Hi everyone
I cannot get LTE interface working properly with Quectel EC25-AU.
Any help would be appreciated.
Perhaps I have missed a step. Here is what I have done so far…
Installed Quectel EC25-AU modem into RBLHGR
Installed latest stable firmware Router OS 6.46.3
Installed latest stable LTE module 6.46.3
Using Ethernet cable between LHG and computer, connect using WinBox and MAC address
Perform router configuration reset
/system reset-configuration
Reconnect after reboot and configure USB modem connection parameter
/port firmware set ignore-directip-modem=yes
/system reboot
Modify default ppp interface ‘ppp-out1’ for modem and mobile network (APN: connect)
/interface ppp-client set ppp-out1 port=usb1 data-channel=3 info-channel=2 apn="connect" dial-on-demand=no add-default-route=yes default-route-distance=1 use-peer-dns=yes
Confirmed successful connection to Optus mobile network and confirmed successful routing of data using PPP interface
e.g. ping 8.8.8.8
Enable LTE interface mode on EC25 modem
First disable ppp-out1 interface
/interface ppp-client disable ppp-out1
Enter serial-terminal session with modem [note: channels 0 = debug (“DM”); 1 = NMEA (GPS); 2 = AT commands; 3 = PPP (or normal AT)]
/system serial-terminal port=usb1 channel=2
:test session
at
received:OK
:issue command to change modem to LTE mode
at+qcfg=“usbnet”,1
received:OK
:exit serial-terminal session
q
Perform router configuration reset again
/system reset-configuration
Reconnect using MAC address after reboot and confirgure Optus mobile network APN
/interface lte apn set numbers=0 apn="connect"
/system reboot
LTE interface shows an active session but no IP address or default route is configured:
Enabled LTE logging
/system logging add topics=lte
/system reboot
Log is attached below.
