Stop whining and be a man.
If you wanna add something useful to the board, go ahead and show your arguments. Onion is far from perfect - I had issues with them myself - but let's be honest: your dissatisfaction is understandable, however, there are appropriate channels to solve your problems. Just show a little bit more politeness and they will be glad to help you.

As per stated here, OpenWRT/busybox(which onion is based on) does not support "@" expressions.

I almost forgot to mention: you can provide a better behaviour(considering you'll have additional options) using init scripts. You can setup one using the instructions provided here. I have done one last weekend to start my python app with little/no headaches. I suggest give it a try.

Hi all,
I though I was following the steps on the Cross-compile wiki, however, I certainly messed things up and, after some digging, I found the reason: I built and uploaded an openwrt firmware instead of omega's one.
I noticed that when I screen the tty and saw an "openWRT" logo, instead of omega's one.

Worse part is: I am not being able to connect it and download something(like an official omega firmware)(. I managed to get it connected to my router using wifi_supplicant, but I am not being able to download to anything.

Not sure, but is there any way to send files over tty? I tried with minicom, but no lucky at all.

Thanks in advance,
Vinicius

@Kit-Bishop first of all, sorry for the late reply.
Things must be on fire at onion due to o2. I got a gps as per your suggestion. Thanks a lot for your help.

Hi all,
I have not found the gps expansion for sale. Was it retired?

Thanks in advance,

Hi @Michal-Rok .
Python is an interpreted language, so this is usually slow during initialisation. I just created a small script that reads response from a rest service(http get) and print it on the oled expansion. It takes about 4 seconds to initialise. I believe that it's partially due to omega's hardware limitations.

So, if initialisation time is something crucial for your project, I would suggest look for some alternatives - namely C and C++.

Here are my 02 orders history.

First order(kickstarter campaign) - Taxed in about BRL35.00

• From witch country you ordered?
  Brazil
• Was there a tax free limit you could buy?
  Nope - tax free is only applicable for items shipped as "gift". All other cases are subject to eventual inspection/taxes.
• Is there a special place you could inform you (URL etc.)
  Not actually. I am just an experienced buyer
• Could you track your order?
  Yes, from China Postal service
• Probably would be also good idea to know if it was from kick starter or just from the online-store your experience?
  Kickstarter

Second order - from online store - No taxes were applied

• From witch country you ordered?
  Brazil
• Was there a tax free limit you could buy?
  Nope - tax free is only applicable for items shipped as "gift". All other cases are subject to eventual custom taxes.
• Is there a special place you could inform you (URL etc.)
  Not actually. I am just an experienced buyer
• Could you track your order?
  Yes, but this time I got a number from DHL.
• Probably would be also good idea to know if it was from kick starter or just from the online-store your experience?
  Online Store

Some tips:
1 - Brazilian customs does not inspect all shipments. They randomly select boxes to inspect. So ship your items separately on as much boxes as you can, so you reduce your chances to be taxed.
2 - Shipments sent by courier services(like Fedex and DHL Express) will always be taxed.
3 - The tax free for items bellow $50,00 and shipped by non-commercial individuals is BS. Customs agents are free to get any ship they would like to. There's a long time it's not valid anymore.
4 - The DHL global mail is not considered a courier service in Brazil, so it's not applicable to #2 rule.

Hope it helps

were you able to compile or something wrong happened?
If possible, would you be able to share the code using github or something else?

Looking for an alternative as well. The display quality is nice, however, texts are so small with the current driver.

You need to tell your router to provide the external address(also called WAN address) to your omega based on omega's mac address. This is also called DMZ or Port-forwarding.
Your mileage my vary, but this is possible to be done without much work. Call to your's ISPs support to get the right instructions.
