Dfu download error with Sofdevice 110 V8.0.0

[Amund Glomsås]

Since we have some performance problems with sd110 V7.0.0, we tried a upgrade to v8.0.0. This version(8.0.0) with IC revision 3 solved our performance problems:). But a new problem arise with the boot-loader: Remote DFU error: REMOTE DFU OPERATION FAILED with with nRF Master Control Panel on a Android. This happens with a FW image build with IAR. Images who folow with V8.0.0 in "examples/dfu/ble_dfu_send_hex/test_images_update" works. This worked with SD110 rel7.0.0 and nRF51_SDK_7.1.0 I get the same result with a DFU boot-loader built with both Keil and IAR. I dont think this is the same promlem as this, since this worked at last for me. Did some have some experience or comments for this?

Hi Amund, your .dat file contains: ff ff ff ff ff ff ff ff 01 00 5a 00 3f 26

I think 005A is the config ID for S110 V7.1.0. Try 0064, in other words: ff ff ff ff ff ff ff ff 01 00 64 00 xx xx
