Editor's note: We should now be back to our non-vacation cadence. Good to be back.

I also have a question from Frank Hunleth to the industrial users of Nerves, he is collecting some guidance for future choices. I hope this is not too late to be useful as I missed getting it into the previous one:

"Are any of the industrial Nerves users here having performance issues with Erlang and Elixir on your devices? If so, can you give any details? I know that most of you prefer to DM me and that’s totally fine. I’m trying to assess whether there’s interest in funding performance improvements that are specific to embedded and if so, what the pain points are."

If you can weigh in on that, find Frank on Twitter, in the Elixir Slack or via email I bet and you can share your insights. If you send 'em to me I'll pass it on too.

Official project updates

circuits_uart, v1.4.5

• Bug fix
  • Gracefully handle Process.info/2 returning nil (:heart: @tonnenpinguin)

vintage_net_wizard, v0.4.10

• Changed
  • Support WiFi modules that expose two WiFi interfaces - one intended for station mode and one intended for AP mode. This allows network connectivity to be checked while using the wizard. (@jfcloutier)

vintage_net_wifi, v0.11.1

• Changed

  • Added support for handling WiFi events. Currently events associated with WiFi AP associations are reported since they can be helpful when creating WiFi configuration user interfaces. More could be supported in the future. Thanks to @dognotdog, @THE9rtyt, and @ConnorRigby for this feature.
     

• Fixed

  • Remove mesh peers from reported access point lists. Mesh peers are reported separately and mixing them with access points was unexpected. Thanks to @mattludwigs for identifying and fixing the issue.

circuits_gpio, v1.0.1

• Bug fixes
  • On at least one device, the pin direction reported by Linux does not match the actual pin direction. This release forces the pin direction for inputs. It cannot do this for outputs, since setting a pin to output has a side effect on the pin state. This technically is a bug in a Linux driver port, but it was harmless to workaround for inputs so that’s what’s done. Thanks to @pojiro for investigating and fixing this issue.

MangoPI GPIO map
Alex McLain tweeted his contribution of a Mango Pi GPIO map for the Mango Pi system docs.

NervesConf II - Get it while it lasts!

NervesConf is making a triumphant return along with ElixirConf US over in Aurora.

Frank Hunleth has a good tweet teasing the planned hardware, it involves SIM cards.

Nerves Meetup - Workflows for Nerves

Jason Johnson's talk on Nerves Workflows from the meetup is up with slides.

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.
