Hi,

I have a bunch of notecards that interface with a MCU that run very similar firmware. I would like to provide these as binaries, but then I cannot hardcode the serial number and product. I believe that’s only necessary the first time the notcard is registered against my account, product, etc. Would it be possible to provide some interface where I provide the serial number of the notecard in notehub, so that we’re able to register and name the notecard without doing it from the notecard api?

Regards, Gaute

Hi Gaute.

You can register the serial number by setting an environment variable with the Notehub API.  
Use [Environment Variable API - Notehub API Reference - Blues Developers](https://dev.blues.io/api-reference/notehub-api/environment-variable-api/#set-environment-variables) to set the `_sn` environment variable.

I hope this helps.

Shouldn’t this be: [Device API - Notehub API Reference - Blues Developers](https://dev.blues.io/api-reference/notehub-api/device-api/#provision-device) ?

I always get invalid deviceUID, what should I use? I sent a support request since I don’t want to share product and deviceUID’s here.

Is this method documented for registering / provisioning devices _for the first time_?
