Add OpenWrt 22.03.xx support to the Omega2LTE

[EpicLPer]

Context

openwrt-22.03

Motivation

It would be nice to have an up-to-date version of OpenWrt on the LTE model to use things like OpenVPN "out-of-the-box" without having to search for specific old versions, as example the OpenVPN SSL package would require some tinkering to get working.

Description

OpenWrt 22.03 would be a nice addition to have specifically for the LTE model.

Alternatives Considered

Flashing stock OpenWrt directly on the Omega2S+, however there is no image available for it yet.

Additional Resources

Reference to existing IPK package file?

@jempatel please pick this up next
To start, please just port the omega2-lte package to openwrt 22.03 and confirm it can run.

We'll discuss making an Omega2 LTE-specific firmware image after we get the package working

@EpicLPer ok, an package for the Omega2 LTE is now available for the OpenWRT 22.03-based firmware. I don't have an Omega2 LTE on hand to try it out - could you try it out? It is beta firmware, but it's stable for everyday use and you'll be able to go back to the v0.3.4 firmware anytime. Steps below:

• Flash latest beta firmware to your device - see https://github.com/OnionIoT/OpenWRT-Packages/blob/openwrt-22.03/technical-doc.md#installing-the-new-firmware
• connect to wifi - see https://github.com/OnionIoT/OpenWRT-Packages/blob/openwrt-22.03/technical-doc.md#sta
• install the omega2 lte package

  opkg update
  opkg install omega2-lte-base
  

• follow the instructions from https://onion.io/omega2-lte-guide/#getstarted-cellular to setup the cellular data connection

Let us know how it goes!

Awesome! Will test this tomorrow and report back then :)

Heya,

I don't see a specific firmware for the Omega2LTE, the very latest one I can find from yesterday is in this folder for either the Omega2 or Omega2P: http://repo.onioniot.com/omega2/images/openwrt-22.03/

Which one do I have to choose?

EDIT: Seems like I need to choose the Omega2P version, was confused cause before there was a separate firmware for each of them. Gonna try this one then :)

Gave this a try now, I did notice an error message when setting up my APN:

root@Omega-XXXX:/etc/opkg# o2lte apn a1.net
> Setting APN to a1.net
> Configuring network settings
[  774.495883] apcli0: deauthenticating from XX:XX:XX:XX:XX:XX by local choice (Reason: 3=DEAUTH_LEAVING)

/usr/bin/o2lte: line 134: /etc/init.d/ugps: not found

root@Omega-XXXX:/etc/opkg# o2lte data enable

> Done

Notice the /usr/bin/o2lte: line 134: /etc/init.d/ugps: not found line. I guess this is a package for the GPS component of the Omega2LTE which isn't yet installed, so it shouldn't matter too much. Tho for a stable release definitely important :)

[greenbreakfast]

@EpicLPer yep, for now Omega2 LTE support is in the form of a package and not a separate firmware. Sorry, should have highlighted that.
Yes, we have yet to port the ugps package. We may consider finding an alternative utility - less to maintain.

Were you able to confirm that you're connected to the cellular network and the wwan0 interface gets an IP address?

[EpicLPer]

@greenbreakfast Yeah so far everything seemed to work fine, updated/downloaded the packages and all :) Even the ugps package installed and I was able to enable it, however I couldn't test it as I don't have a GPS antenna at hand I could plug in.

[greenbreakfast]

@EpicLPer how did you end up installing the ugps package?

@EpicLPer how did you end up installing the ugps package?

I simply used "opkg install ugps" and it worked, then used the GPS enable command and it didn't complain about missing binaries anymore.

@EpicLPer Great to hear! Added brief documentation about this here: https://documentation.onioniot.com/hardware-interfaces/omega2-lte

I'm going to go ahead and close this issue as the Omega2 LTE is now compatible with the OpenWRT 22.03.5 firmware.
If there's more development/features that would be helpful to you for the Omega2 LTE, let us know by creating new issues!
