Cannot connect to operator (Orange (France))

adminAfs2r · May 22, 2019, 7:44am

Hello,

1°) I have a chat script to send to my modem (MC7455), but the dial command failed…

TIMEOUT 10
ABORT BUSY
ABORT 'NO CARRIER'
ABORT VOICE
ABORT 'NO DIALTONE'
ABORT 'NO DIAL TONE'
ABORT 'NO ANSWER'
ABORT DELAYED
"" ATZ
TIMEOUT 20
SAY "Connexion modem en cours... \n"
OK \d\d\d\d\d\d\d\d\d\d\d\d\d\d\d\d\d\d\dAT+CGDCONT=1,"IP","orange-mib"
OK ATDT*99#\ **=> This line failed**
CONNECT ""

It works well with a simcom SIM7100E… Maybe it is not the same AT command

2°) I need to configure this modem to connect in Argentina, what I have to change (from France) ?

Thanks a lot for your help !

Ok better, I needed to install GobiSerial and GobiNet drivers… And don’t forget to set RAWIP option to 1 in makefile before compiling

=> Download GobiSerial and GobiNet drivers from sierra website
# apt-get install make linux-headers-[kernel_version]-all-amd64 
=> Set var RAWIP to 1 in the makefile
# make clean
# make
# make install

Then, you have to blacklist the actual driver : qcserial

# nano /etc/modprobe.d/blacklist.conf : add this line : blacklist qcserial
# reboot

So right now ppp0 interface is up, but just for a while :

pppd[2969]: Serial connection established.
pppd[2969]: Using interface ppp0
pppd[2969]: Connect: ppp0 <--> /dev/modem_3g
pppd[2969]: PAP authentication succeeded
pppd[2969]: Could not determine remote IP address: defaulting to 10.64.64.64

pppd[2969]: remote IP address 10.64.64.64
pppd[2969]: No response to 4 echo-requests
pppd[2969]: Serial link appears to be disconnected.
pppd[2969]: Connect time 2.5 minutes.
pppd[2969]: Sent 2025 bytes, received 1027 bytes.
pppd[2969]: restoring old default route to eth1 [192.168.1.1]
pppd[2969]: Connection terminated.
pppd[2969]: Modem hangup
pppd[2969]: Exit.

=> No ping to google.fr but seems to have the DNS resolution… ?!
EDIT : no DNS resolution actually… It works when ppp0 goes down, and default gtw is set to ETH interface…

If you can help, please

Why do you use ppp?

After you installed GobiNet & GobiSerial make sure that the modem is attached to the NTWK.
at!gstatus? or at+creg
then establish the session use at!scact=1 (we also have QMI - checkout the QMI SDK or SDKlite)
on the host site call a dhcp client to transfer the IP address ( dhclinet)

Hello,

thanks a lot for your help !
I use ppp because it works well with my other modem (SIM7100E), and it was in place when I arrived in this company

=> All these commands are sent when the modem is disconnected (because it says it’s locked when it’s connected…) : so btw is there an option to connect to with minicom while the modem is connected ?

And sorry, but I don’t understand what means this sentence : “then establish the session use at!scact=1 (we also have QMI - checkout the QMI SDK or SDKlite) on the host site call a dhcp client to transfer the IP address ( dhclinet)”

Thanks again !

adminAfs2r · May 24, 2019, 8:26am

And I have already downloaded the SDK, to flash the modem firmware :

# ./bin/mc7xxximgmgmthostx86_64 -s ../../build/bin/hostx86_64/slqssdk
=> Option 3 : 
=> Flash with the file SWI9X30C_02.30.01.01.cwe (found on sierra website)

Hope I gave you enough informations…

Pierre

adminAfs2r · May 27, 2019, 6:47am

No idea ?

Oedenburger · May 28, 2019, 9:10pm

Hi Pierre,

PPP is obsolete, in theory it should still work, but we no longer test it.
I know some of our customers are still using it though.
The problem with PPP is throughput, the modem is capable of much higher throughput that PPP can support. (cat-6 300Mbps DL)
This could be an issue with some carrier certifications especially in the US.

Try not to program the APN and IMPREF in your PPP script.
BTW IMPREF requires a modem reset.

And sorry, but I don’t understand what means this sentence : “then establish the session use at!scact=1 (we also have QMI - checkout the QMI SDK or SDKlite) on the host site call a dhcp client to transfer the IP address ( dhclinet)

We also support QMI – a Qualcomm protocol – to control the modem. QMI is a more feature rich protocol than AT.

What I meant was, instead of PPP you have two options:

AT cmds
Make sure that the modem is attached to a NTWK
At!scact=1 – should return with OK
And call dhclient on the host side
(for this option no ppp or QMI is required)
QMI – we have connection manager sample applications under :
https://source.sierrawireless.com/resources/airprime/software/linux-qmi-sdk-software-latest/

“so btw is there an option to connect to with minicom while the modem is connected ?”
No only one AT is port is supported.
Ppp doesn’t utilize the modem’s RMNET port – which is dedicated for data.

Thanks,
James
