You need to provide a bootloader settings file also.

The entire procedure is documented here.

Thank you for your response. I read the post which you shared. So basically I will have to mergehex all files and then create a package and do OTA.

The command used for merging will be as follows:-

mergehex --merge s140_nrf52_7.2.0_softdevice.hex ble300.hex nrf52840_xxaa_s140.hex --output out.hex

Here in the above command

bootloader file - nrf52840_xxaa_s140.hex

softdevice file - s140_nrf52_7.2.0_softdevice.hex

application file - ble300.hex

and the output after merging will be out.hex.

please correct me if I am wrong. Also do I have to change any settings of loaction or just merging will help?

This is discussed in this case.

Essentially, if you program the application without using the bootloader the bootloader won't know that there is a valid application there.

If you still can't get it to work after reading through the old case let me know, and I will do my best to help.
