nRF51822 Difference between S120 and S110

[amine]

Hello,

Actually, I am evaluating the nRF51822 using the EK. I have some questions as follows:

1- Is the S120 an enhanced version of the S110, and what is the real difference between them? 2- Should we use privilege the S120 for future designs? 3- What about the availability of the 130 SoftDevice, can I use it for a WSN deployment? 4- How can I flash an off-board nRF51822 SoC?

Thank you !

S120 permits to set up a central, S110 permits to set up a peripheral.
