LTE Modem

Introduction​

The Omega2 supports the Quectel EC25/EG25 LTE modem which is enabled through a software package.

The modem is featured in the Omega2 LTE single board computer and enables a cellular data connection - LTE Cat4.

Maximum Data Rates: 150 Mpbs downlink, 50 Mpbs uplink.

Hardware​

The LTE modem must be connected to the Omega2 host USB port.

The Omega2 LTE single board computer features the LTE modem on-board.

Software​

To install the software package to provide support for the LTE modem:

  1. Flash the latest available Omega2+ firmware to your device – see installing the new firmware article
  2. Connect the WiFi – see the WiFi article
  3. Install the software
opkg update opkg 
install omega2-lte-base
  1. Follow the instructions from the Omega2 LTE Get Started Guide to setup the cellular data connection.
  • Safely ignore the /usr/bin/o2lte: line 134: /etc/init.d/ugps: not found message that comes up.
  1. Confirm the device is connected to the cellular network and the wwan0 interface has been given an IP address.

Caveats​

Using the Omega2 LTE with the latest firmware is a bit different. The new firmware is not the same as the v0.3.4 firmware for the Omega2 LTE.

Key differences:

  • There is no firmware specific to the Omega2 LTE. Instead, the Omega2 or Omega2+ firmware must be used. You can add LTE modem support by installing the omega2-lte-base software package.
  • The software does not include the ugps utility out-of-the-box. Additional work is needed to use the GNSS receiver.

We’re open to suggestions on improving this experience and software package. Please provide feedback by leaving a comment in this article. Or, create an issue in the OnionIoT/OpenWRT-Packages GitHub repo.
