@Lazar-Demin Thanks Lazar. Do you know roughly when the cloud will be back up? Are we talking weeks or more? I know you guys are under a great deal of pressure, and you work is truly amazing. Thanks for any info.

Fun checking the openwrt download repository
The repository seems to be down at the moment and if you do an update, it can wait forever to come back on its own.... So, I wrote a fun script to check first:
root@Omega-1F15:/usr/brian# cat ping_opkg
ping -c 1 -W 1 downloads.openwrt.org > /dev/null
Save the file as ping_opkg, and make it executable with:
chmod 777 ping_opkg
run like this:
It will either do the update or say, "Noooo!" if it can't and doesn't gang the system
RE: An external antenna..
Ahh - not to worry.. Just after posting, it took me to this page.. https://community.onion.io/topic/363/ufl-antenna-connector
That is exactly what I need.
RE: Hologram Cellular Expansion Docs?
Ohh - I have mine going but haven't installed the SDK yet, so I'll do you a trade..
As with any USB device, they have a VID (Vendor ID) and PID (Product ID). The linux device will see the VID and PID but you will have to tell it what hardware this is.. Is it a keyboard? Mouse? How can it communicate with the Cellphone modem? Looking at the docs for the UBlox Sara-201, it says that it has a few connections but one of them is an AT command set interface. Historically (if you are old enough to remember the 9600 baud modems we used to access the internet with in the early 90's...) modems with an AT command set are based on serial links. So in this case I took a guess and just said that the device is a serial device.
To get the PID and VID, you need to do the following:
root@Omega-F5C5:/usr/bin# lsusb Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 003: ID 1546:1102 U-Blox AG Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub root@Omega-F5C5:/usr/bin#
So, device 3 is the U-Blox cell phone module. The ID 1546:1102 id the VID and PID. CD to /etc/modules.d and edit the file usb-serial with the contents, "usbserial vendor=0x1546 product=0x1102 maxSize=2048"
This includes the VID and PID from the command, "lsusb" above and tells the omega that there is a serial port.
root@Omega-F5C5:/etc/modules.d# cd /etc/modules.d root@Omega-F5C5:/etc/modules.d# cat usb-serial usbserial vendor=0x1546 product=0x1102 maxSize=2048 root@Omega-F5C5:/etc/modules.d#
Install screen with opkg install screen
then cd to the /dev directory and ttyACM1 should be there
pipe the port to screen
screen ttyACM1 <enter>
and then you are connected to the modem. Try AT <enter> and it should say OK.
RE: Can I interface touch screen with Omega2 Processor?
These guys here do VGA interfaces and I have used them. They have touch screens and VGA controlled by a serial link that is really easy to use.
