NRF Cloud & Developer account

Hi,

I would like some clarification regarding the use of a developper account.
I generated a Service Evaluation Token, tested with some queries, everything works.

Now, i want to generate JWTs for each of my devices.
I provisioned the device on the account ( like explained https://docs.nrfcloud.com/Devices/Security/JWT.html ), it's ok.

How then to retrieve JWT ?
On jwt.io, i fill in the different fields (uuid, ca private key and device public key), the signature isn't verified (i deduce that the JWT is false).

I tried ti generate directly on the device a JWT (AT%JWT), but if i use it (with postman, i get an error 40100, this ok with SET).

Is it possible with a developper account to perform location requests (gps) with JWTs for each device ?

Thanks for your help

PS: i'm not using a nRF9160 DK but an Icarus Board (i can do tests with a DK however).

  • I read and undestand but it doesn't help me.

    I did the steps:

    1. ProvisionDevices -> OK
    2. RegisterPublicKeys -> OK

    But i can't generate the good JWT for interfacing all.

    On first step, what should i put in Private Key ? I tested with the CA Certificare *.prv.pem

    On 2nd step, i tested with generated files (private_key.pem).

    None of these generated JWT works.

    I don't undestand what i'm doing wrong.
