I&#39;ve been messing around with nRFgo Studio for generating the setup data, and I&#39;ve noticed that the services.h file has the following line: #include &quot;aci.h&quot; I am unableen-USTelligent Community 13Mon, 02 Jun 2014 12:17:56 GMThttps://devzone.nordicsemi.com/thread/10472?ContentTypeID=1Mon, 02 Jun 2014 12:17:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f90066bf-8e55-4306-85a4-d29980d313f0David Edwin<p>The are already ports to 16bit PICs and it should port without any problems. aci.h and lib_aci.h are part of the nRF8001 SDK.
