Using nRFgo Studio when producing 18000 units

[Hampus]

I need to do the following when assembling a device with nrf-52 at the factory.

• Add firmware onto device
• Add a unique serial number for the device
• Print a sticker and add on the outside of the device box with same serial number
• Test some basic bluetooth functionality

Would it be a good idea to nRFgo Studio for these tasks?

An alternative would be to make our own android application with a barcode scanner. A worker could then flash firmware onto the device -> scan sticker barcode with the android app -> connect to the device -> register serial number onto the device and test bluetooth functionality. But it sounds time consuming.

Any help on this would be very appreciated. How is this usually handled?

If you want to train your patience, it is good idea to use nRFgo Studio - it will take forever to click erase and flashing for all that units... For lower amount of chips, I would try some nrfjprog scripting, but for 18k units you need some better production programming solution.

Some info available here.

Thank you. I wonder if using a production tool like SEGGER J-LINK OB and Nordic's nrfjprog.exe combined if I can also test bluetooth functionality and make it print stickers. Do you know how flexible would it be? Flashing firmware and serial numbers to the device seems easy.
