fm350gl_autostart for openmptcprouter

This project is used to set up the FM350GL modem in OpenMPTCProuter.

Description

Currently the support of the modem isn't that good, so you need to do some stuff on your own. Also it's not working very stable.

The project also includes a small luci interface to check signal quality.

Getting Started

Dependencies

• install kmod drivers and other tools

opkg update
opkg install kmod-usb-serial kmod-usb-serial-option kmod-usb-serial-qualcomm picocom kmod-usb-net-rndis usb-modeswitch
opkg install minicom socat luci-app-sms-tool sms-tool pciutils usbutils

• maybe you need to execute mode switch with:

# usbmode -s -v -c /root/usb-mode-custom.json

• you need to add an interface in luci
• assign it to your WAN firewall zone

Installing

• install the project under /root

git clone https://github.com/max93776/fm350gl_autostart.git

• you need structure as followed:

/root/Makefile
/root/autostart/at_commander.c
/root/autostart/at_commander_log.log
/root/autostart/fm350gl.sh
/root/autostart/fm350gl_sh.log

• change rules

chmod +x <file>

• build at_commander

make

• if you also want luci components in the right directory

make luci

Executing program

• edit the routes and names in fm350gl.sh according to your preferences
• in my case the gateway of the modem was marked as red if I don't change the routes after the manuell ip assigning in the script
• simply run in autostart dir

./fm350gl.sh

• if you want the modem to automatically start with the next powerup you need to add this line to your /etc/rc.local:

/root/autostart/fm350gl.sh

Help

• see logs for issues

cat fm350gl_sh.log
cat at_commander_log.log

• also show syslog

logread

• the script can print something like this to the syslog:

Oct  9 13:12:57 OpenMPTCProuter user.notice root: Script fm350gl.sh stared
Oct  9 13:13:19 OpenMPTCProuter user.notice root: Script fm350gl.sh ended
