Help me (Lars, of Underjord) make a really cool talk happen at Code BEAM Berlin. Add your devices to the pool of volunteers for weirdness. Join the fleet.

I promise to not do weird or creepy things with them.

Get the appropriate firmware for your device from releases. Please, refer to Nerves 1.10 targets and systems page to pick the appropriate release for your target device.

You'll need to install fwup if you don't have it. On Mac, run brew install fwup. For Linux and Windows, see the fwup installation instructions.

If you're using a WiFi-enabled device and want the WiFi credentials to be written to the MicroSD card, initialize the MicroSD card like this:

sudo NERVES_WIFI_SSID='access_point' NERVES_WIFI_PASSPHRASE='passphrase' fwup fleet.fw

You can still change the WiFi credentials at runtime using VintageNetWiFi.quick_configure/2, but this helps if you don't have an easy way of accessing the device to configure WiFi.

If you are using wired ethernet:

$ fwup fleet.fw
Use 15.84 GB memory card found at /dev/rdisk2? [y/N] y

Depending on your OS, you'll likely be asked to authenticate this action. Go ahead and do so.

Success!
Elapsed time: 3.595 s

You can then log in by figuring out what hostname your device got, something like nerves-ab12.local or the IP address via your network tooling. You can use any username (it is ignored) and it should prompt for a password. Password is fleet by default. Once in IEx you can run NervesHubLink.connected? and get an answer as to whether you are online. It should connect pretty quickly on boot but it can initially be tripped up a bit by clock-timing and NTP.
