Hi,
I’m having some difficulties getting the BG95-M3 to work in EMC or RMNET modes.
Linux Kernel: 4.4.194
Processor: Rockchip PX30
OS: Buildroot 2018.02-rc3
Firmware: BG95M3LAR02A03_01.014.01.014
ECM
AT+QCFGEXT="usbnet","ecm"
OK
I get the eth1 interface, it gets the IP address 192.168.225.20 from DHCP (I don’t know where it gets that address from), but ping 8.8.8.8 doesn’t work.
$ ifconfig eth1
eth1 Link encap:Ethernet HWaddr 00:A0:C6:51:E5:50

RMNET (QMI)
AT+QCFGEXT="usbnet","rmnet"
OK
I get a wwan0 interface, but it fails to obtain an IP address from DHCP
Output from some AT commands:

I would greatly appreciate any help making this work.
