@Paul-Abbott
Unless you make something custom you won't be able get something ~2$. The cheapest solution that might work is to get a HC05 form aliexpress or take a look at https://www.nordicsemi.com/eng/Products/3rd-Party-Modules.
Anyway I recommend an additional board or dongle for the omega. It's not worth to make something new in this case.
@Paul-Abbott
If you just want bluetooth 4, you won't need the nrf52840. It's just an feature of the chip.
I recommend https://www.adafruit.com/product/3405 as a border router. As soon as you want a web interface and some automations going on in the background, you might consider the omega or a raspberry pi3. It's easier.
The nrf52840 would be a overkill for you project. Especially because there's near 0 experience around and only 2 Development Kits. This is very experimental and time consuming.
My goal is it to have the same hardware for everything. Sensors and Actors that changes depending on your need.
You can have up to 2 protocols running on one device. One is default and the other just for inputs.
I already have some DKs working like that. But there's still the question how I connect them to the internet. The omega with an usb dongle would be 1 of many ways to do so. This is what I'm working on right now.
I hope you get an idea what this chip is good for and if you like C and have some time get a DK or dongle and try it.
Hi
Here are the steps to deactivate the serial terminal:
::sysinit:/etc/init.d/rcS S boot
::shutdown:/etc/init.d/rcS K shutdown
::askconsole:/usr/libexec/login.sh
::sysinit:/etc/init.d/rcS S boot
::shutdown:/etc/init.d/rcS K shutdown
#::askconsole:/usr/libexec/login.sh
The part with changing the Boost Makefile is bullshit.
Singnals2 is inside Signals.
I tried doing the right configuration already in the configure part. but didn't succeed.
make clean
make
cd ../wpantund
export PKG_CONFIG_PATH=$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?

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

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

What is <device>?
type ifconfig then you see all your devices.
what you look for is apcli0
iwinfo apcli0 info
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.
Hi,
@James-Thomas said in rc.local not working:
> # run the main program
> python /root/Flash.py >> /tmp/flash.log 2>&1 &
remove the second <&> you don't need it
python /root/Flash.py >> /tmp/flash.log 2>&1
Anyway you will have a problem logging files for a life time in /tmp. If you don't reboot your omega with cron every X days. The device will just stop working after a while, no space left...
You know theres a python module for gpio?
I often have the same problem with the micro SD card.
It happens when I factory reset my Omega with the SD card still mounted.
What works for me:
you might find this interessting https://github.com/JimJamUrCode/omega_garage
Installation:
I tried to install homebridge, but run into some errors.

Alternative:
I can recommend using homeassistant, works great.
Note:
Don't forget you will need to increase your memory and flash.
Looks like Nordicsemi will bring out a usb dongle with the nrf52840 in june.
That should make it easier to building something new with the omega.
Hello
Have someone already tried bluetooth 5 with the omega yet?
If yes I would love to hear your expirience.
I've ordered some nrf52840, I hope it works.
use the command:
wifimanager
if your service is still missing, factory reset your device.
