https://devzone.nordicsemi.com/f/nordic-q-a/4917/problem-with-s120-v2-0-0Hello, I am trying to use the v2.0.0 of softdevice S120 released today. I copied the included header files in nRF51822/Include/s120/*.h and modified the Target -&gt; IROM1 to Start from 0x1D000 (116kB) with the size 0x22000.

But for now you can find api~.dox file which is a doxygen file. generate html documentation out of that file and find the relevant info, may be you will get some more info about s120v2. I have produced html files from api~...dox file and got a bit api and defines information regarding s120v2.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/17365?ContentTypeID=1Wed, 24 Dec 2014 13:41:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e4c8d0ff-9552-419e-ad34-9fa1d7ff1932Aditya Bansal<p>Hello Annim, yes, I replaced the s120 SoftDevice header files in my SDK&#39;s Include folder with the included S120 API header files.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/17366?ContentTypeID=1Wed, 24 Dec 2014 07:43:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:407faa48-c238-4fe4-a5d3-987d7b5f5e8cAnnim<p>Please replace the s120 v2 api files too, the include files you will find inside api folder in the same zip. with s120 v2, new api came. hope this would have helped you.</p> <p>Edit: i missed out reading you text, as you have already copied the files.</p><div style="clear:both;"></div>
