NRF52 Zephyr or Mynewt Experience

[Justin]

I was just wondering if anyone has any experience with or thoughs about using Zephyr (www.zephyrproject.org/) or Mynewt (http://mynewt.apache.org/) that they would like to share?

[will]

Yes indeed! I have not used Zephyr personally but I have certainly used Mynewt (being one of the committers on the project). The latest development version of Mynewt has most of 4.2 implemented (with some exceptions) and is very liberally licensed (ASF). Should be very easy to get a project up and running on the nrf52dk. The project has been ported to the nrf51 and nrf52 so you can use either chip.

Not sure what exactly you are looking for but you can send emails to [email protected] to ask questions about the OS and BLE stack.

Hi Will!

Can Mynewt be used in production scenarios on nRF52, without the need to pay truckloads of money for FCC/radio certification? Or to put it in another way - do you use Nordics SDK in a certified way, via the official SDK?

[will]

You would need to get certified as Mynewt uses an open-source controller and not the nordic SDK/softdevice. The first release (beta) of Mynewt 1.0 is just about ready to be released but you would still need to get that certified.

[Henrik M.]

OK, expensive. So Mynewt is primarily for hobby projects, or do you know of anyone planning to pay the premium for certification?

[will]

No, I would not say that. Mynewt is certainly intended for production scenarios. I have heard of folks who are considering using Mynewt and they will get their devices certified. By the way, you might get a more comprehensive answer if you posted this question to the dev list: [email protected]
