I try to use the FRDM-KW41Z with the BLE OTAP client example and configure it to use the internal Flash for temporary storing the image sent over the air (Kinetis Thread Stack Over-the-Air (OTA) Firmware Update User’s Guide, Chapter 3 Software implementation) and  (BLEApplicationDevelopersGuide, Chapter11.7.2 The OTAP Client) . I can connect to the OTAP client using the IoT Toolbox. But when I start the upload the uploading stops at 9% and restart at 0% for several cycles. What can I do to get the OTAP client work with this configuration?
