We have seen people occasionally struggle with the somewhat outdated documentation of NervesHub. We are working on a larger overhaul. Until then we have gone through and removed outdated information and refreshed the details.
To help with the immediate challenge we launched two new tutorials for setting up devices with an existing NervesHub install such as NervesCloud (free for enthusiast use) or one you host on your own. The first is the quickstart which gets you up and running as quickly as possible for development, experiments, hobby use and prototyping. It uses the Shared Secret approach to authentication. We also offer the production guide which includes using a NervesKey hardware chip and device certificates and options for enabling JITP (Just In Time Provisioning).
Check them out, get your devices updating remotely and enjoy the new functionality that keeps showing up.

NervesConf US
It is imminent or has just happened. I am terrible with timezones. I hope someone is willing to provide a report for us later. Just wanted to shout at everyone there that we who are not are very envious and to have a ton of fun on our behalf. Speak well, listen well and enjoy your peers!
Igniting Nerves
May 14th
, Krakow, Poland
Register here to attend
Before ElixirConf EU this year Underjord & Nerves are joining forces with Zach Daniel to integrate Igniter to help install, setup and developer experience for Nerves.
This is a superb opportunity to get your first PRs into Nerves projects. Requires Elixir ability but not particular Nerves experience and no hardware at all.
Free workshop where we mostly hack on things.
The first NervesConf EU is coming. It'll be a blast!
Travel and hotel information is now available.
CFP is closed. Line-up will announce soon and I could not be more excited!

Others parts
I posted a bit about the recent improvements to the NervesHub CLI , also about the Swagger API view and such.
Nerves system: ReComputer
Aldebaran contributes the work he has done to enable Nerves with the Seeed Studio ReComputer R11xx series.
This is a neat Raspberry Pi 4 Compute Module-based machine that is intended for industrial environments.
Nerves Meetup (remote)
Check out the event page for the next event, end of May.
Error reporting in production?
I posted a question about what people use for reporting errors from devices in production. I'd love to hear from you all as this might influence how we deal with error reporting for devices connected to NervesHub.
Got questions?
Trouble-shooting is best done on the Nerves Forum over at Elixir's Forum. But if you have big-picture questions you would like to ask around Nerves, feel free to send them in and we might just have ourselves a column here.
Nerves and Elixir shirts can be bought at
oswag.org
. Stickers with every purchase.

- 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.
Finally, if you have questions about the newsletter or want to suggest something you can simply respond to this email.
