Problems using the DFU OTA - Last iOS update not working

[Ignacio Lopez]

Hi,

Through this post I got an updated bootloader for the nRF51822 128Kb chip version:

After the last update of the iOS nRF Toolboox Version 1.8, the bootloader is not working any more. Could you have a look at this?

Thanks

@Ignacio: I just tested here with nRFToolbox v1.8 (iOS v8.3) I managed to update the hrs_s110_7_0.hex (no init data) and the device started in HRM firmware normally. Could you double check and let me know what was the issue ? A sniffer trace of what happened over the air would be very useful.

Yesterday I tried several times and I couldn't get it to work. Today first time working. Thanks for your help Hung
