Should I use S110, S120, S130, S210 or S310 ?

[Thomas]

I have bought the nRF51 dev kit. I can download all these soft devices. But what do they really correspond to ?

I think of them as library/apis for doing BLE development but why are there so many, which one should I use ?

Thanks

hello thomas.. its depends on application you need.. s110 will behave as a end node,s120 will acts as a central/hub,s130 will acts as both central and peripheral at the same time. s210 and s310 related to ant technology..

thanks! what if I want broadcaster/observer (I have 2 nRF51 DK boards)

Use S130 in case to be broadcaster/observer at same time, just you have to manage the flags at adv param structure which notify that the device will not connect!

Since you have 2 nRF51 DK, you can use one as a broadcaster(with S110), and the other as an observer(using S120).

Best.
