IEEE802.15.4 support for nRF52 and nRF53

[raiden00pl]

For now only BLE is supported for nRF5x. IEEE802.15.4 will enable Thread support for Nordic chips. I have it partially done, but I don't know when I'll finish it, so I'm starting an issue to track any progress.

• [x] IEEE802.15.4 support for nRF52 - https://github.com/apache/nuttx/pull/11617
• [ ] IEEE802.15.4 support for nRF53 - TBD

I would very much be interested in this and could potentially help with testing/adding features. @raiden00pl

@raiden00pl Can you give an update on your progress?

I have received some funding to develop Thread support for nRF5x on Nuttx and I would love to build on top of your work.

Thanks!

Hi, almost no progress. I bought a handful of mrf24j40 modules (supported in NuttX) and put them in a pile on my desk with the rest of the devkits waiting for my attention :) . I'm doing other things now and I don't really have the time or motivation to do anything with this topic.

I'll review and prepare my changes next week and post the link to the branch here

Ok, too bad. In the title and your original post you mention nRF52x chips. Did you also work on these or only mrf24j40 modules?

[raiden00pl]

This issue is about IEEE802.15.4 support for nRF5x using the build-in radio. The only purpose why I need mrf24j40 is for testing and a better understanding of how MAC layer works on NuttX.

Here's the draft PR : https://github.com/apache/nuttx/pull/11617

There's still a lot of work and testing to do. I'll come back to this probably next weekend.

I'm reopening it because nrf53 has not been done yet
