World updates
If you've at all missed it. The Raspberry Pi 5 has been announced!
Headline features are the invention of the power button and something called a real-time clock.
Snark aside, whether it is worthwhile for your projects will depend on a lot of things. It seems to have a lot of improvements and be adapting a fair bit to how people have been wanting to use their Pis with expanded support PCIe and such. It is not the king of performance per watt. I found Jeff Geerlings video rundown of it helpful.
Project updates
This is a security/bug fix update for v1.24.0.
- Package updates
You know what this means.
System updates
- circuits_quickstart, v0.7.1
- nerves_system_mangopi_mq_pro, v0.6.1
- nerves_system_vultr, v0.21.1
- nerves_system_x86_64, v1.24.1
- nerves_system_grisp2, v0.8.1
- nerves_system_osd32mp1, v0.15.1
- nerves_system_rpi0, v1.24.1
- nerves_system_rpi, v1.24.1
- nerves_system_rpi2, v1.24.1
- nerves_system_rpi3, v1.24.1
- nerves_system_rpi3a, v1.24.1
- nerves_system_rpi4, v1.24.1
- nerves_system_bbb, v2.19.1
Other updates
- Changes
- Fix retry failure in up_cmds due to not cleaning up the existing bridge.
Fixed
- Workaround issue passing SSIDs that contain a lot of escaped characters. These were probably invalid anyway, but this prevents needless retries.
Changes
- Lowered log priority (warning -> debug) of several messages that occur a lot and aren’t really problems.
- Fixes
- Reset potentially outdated indexes when persisted logs are loaded. Fixes the case where the persisted logs might have a much higher index than the current buffer, so every new log gets added before the loaded logs
- Fixes
- Nerves.Bootstrap would fail to start in some cases where the dependencies had not been fetched and Nerves.Bootstrap would try to warn about the :nerves version requirement. This check has been moved to deps.precompile which happens after dependencies are fetched and also helps halt the build process if the :nerves version
Potentially breaking changes
- :nerves >= 1.8.0 is now required to use this version of nerves_bootstrap. If you keep up-to-date, then this won’t be an issue for you.
Updates
- Removed legacy tasks (tooling now maintained in :nerves)
New project generator updates
- Default to regulatory domain (00) for WiFi
- For US users, this means 5GHz won’t work anymore since it’s disabled in 00 (NO-IR = no initiating radiation) until you update your config to use US
- Bumped all Nerves systems to latest
- Default to regulatory domain (00) for WiFi
Community updates
Nerves Meetup online!
And the video is available. Hear Frank Hunleth talk about the latest updates and integration with Erlang OTP 26.
The next event happens on the 25th of October (26th for me).
Code BEAM Europe, Berlin, 17-20 October (SOON!)
(this was in the last one as well, keeping it in for practical information)
This conference is quite close for me and I can just go by train so the plan is to bring the full compliment of me and my team. The line-up is looking bad-ass!
On the Nerves-front we have the best-titled talk by Quinn Wilton. The Tamagotchi in my Hands: Anarcho-transhumanist Biohacking with Nerves. I expect she will blow us away. Abstract says Clippy is involved.
Sanne Kalkman is talking about tracking cats with the GRiSP board. Not sure if that's Nerves or mostly embedded Erlang.
Cocoa Xu will cover her work with TensorFlow Lite (tflite) which is very embedded-oriented. The embedded-friendly option for running ML inference using Nx and if you want to use Coral TPUs and such. Read more here.
The ladies bringing the embedded this time around.
I am going to be putting on the first live BEAM Radio with me, José Valim and Sasa Juric!
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.
- Give money to the project via Open Collective.
- 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.
