QR Code on Device

JFC

Sorry if this is documented somewhere, but there is a dot pattern that seems like a QR code on the 9160's exterior metal case. For the purposes of provisioning a product, does this pattern relate to anything unique to the device? If it related to the hardware ID or a modem parameter that would be helpful to know.

If the pattern is indeed useful in an assembly/provisioning context, is there a known good way to read it? The surface of the metal creates some difficulties capturing the pattern with a camera.

Thanks,

Jim

    as far as I know this is not necessary to provision the product. You can read this, it should apply to nrf9160.

    Hi Hakon,

    Thanks for your reply.  I should have provided some context.

    We are using AWS IOT Core, not Nordic Cloud.

    I am envisioning a manufacturing context where the worker connects the 9160 to a serial connection on a PC (Windows or Linux) then (possibly) scans the QR code on the 91xx module.  That kicks off a script that will generate (based on device-specific info) and install 

    cred_<device_id>_crt.pem

    cred_<device_id>_pub.pem

    cred_<device_id>_prv.pem

    into the correct slot on the modem hardware. Firmware load and testing would ensue.

    I wasn't planning to use the NRF Cloud but would like to find a firmware package that can receive and store the credentials. If that firmware can obtain and hand back to the PC the device-specific values for credential generation, that's even better. Is there a better way that Nordic customers are employing when provisioning their products?

    Thanks,

    Jim

    To my knowledge there is no way to do it the way you are describing. For getting started with AWS there are a number of resources available, including this guide. Hopefully that can be of some help.

    Thanks for the answer, Hakon. Actually our product is already working on AWS with certificates and the method I am using generally follows the resource you sent. As we are now in pre-production, I'm looking for is a way to automate this process.  I'll close this case and seek additional help.
