LTE Support on LinkE362 modems are supported on the Link platform because the make.conf file specifies USE=modemmanager-next. There should be nothing special you need to do, other than to make sure that you are running shill and not flimflam.
LTE Support on AlexFor developers using older hardware, e.g. Alex, the following instructions are still relevant.
How to set up to manually test and use a Novatel E362 LTE modem (updated 2012-2-14)
(This should all be handled by Shill in the near future)
You will need:
- ChromeOS dev system
- ChromeOS device with an E362 + appropriate SIM
On your dev server, in the chroot, run:
emerge-${BOARD} --unmerge net-misc/modemmanager modemmanager-next-interfaces virtual/modemmanagerstart-devserver
On the device, as root, run:
stop modemmanager
mount -o remount,rw /
emerge --unmerge net-misc/modemmanager modemmanager-next-interfaces virtual/modemmanager
Set up the network to dev server, USB ethernet or whatever, in your usual manner, and run:
USE=modemmanager_next gmerge --accept_stable virtual/modemmanager
start modemmanager mmcli -L
mmcli -m 0
Confirm that the modem is detected - this command should produce about 20 lines of status about the device.
To connect:
ifconfig eth0 down
mmcli -m 0 --simple-connect=""
ifconfig eth0 up
This last command triggers flimflam to run DHCP and configure the interface.
-> Make sure you unplug USB Ethernet devices and disable wifi before running speedtest or similar!
To disconnect:
mmcli -m 0 --simple-disconnect |
