Page 3: The Hardware
1. The hardware 1.1. Specifications Mifi dev board is developed using Domino Core and Industrial PCIe 3g/4g modules, targeting as industrial grade applications and hobbyist projects. We are continuing to improve the product so the final product many differ from the pictures. Atheros AR9331, @400MHz Memory DDR 64MB/ FLASH 16MB... -
Page 4: Reset Button
The newest firmware configure it as LAN by default. Plug a cable to it from your computer will get an IP address. 2. Compatible 3g/4g modules GL-Mifi is compatible with most PCIe 3G/4G modules. We have three modules tested. • Quectel UC20, •... -

7. If the console displays ttyUSB0, ttyUSB1, ttyUSB2, ttyUSB3 and ttyUSB4 (as figure shown below), that means GL-MiFi identified the module and we can then configure the MiFi. For Quectel EC20, and UC20, both the data port is /dev/ttyUSB3, the AT command port is /dev/ttyUSB2 For Huawei ME909s-821, the data port is /dev/ttyUSB0 3. -
Page 6: Using Winscp Via Ssh
1.5. Using winscp via SSH If you are using Windows, winscp is a good tool to manipulate the settings. First connect to the board using winscp. Second, modify file content directly. If you want to modify network configuration, “/etc/config/network” is the correct file to modify. -
Page 7: Change The Ethernet To Wan Or Lan
For 4G-LTE, change the service to “fdd-lte”, for 3G umts, change service to “umts”, for evdo, change to “evdo”. After you change the settings, restart the network: /etc/init.d/network restart If you are sure that your settings are correct, after restarting the network or restarting the router, you keep getting “error -2”... -

Page 11: Compile Your Firmware (Ubuntu)
opkg update opkg install [package name] The current firmware is still an engineering firmware so you may not install kernel modules directly in this way. You can compile your own firmware. 6.2. Compile your firmware (Ubuntu) ATTENTION: A firmware compiled using the following steps seems not works with EC20 4G module correctly. Still checking the problem. -

Finally, you can get what you want firmware at [openwrt-mifi/bin/ar71xx/],firmware’s name is [openwrt- ar71xx-generic-domino-squashfs-sysupgrade.bin] 7. Troubleshooting No ttyUSB0~ttyUSB4 This generally means the driver is not installed or the module is not recognized. You may need to check the connections of the module Field: [option_instat_callback: error -2] appears after startup For some complicated reasons: (1) Bad contact of SIM Card.
