitch.conf Which changes the ProductID to Bus 001 Device 009: ID 19d2:0108 ZTE WCDMA Technologies MSM There is more than one 3G dongle with 0154 as DefaultProduct ID so the standard switching rules of usb_modeswitch don't work. 0108 is what Ubuntu switches the device to or what happens when I sudo eject the virtual CD drive, so I used that. My /etc/network/interfaces was only changed to use a WiFi connection: auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 iface wlan0 inet manual wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp So far, so good. When I run sudo wvdialconf, a modem is detected at /dev/ttyUSB1. I then run sudo wvdial dcom with dcom being defined like this (APN "e-connect" is correct, no user / pass required): [Dialer dcom] Modem = /dev/ttyUSB1 Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 Init3 = AT+CGDCONT=1,"IP","e-connect" Stupid Mode = 1 Modem Type = Analog Modem Phone = *99# ISDN = 0 Username = { } Auto Reconnect = 1 Password = { } Baud = 460800 The shell returns this: --> WvDial: Internet dialer version 1.61 --> Initializing modem. --> Sending: ATZ OK --> Sending: ATZ OK --> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 OK --> Sending: AT+CGDCONT=1,"IP","e-connect" AT+CGDCONT=1,"IP","e-connect" OK --> Modem initialized. --> Sending: ATDT*99# --> Waiting for carrier.

ATDT*99# ERROR --> Invalid dial command. --> Disconnecting at Sat Apr 25 18:09:45 2015 If I run wvdial dcom again, it will repeat the output of the second connection attempt above (Invalid dial command) and not even configure ppp0. Weirdly, after a quick sudo wvdialconf (during which /etv/wvdial.conf remains unchanged), I can connect again, but it will again assign no IP and break after 10 seconds. I have replicated this several times. Maybe this is also interesting: wlan0 loses its IP the moment ppp0 is created and I can only get it back running sudo ifdown wlan0 and sudo ifup wlan0 even though it is set to automatically reconnect.

I use wvdial (PPP dialer) with a SIM card modem and sometimes this connection is reset by server side. I would like to run a script which greps ifconfig to get a volume of data downloaded and stores it somewhere. Obviously it has to be done when connection is still alive, otherwise I get nothing, or a few seconds later a value for fresh connection, because wvdial is configured to immediately reconnect when connection is lost. Any idea? **Edit:** Of course I can grep output of ifconfig every second or two, but this is horrible workaround not even worth considering. The best scenario I can imagine is to somehow capture the signal which instructs ifconfig to "reset the counting" => suspend signal for a moment => run my script => unlock the signal. But maybe there are other possibilities which I'm not aware of like for example configure ifconfig itself to dump the previous result to a file if given interface disappears. Another option is to take output not from ifconfig by elsewhere. BTW, what is the input source for ifconfig?
