I found the problem gcc is not available in:
http://downloads.lede-project.org/snapshots/packages/mipsel_24kc/packages/Packages.gz

Go download the new packages from:
https://downloads.lede-project.org/releases/packages-17.01/mipsel_24kc/

just add:

src/gz reboot_base https://downloads.lede-project.org/releases/packages-17.01/mipsel_24kc/base
src/gz reboot_packages https://downloads.lede-project.org/releases/packages-17.01/mipsel_24kc/packages

in /etc/opkg/customfeeds.conf

This help may not be directly related to the Title, should I make a new Topic for this?

Hi
Here are the steps to deactivate the serial terminal:

• Open the following file: /etc/inittab
• It will look something like this:

::sysinit:/etc/init.d/rcS S boot
 
::shutdown:/etc/init.d/rcS K shutdown
 
::askconsole:/usr/libexec/login.sh

• To disable the serial terminal, the line with askconsole needs to be commented out, like so:

::sysinit:/etc/init.d/rcS S boot

::shutdown:/etc/init.d/rcS K shutdown

#::askconsole:/usr/libexec/login.sh

• Reboot the Omega and the serial terminal will no longer be available. Note that there will still be kernel messages printed, but the terminal will not be available.

Finally found a solution:
If you use your own custom webserver to setup the omega and want to display nearby Networks.

<?php
echo shell_exec("ubus call onion wifi-scan \"{'device':'ra0'}\"");
?>

^ This DOESN'T work! because:
the php-interpreter doesn't have enaught ram to excute the command. It'll take a eternity.

Solution:
in /etc/php.ini
set memory_limit form 8M to 32M

memory_limit = 32M      ; Maximum amount of memory a script may consume.

now the scan only takes about 5sec.

System:
Use Mqtt for the communication between your omegas. I would setup the raspberry as the broker.
SubSystem:
Read your device with the omega send the information to the raspberry via mqtt.
Output:
Display all Topics form the mqtt broker on the Raspberry.

Confirmed!

ApCli gets disabled after it fails.

Suggestion:

1. Have you made a ticket yet? Seems to be a problem we have no influence to.

2. Just don't put an "," in the password and let it be.

Install your packages

opkg update
opkg install libopenssl
opkg install openssl-util

Install offical firmware:
go to -> http://repo.onion.io/omega2/images/ download the latest firmware.
follow -> https://docs.onion.io/omega2-docs/manual-firmware-installation.html
Either install the firmware over a usb/sd-card or ethernet expansion.

Additional information:
LEDE wifi drivers doesn't work on the omega.

Hi
Some time ago I wrote about the nrf52840 form Nordic Semiconductor and that they would release the nRF52840 Dongle in end of june.
Well they finally released the dongle you can buy it from Mouser.

The idea is to make the Omega Thread, BT5 and ZigBee ready. I can't image a more compact gateway and server at the same time!

The possibilities are endless, what do you want?
With the implemenation of the nRF52840 DONGLE we can bring our omega projects a huge step further.

I have already done some work with the nRF52840 DK and it works great.
e.g. With an output power of +8dBm, I have a BT5 longrange signal of -90dBm, trought 2 reinforced concrete floors.

Image you can controll your ZigBee lights with you Phone without a cloud and at the same time connect all your omegas in a Thread Network.

@Paul-Abbott
Unless you make something custom you won't be able get something ~2$. The cheapest solution that might work is to get a HC05 form aliexpress or take a look at https://www.nordicsemi.com/eng/Products/3rd-Party-Modules.

Anyway I recommend an additional board or dongle for the omega. It's not worth to make something new in this case.

@Paul-Abbott
If you just want bluetooth 4, you won't need the nrf52840. It's just an feature of the chip.
I recommend https://www.adafruit.com/product/3405 as a border router. As soon as you want a web interface and some automations going on in the background, you might consider the omega or a raspberry pi3. It's easier.

The nrf52840 would be a overkill for you project. Especially because there's near 0 experience around and only 2 Development Kits. This is very experimental and time consuming.
My goal is it to have the same hardware for everything. Sensors and Actors that changes depending on your need.

• You want high throughput you change it to thread.
• Long range with bt5
• Compatibility with Zigbee
• Access the network directly with your phone over bt4. No over cloud communication

You can have up to 2 protocols running on one device. One is default and the other just for inputs.
I already have some DKs working like that. But there's still the question how I connect them to the internet. The omega with an usb dongle would be 1 of many ways to do so. This is what I'm working on right now.

