How to develop open source software for nRF51 series?

I am also interested in open sourcing some work based on NRF51. I have been experimenting with the mbed API: mbed.org/.../ and that's starting to be usable.

I think mbed is supposed to be open source (Apache 2 license?), the Nordic code published on the mbed repositories so far has a mix of copyright headers though, some still claiming the code to be confidential, which is a little farcical when it was released by Nordic to a public repository, I presume that's an oversight but would be good to have clarity.

I would still love to see a more open release of the NRF51 SDK though... the mbed libraries are great for more easy-to-understand examples but not as flexible and currently don't feel quite "production ready". It would also help with the great annoyance that occurs every time Nordic release a new version of the SDK and I have to figure out what changed compared to the previous one, rather than just being able to look at the commits.

Please accept my answer, if this has answered your question. Thanks

Thanks. I hope the example code is provided under an less restrictive license soon.

For me a nRF8001 is no solution. I want to build some very compact sensors.

The linked nRF51 is a good point to start with.

Some of the nRF51 examples in github are released under a modified open source license, however these do not use the SDK and use the softdevice APIs directly. See http://nordicsemiconductor.github.io/nRF51-multi-role-conn-observer-advertiser/. Nordicsemi's Arduino SDK for the nRF8001 has been using the MIT license for some time. https://github.com/NordicSemiconductor/ble-sdk-arduino

Your request should be considered and it should be made easier to re-distribute code based on the nRF51 SDK.

" cannot use any of provided example code because its permits redistribution." I assume you wanted to say "prohibits re-distribution"

I've also started open source software here embeddedsoftdev.blogspot.ca/.../h.html. I have created my own exemple code too. You can always put your code open source. People can find a way to get the SDK. All you need to do is to point to where they can get it. I do agree that the example code from Nordic should be open. It will help people to make a sound decision whether the chip is the right solution by looking at the examples.
