@Peter-Moellers so far we've only been testing with Mifare classic and ultralight. We'll make sure to get ahold of some DESFire EV1 cards and let you know how it goes!

RE: How to disable AP?
Just wanted to jump in and comment about this topic with regard to the WiFi Warp Core driver (b175 and up):
It is currently not possible to disable the AP and keep the WiFi client.
However, it is possible to configure the AP to be hidden (not broadcasting the SSID):
uci set wireless.ap.hidden=1 uci commit wireless wifi
2-Bullet Tuesday - Edition #64
Welcome back to 2-Bullet Tuesday, where we’ll share useful tips and awesome stuff sent in by Omega2 users all around the world. Check out creative projects and tutorials that will supercharge your IoT development!
RFID Access Control
This week our favorite project is an RFID access control system by Onion’s own Pavel Metrokhin! The project uses the recently released RFID & NFC Expansion to scan RFID tags and triggers an electronic lock to open when a trusted tag is scanned.
The project uses an Expansion Dock, Relay Expansion, OLED Expansion, RFID & NFC Expansion, a 12V Solenoid Lock and a 12V Power supply. The Omega holds a JSON list of trusted RFID tag IDs and everything else is controlled by a Python program that constantly scans for RFID/NFC tags and triggers the lock when a trusted tag is scanned.
So that’s that! A single command to run and voila, you have an electronic lock secured with your RFID tag. Now you just have to find something to keep safe!
Monitor your Battery Level with OnionOS
Last week, we released OnionOS, our all new web-based, graphical user interface. This week, we’d like to introduce a new OnionOS App: the Battery Level Monitor, for use with the Power Dock 2.
The App displays the latest battery voltage and a chart of the battery level for the last 24 hours - allowing you to visualize your battery usage. Once a minute, the App will talk to the Omega and grab the latest available readings. Right after the Omega boots, it will start collecting battery level readings, so the app will always have data to display.
Make sure to note that you’ll need to be using the Power Dock 2 to get the battery level readings. If you’re in need of a LiPo battery to use with your Power Dock 2, our friends at Sparkfun have quite the collection.
To install the Battery Monitor App on your Omega, run the following commands:
opkg update opkg upgrade power-dock2 oos-app-nfc-exp onion-os opkg install oos-app-power-dock-2 /etc/init.d/power-dock-2 start /etc/init.d/rpcd restart
If you’re thinking, “hmm that’s pretty clunky for adding a new app”, we’re with you 100%. We plan to spend some time improving this flow in the short-to-mid term, stay tuned!
As always, let us know what you think and if you spot any issues! Happy hacking!

RE: New OS Release!
@luz :D thanks for the great work!
@Volker-Helms @John_L @Paul-Cousins and others who have had issues with open networks or connecting in general:
we've taken a closer look at how the various encryption & cipher combinations work with the Omega and have made some fixes, so please checkout
Largest improvements are seen on open networks and WPA1.
Here's a full list of how everything works with
b178based on our testing:
- AES works
- AES+TKIP works
- TKIP works - observed connecting to network may take up to 30 seconds
- WPA (out-dated and should not be used)
- AES works - observed connecting to network can occasionally take a minute or two
- AES+TKIP works - observed connecting to network can occasionally take a minute or two
- TKIP works
- WEP (out-dated and should not be used)
- Shared Key Authentication works
- Open System Authentication does not work
- Open Networks (not secure and should not be used)
- Works as of
- Works as of
A few more house-keeping updates:
RE: After Warp Core upgrade, device unreachable
@Swapnil-Katpally After a factory reset, your Omega’s SSH signature will be different. You'll need to modify the
known_hostsfile on your computer.
See our Docs for more details: https://docs.onion.io/omega2-docs/factory-reset.html#a-note-about-factory-resets-and-rsa-key-warnings
RE: New OS Release!
More OS Updates, the very latest firmware,
b177supports I2S! See the blog post for more details: https://onion.io/2bt-april-3-2018/
@György-Farkas Are there any features that we need from the newer version?
@John_L We've confirmed there's an issue connecting to open networks, we'll be looking into this and will let everyone know how it goes!
