Huawei ME909s-120 working config
I've got apu2d4 mainboard with Huawei ME909s-120 LTE module. It took me a while to get the modem going. So to help anybody else and for my own archive the config on how I got it working:
Interfaces / PPPs / Edit
Link Type: PPP
Link Interface: /dev/cuaU0.0
provider, APN, username etc according to provider
Phone number: *99#
Init string: Z
This config is working but after a reboot the modem is not reconnecting. When you save the PPP settings again the connection comes up again.
The solution to this is to install the shellcmd package.
Package / Services: Shellcmd Settings
Add a new command
Command: php -r 'require_once("shaper.inc"); require_once("filter.inc"); interface_ppps_configure("opt4");'
Shellcmd Type: shellcmd
replace opt4 with the optx of your network port.
