Device Firmware Upgrade using BLE not working

[asma]

Hello Everyone ,

I want to do application update over the air using BLE. I am using PCA100028 DK, SDK 7.2.0 and softdevice s110 7.1.0 . I am using the method given on this link developer.nordicsemi.com/.../a00066.html

In step 3 it is given to enable notification by writing 0100 i cant see anything on the DFU contol point charcteristic to write 0100 . i enabled the notification by clicking 3 downward arrows. then i followed step 4. the connection is lost with "GATT Error" and not with 'SERVER: Received Link Loss' and nothing sort of happening further i.e it is not advertising as "DFU Targ" . Is there anything i am missing .

Thanks & Regards

Asma