I hope you get an idea what this chip is good for and if you like C and have some time get a DK or dongle and try it.

The part with changing the Boost Makefile is bullshit.
Singnals2 is inside Signals.
I tried doing the right configuration already in the configure part. but didn't succeed.

make clean
make
cd ../wpantund
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/home/fabian/test/source//staging_dir/target-mipsel_24kc_musl-1.1.16/usr/lib/pkgconfig

this time doesn't finde the dbus lib
wich is in /home/fabian/test/source//staging_dir/target-mipsel_24kc_musl-1.1.16/usr/lib/dbus-1.0/include/

In file included from wpanctl.c:47:0:

The package config path is defined to /home/fabian/test/source//staging_dir/target-mipsel_24kc_musl-1.1.16/usr/lib/pkgconfig
there is a dbus-1.pc file

pkg-config --cflags dbus-1
-I/usr/include/dbus-1.0 -I/usr/lib/dbus-1.0/include

it gives me the dir to the dbus lib where the dbus-arch-deps.h file is
why can't dbus.h include find this file?
any suggestions?

EDITED*
Hello
I can't cross-compile wpantund

setup
Ubuntu LTS 16.04

git clone git://github.com/OnionIoT/source.git
git clone git://github.com/openwrt/packages.git
cp -R packages/libs source/package
cp -R packages/utils/dbus source/package/utils
cd source
make menuconfig

add utils -> dbus + dbus-utils and libs -> boost -> singals

make #~30min-1h
cd ../
git clone git://github.com/openthread/wpantund.git
cd wpantund
sudo apt-get install dbus gcc g++ libdbus-1-dev libboost-dev libtool autoconf autoconf-archive
./bootstrap.sh
./configure --build=mips-openwrt-linux-gnu --host=mipsel-openwrt-linux-uclibc
wget https://raw.githubusercontent.com/OnionIoT/c-cross-compile-example/master/xCompile.sh
sh xCompile.sh -buildroot {"full path to source"}/source/ -lib boost

This will throw exception:

In file included from DBUSIPCServer.cpp:32:0:
DBUSIPCServer.h:29:37: fatal error: boost/signals2/signal.hpp: No such file or directory
compilation terminated.

it can't find the boost lib altough it's in source/staging_dir/target-mipsel_24kc_musl-1.1.16/usr/include/boost/
I'm sure, I missed something but what?
Thanks for help.

once more I answere my own question.
SOLUTION!
put this in a shell script and go for a walk, it will take some time:

if ! grep -q "src/gz reboot_base https://downloads.lede-project.org/releases/packages-17.01/mipsel_24kc/base" /etc/opkg/customfeeds.conf; then
	echo "src/gz reboot_base https://downloads.lede-project.org/releases/packages-17.01/mipsel_24kc/base" >> /etc/opkg/customfeeds.conf
fi
if ! grep -q "src/gz reboot_packages https://downloads.lede-project.org/releases/packages-17.01/mipsel_24kc/packages" /etc/opkg/customfeeds.conf; then
	echo "src/gz reboot_packages https://downloads.lede-project.org/releases/packages-17.01/mipsel_24kc/packages"  >> /etc/opkg/customfeeds.conf
fi
opkg update
opkg install grep gcc make autoconf automake tar
wget http://ftpmirror.gnu.org/autoconf-archive/autoconf-archive-2018.03.13.tar.xz
tar -xf autoconf-archive-2018.03.13.tar.xz
cd autoconf-archive-2018.03.13
sh configure --prefix=/usr
make install

done, have fun bootstraping (it's a pain)

Hi
Does someone know how to install autoconf and autoconf-archive correctly?

@CAP-33 said in Is it possible to make a connection to a certain Wi Fi network as a condition?:

uci: Entry not found

That means uci dind't find the enrty in the config file
try

uci show wireless

look for the entry that shows your ssid, it'll have a .ApCliSsid at the end.
copy that path and use it.

my fault
you need subprocess.check_ouput()

import subprocess
from time import sleep

ssid = subprocess.check_output(["uci","get","wireless.@wifi-iface[0].ApCliSsid"])

while True:
	if ssid == 'myssid' + '\n':
		print("Connect")
		print(ssid)
	else:
		print("No nonnection")
		print(ssid)
	sleep(1)

Hi
I'm not sure, if it's what you ment but.

install curl on omega:

echo "src/gz reboot_base https://downloads.lede-project.org/releases/packages-17.01/mipsel_24kc/base" >> /etc/opkg/customfeeds.conf
opkg update
opkg install curl
