Hello,

I'm trying to setup a PLS8-E modem on ubuntu 14.02

I've tried various configurations but I always get +CME ERROR: 2 Invalid dial command.
I also tried to send a SMS message with gnokii and that works fine.

 root@wink-desktop:~# wvdial orange
--> WvDial: Internet dialer version 1.61
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Sending: ATZ
ATZ

--> Waiting for carrier.
ATDT*99#
+CME ERROR: 2
--> Invalid dial command.
--> Disconnecting at Fri Mar 25 06:19:51 2016

The wvdial config is:

[Dialer Defaults]
Stupid Mode = 1
Modem Type = Analog Modem
ISDN = 0
Phone = *99#
Modem = /dev/ttyACM1
Username = internet
Dial Command = ATDT
Password = internet
New PPPD = yes

[Dialer orange]
Init2 = ATZ
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init4 = AT+CMEE=1
Init5 = AT&W

Stupid Mode = 1
Phone = *99#
ISDN = 0
Modem = /dev/ttyACM1
Modem Type = Analog Modem
Baud = 115200
Username = net
New PPPD = yes
Check Def Route = no

Any ideas on this ?
Also I am unable to make the GPS work on any /dev/ttyACM

Thank you.

Hello,

Please check if there is a PDP context defined with AT+CGDCONT command. It is recommended to specify the context while dialling (e.g. ATD*99***1#). If parameter is not specified, then the first defined primary context is used.

ATDT seems strange but the 'T' should be ignored according to documentation. I'd try this manually. 

Please also check AT^SQPORT? reply to verify if you are using the modem and not application port.

Regards,

Bartłomiej

I've tested the  AT^SQPORT and I got the fllowing reply:

^SQPORT: Application

--> Modem initialized.
--> Sending: ATD*99***1#

ATD*99***1#
+CME ERROR: 2
--> Invalid dial command.

So it seems it's the application port. How do I change it?

Thank you.

You need to use at^ssrvset command.

at^ssrvset="current" - to check the current setting

at^ssrvset? - to list the possible settings

at^ssrvset="actSrvSet",2 - to set the service set number (2 in this case)

Restart is needed.

There are more possibilities - please see the AT commands specification document for details.

Regards,

Bartłomiej

I've tried ssrvset but it didn't work.
It was still on application mode.

Howerver now I am unable to contact the modem at all. None of the /tty/ACM* ports work.

Sorry, no modem was detected!  Is it in use by another program?
Did you configure it properly with setserial?

The modem is still present in lsusb and dmesg

Hello,

Could you paste the log for ssrvset configuration. Does it reply with ERROR or there's some other issue? Please check the firmware version with ATI1 command if it's possible. There was no ssrvset command in the old release 1. But you should probably have at least release 2.

Can you connect to the module with the terminal and send at commands to it on any interface? 

It would be the best way to configure it properly via terminal and then try with the dialling program.

Regards,

Bartłomiej
