@Lazar-Demin Thank you

No booting process with light blink
after powering it up, it is showing in attached image condition.

can you let me know how can i correct this if such condition occur in omega2.

Omega light is stable but it's AP mode is not showing "Omega-XXXX" through which i can connect.

Actually i was trying to factory reset omega2 using power dock. but due to usb disconnect factory reset stuck in the mid. and now whenever i do powering it up.. it is not showing booting process with light blinking.
when i plug power omega2 light get stable permanently and does not booting.

how can i correct it, now..?

Hello @administrators ,

Will you please let me know that why new firmware V0.3.2 is changing wlan0 MAC address, is this a bug OR onion is doing it legally..?

We are organisation and have lots of omega2, for which generated the serial number of devices on the basis of their mac address, now if I try to apply newer firmware it is changing my omega2's MAC address. i have purchased those omega2 approx 1 year ago.. and currently using version firmware v0.2.2 b200.

Suggest me, Please...

@Lazar-Demin Thank you

@Filipe-Madureira ,

I also had been facing same problem since last year. and have not got proper solution.
There is alternate solution through which i get out of this issue and that is power supply.

1. change the power supply Pin-board, that means plugin omega somewhere else from where you get proper supply (i got it by using this).
2. or change power supply mode through USB directly from your computer usb port.
3. or use a 3-pin adaptor/plug (i.e. which adaptor have 3 pin).

Hope this will resolve your issue.
i know this is quite not proper technical solution but beleive me i got it by using point no 1 and 3

Hello @Lazar-Demin , @administrators

Please help me out to find the real and working updated firmware, there are 2 places where omega2 updates resides:

1. https://api.onioniot.com/firmware/omega2/stable (which works through oupgrade command)
2. According to https://docs.onion.io/omega2-docs/manual-firmware-installation.html there is another location of firmwares which is http://repo.onioniot.com/omega2/images/

Now let me know that which firmware should i go through as both of the resources contain different version of omega OS...
i have 1-2 year older omega2 chip, will it be ok with newer firmware..? if yes then with which firmware point no 1 or point no 2

Please guid me

you can do the same by following below steps:

1. connect with Omega AP with default psk.
2. take terminal access through putty or any other software.
3. run command wifisetup
4. press 1 for scan network near by you. (you can also choose 2 and enter all details manually)
5. choose your network
6. choose your network security
7. enter password

it will take time of approx 5-10 sec and restart it's wifi adaptor and will get connect automatically.

Please let me know in case if by above instruction your issue didn't get resolve.

I think maybe this will help you guys to help me out, I am not using any language, for now, I avoid every language and following the instruction
UART Testing Basic Level as per Omega guidance link:: https://docs.onion.io/omega2-docs/uart1.html

and I found it fails as I had said earlier and as I was saying in my above queries, now please any professional guy there who can help me, please.
screenshot attached..!!

@György-Farkas said in UART Buffer is not containing data, while from other ends it ensures data is being written every second:

PySerial works with the full version of Python 2.7 only.

See Mr. Farkas, once again you treated me in such a way that I or our organization team does not know anything. but Thanks you, we need no reply from your side.
but for your kind information, i as myself has expertise in python, I can and have the abilities to customize any python package.

pyserial also works with python-light and we have delivered and made so many project.

for now i do not want to argue with you as i am not individual i am representing my company here, and looking for buffer solution.

please thanks for your reply, you are totally psycho i do no need of your reply. thank you very much.

Hey is there anyone else who can listen to me and can give solution with manner.

I have working python code, and working circuit which is going to be delivered to be our client AS an IOT device,
We are organisation and ordered huge amount of omega, and my team found some of the omega is not responding properly even by upgrading latest firmware.
Python code is working fine and circuit too with some of the omega2 but not working with rest of the.

Issue is ttyS1 always show as blank when I try to read it through same python code and also
Some of the pieces of omega2 is responding but in such manner like buffer “ttyS1” is not responding properly and seems like it hanging.

While entire omega is empty, no file no extra space occupied by us other than installing
Python-light and pyserial
I will try to share Some screenshots to you guys so that any professional guy can help me and my team from this.

Thanks
