However you forgot to change the DEVICE_MANAGER_APP_CONTEXT_SIZE to match with your need ( should be =16 as in our ble_app_hrs_dfu example). This resulted dm_application_context_get return FEATURE_NOT_ENABLED and then cause your trip to reset.</p> <p>When you want to debug you should avoid letting the chip restart when issue occurs. You should add DEBUG in the pre-processor define. And add a break point in app_error_handler() in app_error.c to find the error code, line and file name that cause the error.</p><div style="clear:both;"></div>
