https://devzone.nordicsemi.com/f/nordic-q-a/72321/switch-from-s210-to-s310Hi, Is switching from softdevice S210 to S310 as simple as changing the IRom start address and putting the uploading the softdevice onto the device? Now I have IROM1 start: 0xD000 and size: 0x33000. Should I change these values? To what?

One needs to also change the Ram settings.

I moved the address from 0xD000 to 0x1D000 as the S310 take up 0x1CFFF. The program loads and runs however the execution failes @ the softdevice initiation. To be exact, it fails @&nbsp;err_code = ant_plus_key_set(ANTPLUS_NETWORK_NUMBER);</p> <p>Network number i 0. Network key is set properly I suppose as the code worked on the S210.</p> <p>I also changed the settings in the preprocessor settings for C++ and Asm (changed S210 to S310). Need I change anything else?</p><div style="clear:both;"></div>
