choosing soft device

[Matej]

Hi,

I have a question about choosing "correct" soft device. I need only peripheral connection, but I'm bit in doubt for choosing SD110, because compatible sdk ver 10.0.0 (compatibility matrix) is already two years old. developer.nordicsemi.com/.../

For now i was using sd130 because I need peripheral and central connections at the same time... But within new project i need only peripheral...

So should I stay at the sd130 and just set number of central connection to zero, or switch to smaller softdevice which supports only peripheral connections. But sdk not offers so much as latest for sd130....

Thank you for info

I would just go with newest S130 available. However, S130 eats a bit more ROM memory than S110, so if there is a situation where you are out of ROM, you may think of using old S110... However i would not recommend that, as older SDK is quite incompatible with new one.

[Matej]

maybe would be great to also have noted such things... so can we say that sd110 is obsolete?

@matej: I agree with Wojtek, stay with the S130 and the latest SDK as long as you're not running out of flash and/or RAM.
