Claim

This guide helps device makers to claim Microchip ATECC608 secure elements on The Things Join Server.

Prerequisites

1. ATECC608A-TNGLORA or ATECC608B-TNGLORA secure elements. Product details
2. Device security (manifest) file. You can obtain this from your Microchip Direct order history
3. Provisioner access to The Things Join Server. Contact The Things Industries support to get access.
4. The Things Join Server command-line interface (ttjs) installed. See instructions to install ttjs

Initialize ttjs

To initialize The Things Join Server CLI ttjs, run the following command:

ttjs init

This prompts the URL, provisioner credentials and location to save the configuration:

✔ Server URL … https://js.cloud.thethings.industries
✔ Provisioner username … example
✔ Provisioner password … ********************
✔ Configuration file … ~/.config/ttjs/config.yaml
✔ Save configuration … yes

Verify that your credentials are correct:

ttjs list

This should return the currently provisioned devices (or [] if there aren’t any).

Import manifest

Next, import your manifest file, in this case named manifest.json:

ttjs import -f microchip-atecc608 manifest.json

This provisions the secure elements in The Things Join Server and returns the generated owner tokens, for example:

[
  {
    devEUI: "0004A310001AAED6",
    ownerToken: "C05EA29C",
    rootKeysExposed: false,
  },
];

The owner token is called claim authentication code in The Things Stack. This is the proof of ownership for claiming devices. See Device Claiming for more information.

Export root keys

In case your end devices are to be activated on a LoRaWAN® Network Server that does not support claiming on The Things Join Server, the root keys can be exported:

ttjs get <dev-eui> --nonces --root-keys

This returns the root keys and LoRaWAN nonces (if any):

{
  devEUI: '0004A310001AAED6',
  ownerToken: 'C05EA29C',
  rootKeysExposed: true,
  nonces: { nextJoinNonce: 2, usedDevNonces: [1836, 10331] },
  rootKeys: {
    appKey: '525746CCF9CF5DE887BE5D836D08B5C9',
    nwkKey: 'CB0F4E236567566D2A976B3DAB2CF7A5'
  }
}

This allows you to register the devices on any LoRaWAN Network Server that does not support The Things Join Server.
