Lost knowledge
The Nerves core team are making the same move that Ash Framework recently did where we shift our answering of questions and troubleshooting to be on the forum. The goal of this is to build up a knowledge-base that doesn't scroll away into Slack's hidden history or Discord's app-only archive. We want Nerves to be findable via Google. The Slack and Discord are both fine places to discuss, show things and that is also welcome on the forum.
Have some patience with us as we get into the habit of tracking the forum for questions and generally find the swing of things. Over time this is bound to improve both the perception of Nerves usage (Ash had a lot of users and no-one knew :) as well as how easy it is to find answers. The Elixir Forum is a unique thing in our community where we don't need to rely on Stack Overflow for a platform. Time to use it for Nerves.
You can subscribe and watch parts (such as the news, or the chat) or the whole of the Nerves forum and get email about things that happen if you want to stay on top of things. Lots of functionality is suddenly available for following along with Nerves.
Project Updates
This update pulls in Buildroot 2024.08 and Erlang/OTP 27.1.1. This is a major Buildroot and Erlang update.
If you’re updating from Nerves systems earlier than 1.28.0, please see the 1.28.0 update instructions below.
Changes
- Add patch for wpa_supplicant to optionally enable PKCS11 support. This allows hardware security modules to supply 802.1x or WiFi credentials.
- Strip write-only executables files included in releases. This is needed for the XLA shared library.
Package updates
- Updated
- Change to only configure if connecting (#229)
This was primarily a problem if you were simulating a device or you had a device that should start and stop NervesHubLink dynamically. Typical if your device doesn't have a NervesHub configuration from the start and is intended to be onboarded.
- Bug fixes
- Fix several issues found with clang’s -fsanitize feature. Thanks to @jbnoblot for reporting them. See #114 for details.
- New project generator updates
- Fix dialyzer warning in generated project
- Adjust Erlang doc URLS in vm.args.eex to the new locations
Nerves support is shifting to Elixir Forum - Nerves Forum! This will now be the preferred and primary source for gaining Nerves support and documentation has been adjusted to reflect this shift.
- Set TERM from user terminal when running mix nerves.system.shell on MacOS. Fixes an issue where config menus were not rendering
- Documentation updates and improvements
- Add instructions for mise
- Remove USB Gadget mode serial references since not on official platforms
- Bug fixes
- Don’t crash on ENXIO (errno 6) failures due to unresponsives I2C targets
- Add ENXIO as a known error for easier debugging next time

No more space at the Nerves Workshop, 13th of October, Berlin
The Nerves workshop in Berlin is full.
If you are going to the workshop or are on the wait list for the workshop I suggest also attending the Meetup that is happening after. It seems like Frank will show the guts of a SmartRent Nerves device there. Should be a fun time :)
Anatomy of Embedded Elixir
I (Lars) wrote up this post trying to share my evolving understanding of Nerves. Hope you enjoy.
Nerves Meetup: Nerves on Spotify Car Thing
Eric Rauer joins the Nerves Meetup to show his efforts of turning abandoned hardware into something you can run Nerves on. Super interesting thing as the Spotify Car Thing goes end of life in December.
Check the event information for details. End of October.
Participating in the community
The Nerves community is found wherever Elixirists gather. Try any of the following:
- Elixir Slack, #nerves channel
- Elixir Discord
- Mastodon/Fediverse at genserver.social
- Elixir Forum Chat
Supporting the Nerves project
We want to encourage everyone to contribute in whatever way works for them. Here are some ways we currently recommend:
- Write or port a new hardware library and include it in the Elixir Circuits collection.
- Get in touch about taking over maintenance duties for some libraries, we might be able to provide you hardware.
- Apply for an EEF stipend on something Nerves-related and build it. We can help if you have questions about this.
- Send corrections or improvements for documentation wherever it fails to help you.
- Write about Nerves, give talks about Nerves. Make videos about Nerves. It is all good.
Finally, if you have questions about the newsletter or want to suggest something you can simply respond to this email it will go directly to me, Lars, who edits this thing. Let me know what you think.
