Hello,
I have some trouble to start a 4G modem with connman.
- Raspberry Pi 3B+ with latest Raspbian Stretch (Linux 4.14.50-v7+)
- USB to MPCIE adapter with a HUAWEI ME909s-120 (4G Modem)
- connman 1.33
The modem is well detected on boot, we can see ttyUSBx ports and
ecm_ether port

$ ifconfig

??????? TX errors 0? dropped 0 overruns 0? carrier 0? collisions 0
a udev rule translate wwan0 to eth1 (eth0 is the ethernet port on RPI)
i can establish a connection with picocom on port ttyUSB2 and send AT
commands
$? picocom /dev/ttyUSB2 --b 115200 -l
Set the operator APN name to use for the data connectivity
AT+CGDCONT=1,"IP","hologram"
Activate the data connection for the network interface exposed to host
system with the APN profile previously created.
AT^NDISDUP=1,1,
Now the eth1 interface is running and receive it's IP address from the
network.
eth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>? mtu 1500

ping is also ok
