This contains projects that should work with the S130. main.c is equal, it is just a predefine (Options for Target-&gt;C/C++-&gt;Preprocessor Symbols-&gt;Define) that is different, S110/S130. Remember also that their flash and RAM usage is varies.</p> <p>You can search for S130 in the S110 and S120 examples to find where the predefine is used and what is handled differently between the SoftDevices.</p><div style="clear:both;"></div>RE: how can we set a device to act as master and slave in blehttps://devzone.nordicsemi.com/thread/26553?ContentTypeID=1Sat, 06 Jun 2015 19:44:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fbdd1750-03ec-49c5-9f50-38ea635171edSusheel Nuguru<p>USE S130 for your bridge side which can act both as central and a peripheral. There are examples for it in SDK8.1</p><div style="clear:both;"></div>
