Hello,
i want to control the relay expansion board with a self written python script. Therefore i followed this instructions:
https://wiki.onion.io/Documentation/Libraries/I2C-Python-Module
Consequently i installed the pyOnionI2C module and the "Omega Expansion" folder including the OnionI2C.so file are placed in the package path.
But when i try to run a python script including this line:
from OmegaExpansion import onionI2C
I get the following error message:

Traceback (most recent call last):
File "testi2c.py", line 1 in <module>
from OmegaExpansion import onionI2C
ImportError: Error relocating /usr/lib/python2.7/OmegaExpansion/onionI2C.so: i2c_writeBufferRaw: symbol not found

The firmware is up to date and I am using the omega 2.
Can anybody help me to handle this error or what modules do you use to communicate with I2C devicese?

Thank you,
Max

Hey,

what is the correct way to list the clients connected to the Onion AP (192.168.3.1)?

The most popular ways I found didn´t work:

I think nl180211 is the wifi driver but i cant find other openwrt systems with the same problem.

Is there a ubus function for this kind of scan?

Thank you
Max

@cas
Yes, if your script includes an infinite loop or never stops for other reasons the boot process will not end and the led kepps blinking.

You can tell the rc.local file that this script will not end by attaching an & behind the command.
E.g.: python /path/to/you/file.py &

Hey @Douglas-Kryder

I agree with you. So my question is how can I complete/fix the setup, because the wifi setup I did manually in /etc/config/network works fine. The Omega works as an AccessPoint, it is listed in my gateway, it can update opkg (I also can connect to the Omega itself and surf in the web). So for me the setup is finished but it seems I have to run a last script to tell the Omega the Setup is finished.
Can you tell me what you mean with "you can do it from command line or from console"?

Hello together,

i have never used the wizard or the console.
Just power the omega, connect directly to it, set up wifi and play with it via ssh in my wifi.

I noticed that the yellow status led of the ExpDock never stops blinking. But i ignored this because everything works fine.

But now I have noticed a problem: The ntp update dosen´t work.
When i type "date" the answer is

Fri Feb 3 09:07:16 CET 2017

Actually its Sun Nov 12 ... so everything seems to be wrong, not only the timezone.

Next I connected my second completely new Omega and followed the wizard. The yellow status led stops blinking after boot procedure and the output of "date" is correct.

Copying the options in /etc/config/system from the second Omega to the other doesen´t help.

Consequently, my question is:
Do i have to finish the configuration via ssh in a special way to use all services?
The blink behavior of the status led indicates me that something seems to be not finished correctly.

Thank you.
Max

Genius!
Thats it. Now it works.
Great, thank you very much.
I can´t imagine how I should find this little but important difference.
Hope it will help other people with the same problem.
