How to develop open source software for nRF51 series?

[d00616]

Hello,

i want to develop open source software for nRF51 but i think the SDK licensing is to restrictive. I cannot use any of provided example code because its permits redistribution. So i must waste many hours to create own examples using available documentation. Why? Why its not possible to license all example code under an open source compatible license?

For me it's o.k. to sell an evaluation or development kit to get access to the SDK and softdevices but i want to share my code.

I'm sure making nRF51 SDK more compatible to open source software helps to sell much more MCU's and development kits. I think there is a big market for small and power efficient MCU's with BLE/ANT+ and open source compatibility. The question is what vendor provides this MCU first.

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.

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

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.

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.
