nRF51822 : open source firmware ?

[fredmar]

Hi, I am looking for a Bluetooth Low Energy Soc based solution like nRF51822, but I'd like to have an open source firmware solution...

Do you have that kind of solution, nRF51822 solution or another ? (BLE and open source firmware)

[John]

This question is purely curiosity on my part: What drives the desire for an open source solution over a closed solution? I don't see a product requirement that would drive it so I can speculate that it is either a) You or your employer want/need to be able to control the source yourselves; b) A strongly held belief that all software should be open source

[fredmar]

a) It is for a project where everything is open hardware & open software (bitcoin harware wallet) b) We want to be able to make any kind of modification if needed c) I don't think every software should be open source, it is a choice people can make

[Petter Myhre]

We do not, but we are evaluating different options to make it possible.

There is an open source BLE stack implementation targeting the nRF51822 chip. You can found it in the following link: github.com/.../blessed.

Of course the s110 softdevice has a lot more features, but this stack can advertise, scan and we are implementing LL connections.

Just found NimBLE part of mynewt

• mynewt.apache.org/.../
• github.com/.../nimble

I'm guessing it could be easily ported to other OS
