I am almost ready with a product containing a ItsyBitsy nrf52840.
It is a braille keyboard for blind users to connect to IOS devices.
We initially want to build a small production run.
Regardless of the number of products brought to the market we need a CE certificate in Europe.
(Similar to FCC in the US.)
For CE RED and EMV testing, the laboratory tells us that we need to bring the nRF52840 into an EMC-Testmode
In the Nordic nRF52840 SDK documentation I found this:
https://infocenter.nordicsemi.com/index ... erial.html
Here are my questions:
Is anyone here aware of this mode?
Can this mode be "activated" from CircuitPython? (currently, I assume not!)
In an ideal world, I would like to see a library with a function settestmode(mode) that would activate the different modes.
After this call the nRF Chip would be probably unusable for CP until the next boot...
Can anybody help with creating such a library?

Re: EMC Testmode for nRF52840
That library and the code that uses it are completely independent of anything in CiruitPython. The documentation you linked says it doesn't even need a BLE stack.
Your best bet will be to talk to the folks at the test lab to see if they're familiar with that kind of testing, and what they need/expect from you. It would also be a good idea to talk to the folks at Nordic to learn what they know about the testing process, and any tools or techniques that can help you.
You might also want to find a consulting engineer who's familiar with that kind of testing. Lab time is expensive, and someone who's done it before can save you from costly mistakes.
