https://devzone.nordicsemi.com/f/nordic-q-a/35427/app-crashes-when-using-bonds-on-sdk-15Hi, I&#39;m having a problem with the use of bonds since I migrated from SDK 13.1 to 15.0. The problem is that the function gscm_local_db_cache_update() in the gatts_cache_manager returns NRF_ERROR_DATA_SIZE. I didn&#39;t have that problem at all in SDK 15en-USTelligent Community 13Tue, 19 Jun 2018 09:21:34 GMThttps://devzone.nordicsemi.com/thread/136698?ContentTypeID=1Tue, 19 Jun 2018 09:21:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:026c829b-8085-4f92-acc3-a3c04b0e41abAndy<p>Hi H&aring;vard, that indeed immediately fix the problem!
