  Modems

  Correct, EC25-A modem for the North American model.
  The Global model uses the Quectel EG25-G modem.

  Images in Repo

  Fixed! The images are now in the repo.

  Wireless Carrier Support

  To see which bands are supported by the two different models, check out the chart here:
  https://www.crowdsupply.com/onion/omega2-lte#two-variants-for-global-compatibility

  gpsd

  It looks like gpsd has been ported to OpenWRT:

  https://openwrt.org/packages/pkgdata/gpsd http://trac.gateworks.com/wiki/OpenWrt/GPS

  You'll probably have to enable the OpenWRT repos on your Omega2 LTE to install it.

  See the guide in our documentation: http://docs.onion.io/omega2-docs/using-opkg.html#using-opkg-switch-to-lede-repos

  GNSS with No LTE

  Yes, it is possible to have the GNSS receiver and the LTE connection disabled. Just note that the modem will still likely fire up the LTE modem to use cell towers to assist in geo-location.

  libusb-1.0.so.0 is a symlink to the so, you can just create it :

  cd /lib
  ln -s libusb-1.0.so libusb-1.0.so.0

  You can try to re-deploy using the latest Onion build, which is running on the 4.14 kernel.

  $ oupgrade -l

  Be warned, though, I do not have good results running UART on this version. 0.2.2 b202 has other problems, but it is more stable for me.

  readValue needs to be passed as a reference, since the contents will be modified by the i2c_read function. That's likely causing the segmentation fault.

  Or change readValue to a point and allocate two bytes before passing it to i2c_read

  See the documentation for the i2c_read function for more details: http://docs.onion.io/omega2-docs/i2c-c-library.html#i2c-c-read-multiple-bytes

  However after 2~3 days running, the UART does not receive message.

  Dear William Scott, Bill.

  Thank you very much.

  I can send the message after stoppage of receipt. The write function is executed normally.
  Though read function is executed normally, my program can't receive any message.

  I made LED message receive/transmit checker at the other MCU.

  The MCU seems not to send/receive message.

  This serial port hang happens after 2~3 days from program running.

  Once this happens, the serial port does not work even though I re-run the program.

  If I reboot or power down/up agin, the serial port works.

  Thank you very much.

  @mawg You should see if it's possible to run GDB on your onion -- probably you'll want the Omega2 that has the most RAM, i.e. 2+. GDB offers things like breakpoints, stack-trace, read variables, capture on fault, etc.

  https://docs.onion.io/omega2-docs/c-compiler-on-omega.html

  Midway down this page, there's description on how to install gdb.

  @mawg if your asking do you need to do those commands, yes you do. if you did opkg update & opkg install ogps it would help to see the output of those commands. also a factory reset reinstalls the firmware already on the omega2.
  it will help in long run to update the firmware first.

  pyOnionGpio was written as a quick and dirty wrapper for the sysfs gpio interface. I wouldn't recommend using it for anything other than a hello world.

  There are other (likely better) sysfs gpio libraries available for Python3:

  https://pypi.org/project/gpio/ https://python-periphery.readthedocs.io/en/latest/gpio.html https://github.com/vitiral/gpio

  Let us know how it goes!

  @El-Berto this is an older mutex type, you may need to migrate the code.

  @Josh-Nussbaum erlang is available on omega, just edit /etc/opkg/distfeeds.conf and uncomment lines 2 and 5. Then run

  opkg update
  opkg install erlang

  @Maurizio-Messa Here is grasping at straws, but..... The time or three I've seen a failure to sync I was able to fix the problem by reflashing the device. See https://docs.onion.io/omega2-docs/factory-reset.html. Ought to take just a few minutes.

  Again, grasping at straws. If that doesn't help I'll take a more detailed look at it.

  take care!

  @Aquiles-Castro Have you looked at PicoLisp? Last I looked it did not have a compiler so it's purely interpreted but I'm not sure what you need. I don't use Lisp but my colleague thinks it's pretty useful.

  Installing pysnmp module for python

  This was with me actually installing pysnmp on the omega with "pip install pysnmp", so it was trying to compile it on the omega and I'm guessing even if I did "pip install pycrpytodomex" it would have had the same results.

  installing gcc, after uncommenting the base and packages lines for openwrt in /etc/opkg/distfeeds.conf, seemed to do the trick. Though, I ran into another problem. It ran out of free space, not on my sd card, but on the /tmp mount. I'm not sure how to increase that, or if I really need to, but for anybody else that might come across this the solution was to specify a build folder for pip like this.

  pip install --build /root/tmp pysnmp
