Hello.

Does anybody have a wvdial.conf file example for EP06?

2

Most of the time there is no need in using PPP.

I have replaced EC25 with EP06 and am finding some difficulties using the same script. Some AT commands (ex FCLASS) do not exist. I’d like to see another script example to adapt according to my needs.

Hello jfrog.

We are using EC25-AU model as our redundant WAN in an SDWAN solution and would like to improve it using EP06. We operate doing PPP data call to out local operators. We are using the script below to perform it using EC25AU. However, it is not working for EP06. Is there any change we have to do in this script?
echo “# Building wvdial.conf”
echo “[Dialer Defaults]” > /etc/wvdial.conf
echo “Init1 = ATZ” >> /etc/wvdial.conf
echo “Init2 = AT+CFUN=1” >> /etc/wvdial.conf
echo “Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0” >> /etc/wvdial.conf
echo “Dial Command = ATM1L3DT” >> /etc/wvdial.conf
echo “Carrier Check = on” >> /etc/wvdial.conf
echo “Modem Type = GSM Modem” >> /etc/wvdial.conf
echo “Baud = 460800” >> /etc/wvdial.conf
echo “New PPPD = yes” >> /etc/wvdial.conf
echo “Modem = /dev/ttyUSB2” >> /etc/wvdial.conf
echo “ISDN = off” >> /etc/wvdial.conf
echo “Auto Reconnect = off” >> /etc/wvdial.conf
echo “Phone = $LTE_NUMBER” >> /etc/wvdial.conf
echo “Username = $LTE_USERNAME” >> /etc/wvdial.conf
echo “Password = $LTE_PASSWORD” >> /etc/wvdial.conf
echo “Auto DNS = off” >> /etc/wvdial.conf
echo “Idle Seconds = 0” >> /etc/wvdial.conf
echo “Stupid Mode = off” >> /etc/wvdial.conf
echo “Abort on No Dialtone = on” >> /etc/wvdial.conf

I do not see any reason to use PPP in 2024.

I don’t know how to establish a wireless data link without a PPP connection using this kind of modem commanded by Ubuntu SO. Do you have any references on how to do it?

Every modern linux distribution has a ModemManager as a part of the network settings.

  • you can autodetect and locate your EP-06 USB modem device and show status:

mmcli --list-modems
mmcli --modem=0 # if modem number is 0 (located by a previous command)

  • Then you can list / read stored SMS

mmcli --modem=0 --messaging-list-sms
mmcli --modem=0 --sms=0

  • then try mmcli --help-all to list ModemManager options try to connect to the network manually then write your configuration to the network settings or to the NetworkManager profile
