Project updates
This update pulls in Buildroot 2024.02. This is a major Buildroot update.
Nerves systems need the following updates:
- For Raspberry Pi systems using libcamera, the version that comes with Raspberry Pi OS has diverged from upstream libcamera. To use it, replace BR2_PACKAGE_LIBCAMERA_*=y with BR2_PACKAGE_RPI_LIBCAMERA_*=y.
- The Raspberry Pi applications for libcamera also changed. Replace BR2_PACKAGE_LIBCAMERA_APPS=y with BR2_PACKAGE_RPICAM_APPS=y. The upstream package is called rpicam_apps. libcamera_apps was the old name.
Fixes
- Add explicit check for $TMPDIR to fix a regression on MacOS 13 with v1.26.1. Thanks to @schrockwell.
Package updates
System updates
Raspberry Pi
- Add back CONFIG_RASPBERRYPI_GPIOMEM to support the dht library.
- Linux 6.1.73 (Raspberry Pi 20240124 release)
- The libcamera and rpicam_apps packages have been replaced with the Raspberry Pi-forked versions for better compatibility. Please see nerves_system_br release notes.
nerves_system_rpi5, v0.2.0
nerves_system_rpi4, v1.27.0
nerves_system_rpi3a, v1.27.0
nerves_system_rpi3, v1.27.0
nerves_system_rpi2, v1.27.0
nerves_system_rpi0, v1.27.0
nerves_system_rpi, v1.27.0
Other systems
nerves_system_mangopi_mq_pro, v0.9.0
nerves_system_vultr, v0.24.0
nerves_system_x86_64, v1.27.0
nerves_system_osd32mp1, v0.18.0
nerves_system_bbb, v2.22.0
Enabled WPA3 support in wpa_supplicant. WPA3 won’t work, but specifying it in a configuration won’t crash the supplicant.
- Update Nerves systems to nerves_system_br v1.27.0 (Erlang/OTP 26.2.3, Buildroot 2024.02)
- Switch back to WPA2-only WiFi support with VintageNetWiFi.quick_configure/2 to fix issues on BBB and GRiSP2
- Fix regression that prevented WiFi networks from being provisioned on the MicroSD card
- Removed srhub target due to perceived lack of use. If this is not true, please open an issue and we’ll include it again.
- Update all dependencies to latest versions
Fix logic for detecting unconfigured WiFi networks
- Update Nerves systems to nerves_system_br v1.27.0 (Erlang/OTP 26.2.3, Buildroot 2024.02)
- Switch back to WPA2-only WiFi support with VintageNetWiFi.quick_configure/2 to fix issues on BBB and GRiSP2
- Fix regression that prevented WiFi networks from being provisioned on the MicroSD card
Non-system releases
Show backend options via backend_info/0 so that it’s possible to see whether you’re using CDev test mode or not.
iex> Circuits.GPIO.backend_info() %{name: {Circuits.GPIO.CDev, [test: true]}, pins_open: 0}
- Revert support for WPA3 with VintageNetWiFi.quick_configure/2. It caused way too many issues on some Nerves devices. The default is WPA2 like old times. Raspberry Pis, BBBs, and GRiSP2 don’t support WPA3 with their built-in WiFi modules so this may not impact you.
- Support use of WPA3 via an application environment option. See VintageNetWiFi.quick_configure/2 for details.
- Added VintageNetWiFi.network_configured?/1 helper function for checking whether a WiFi connection to another computer is possible or just scanning for access points.
- Added VintageNetWiFi.qr_string/3 to create QR Code-encodable strings for easily sharing network credentials.
- Added experimental VintageNetWiFi.capabilities/1 to query WiFi driver and wpa_supplicant capabilities. This can be used to check WPA3 compatibility, support for 5 GHz channels and more. It’s experimental since the information is currently very raw.
Don’t crash when logging corrupt data. This is not common, but can caused when logging output from system commands
Initial release
Improve error message when an OTP application isn’t found when building the OTP release script. It’s usually due to a dependency typo or wrong targets spec, so point to that.
Community updates
Nerves Meetup online :)
Next event is coming up on the 26th of April.
NervesConf, 9th of May
I am very excited to hit NervesConf and GigCity Elixir in Chattanooga this May. I will be speaking and so will many much more accomplished Nerves people. Don't miss it.
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.
