@György-Farkas Interesting, I did check on an Omega 2+ running 0.3.2 b200 and executing the command did nothing. I power cycled it, and the LED blinked through the start up pattern but the Omega-XXXX network never appeared. Now that Omega 2+ will not even start and has discoloration on the shield near the U.FL port.
I just reran the commands on an Omega 2 running firmware 0.3.2 b222 and it worked! There was no lag when the local wifi router was disconnected. Thank you very much!
I'm hoping someone with more experience than I has some ideas on what is going on. First I tried following the Onion Omega's own documentation The Omega as a Router but running the command
uci set wireless.@wifi-iface[0].ApCliEnable=0; uci commit wireless; wifi
(which supposedly disables the ApCli device which is used to wirelessly connect to an existing router) does cause me to disconnect from the existing network and I still have internet through the omega. The only way to disconnect from external WiFi network is to is to turn off the virtual interface wwan using
ifdown wwan
However even with wwan disables and ApCli device supposedly disabled, if I turn off my home networks wifi router and ssh into the Omega2 through its wireless AP, the session is still laggy. If I turn my wireless network back on, even though the Omega2 does not report internet connectivity; and wwan and ApCli device are still disabled; the lag goes away.
What configuration option am I missing?
@György-Farkas said in Onion Omega 2/2+/2S+ access point slow without external wifi network:
uci set wireless.sta.disabled='1'; uci commit wireless; wifi
Thank you very much for the reply! But those commands seem to disable the WiFi all together. I need a standalone WiFi network for the project I am working on. I am trying to disable the second virtual interface on the Omega that connects to another network while leaving the first virtual interface, the Omega's WAN, since the Omega seem to work poorly when there is no external network to connect to. Hopefully that makes sense.
All,
I'm try to fix an issue I am having with really any Omega 2/2+/2S+ I own. Basically everything works fine when the Onion Omega 2/2+/2S+ is powered on in my apartment and connected to my home wifi. I can connect to Omega 2/2+/2S+ access point with my laptop, and ssh into the device with no lag. As soon as the Omega 2/2+/2S+ is outside my apartment and is no longer connected to an existing wireless network, I can still connect to the access point with my lap and ssh into the device, but it is incredibly slow. I will get the same performance as if I was back in my apartment for a brief period of time, and then it will become unresponsive and I have to wait a minute or more before the ssh terminal will update.
I'm assuming this behavior is due to the Omega 2/2+/2S+ searching for a network for it to connect too, but I'm not sure. Is there any way to disable that functionality to test? While I would call myself acceptably versed in Linux, I have not played with the OpenWRT enough to fully understand the UCI configurations or the proper way to make this change.
Any advice?

Edit: I realized I forgot to mention I am using firmware B200 and B221
@Douglas-Kryder The hardware files are on the github here along with directions for ordering the PCBs. It's currently $8.40 for 5 with free DHL shipping from JLPCB.
Hello!
I just wanted to share a project I've been working on for the last year or so as an outreach tool for some of the departments here at Virginia Tech. It a low cost (~$30) onion omega2 based robot which is controlled through a webpage hosted on the onion omega itself. Its completely programmed in python and javascript, and is controllable from any device that can open a web browser. It features differential drive and speed control through either a real world or virtual joystick/gamepad.
In addition, an onboard accelerometer allows it to detect collisions and perform obstacle avoidance (if you program it to!) and lights up an autocycling RGB led after impact. It uses a protected 18650 cell with an onboard USB charger.
The intent was to develop a platform that was cheap enough to give away to students who wanted to build one, and it is currently being used in a high school summer camp program.
All software files and the hardware gerbers are up on the github: github
and the build directions and BOM are on the github wiki: github wiki
The hardware files and ordering directions for PCBs are up here
If you are curious the design process struggle was documented (poorly) here
Hope someone finds this interesting or useful!

Doubt it is helpful, but I can confirm that I2S audio as an output is not functional on firmware b221, b200, b196. The only firmware version I had working audio on was b193, b180 and b177. (I assume it works from b193 to b177, but I only tested b180) This was all tested on the same onion omega2+ with a MAX98367A I2S mono amp breakout board from adafruit.
It would be nice to have working I2S and hardware PWM on the same firmware.

All,
I have poked around a little bit, but I could not find an existing python wrapper for the fast-gpio command line utility. Does one exist? Finding omega-related code online is suprisingly difficult, and I am not quite sure why.

P.S. Yes I know I could write my own fairly quickly, but it is always nice not to reinvent the wheel.
