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

Hello Hung sorry for the mistake...those images were of ,when i tried with bootloader . the other problem is i didnt find any zip file in 7.1.0 nrf examples but only it is found in 8.0.0. nrf examples . as i am trying with 7.1.0 softdevice and 7.1.0 SDK i am using the method given in this link developer.nordicsemi.com/.../a00066.html

it is not working beyond step 4 i.e it is not advertising as DFU Targ after writing to the control point characteristic instead it is advertising as Nordic HRM only . I have updated the log again please check it once . One more thing if u follow the above link for 7.1.0 there is no where mention about flashing bootloader. so i have to flash bootloader or not.

Thanks & Regards Asma
