Please update this post and keep it current:
ARM mbed now uses CORDIO as BLE implementation, and CORDIO is not activeley maintained and broken.
It would also be nice if the other statements are updated with newer findings ...

Hi guys! I am working on a project using nrf 51 and want to use Contiki OS on it. Is it sufficient to make some changes on nrf52 port to be supported by Contiki. If yes what are these changes ? Thanks !

Hi Eirik, Please update zephyr in your post:

Zephyr now supports nrf52 dk,nrf51dk,nrf51 ble nano and bbc microbit.

It is very interesting indeed, especially the RTOSes that have appeared recently. I cannot comment on plans we have at Nordic, but obviously we would be fools to ignore what is happening in the RTOS space. And if there is interest in the market it is even harder to ignore ;)

Thanks for your answer. The nRF52 has a lot of flash/ram, so in my case the size of the SoftDevice is not really an issue - lower power consumption is more important.

You post is interesting because they are quite a lot of (RT)OSes and IoT OSes out there. I would be interesting in reading a detailed comparison with for instance power consumption measurement for real applications.

You (Nordic) have you planned to officially support these OS in a near future ? Are you evaluating some of them ?

Yes, they both have open source BLE stacks. I don't have a full overview of the feature set, but the implementation seems quite feature rich.

If you care about power consumption and throughput I think the SoftDevice is the better solution at the moment, since it is heavily power optimized and the throughput is measured. I haven't seen numbers for the open source stacks. The main advantage with the open source stack is flexibility to add features, or remove features that are not needed in the product.

Zephyr and mynewt they both use Bluetooth from source, this means they use an open-source implementation of the BLE stack and a custom driver to use the nRF radio ?

What are the available BLE features for theses OSes ? What about the consumption and the BLE throughout ?
