hi....

How you zipped files application.hex and application.dat, while uploading am getting an error manifest.json file is missing. I am using example ble_app_hrs_with_dfu example from SDK 7.2.0 and softdevice s110 v7.1.0

Hi OlehSky

I have verified that the bootloader update works with nRF Toolbox v1.5 for IOS. I have followed the guidance given in the document "How to generate the INIT file for the DFU" that I have linked to earlier to create the CRC for the .dat file. I have created two files, bootloader.bin and bootloader.dat and put them both into a zip file. Then with nRF Toolbox I have uploaded the zip file to the device. Let me know of any complications.

Have you seen the document titled "How to generate the INIT file for the DFU"? I can't remember exactly where I found it.

It specifies that you need to remove 2 lines in the HEX file before you generate the BIN.

:02041000EA 
:041014000C0030015

then generate the CRC for the BIN like normal. After that replace the lines in the hex file.

Thanks, Jeremy

Hi Stefan, yes I'm aware of this thread, in my case the 'application.dat' worked, but the 'bootloader.dat' didnt. the CRC done in the same way as for the app: hex2bin then crc - invert for endianless ;) THis works with application firmware update but not for the bootloader itself. I'm using iOS devices to test.

Try to follow the guide given in the update from 2.1.2015 on this thread.
