We are not using sdk , we have soft device version s132_nrf52_5.0.0 , firmware version 4.1.10, i am using the latest version available on app store and ios version 12.3.1 iphone 6

But you must have an application firmware that adds the Buttonless DFU service to the GATT table of the SoftDevice using the SoftDevice API? Is it possible to run the application on a nRF52 DK? If yes, could you attach the compiled hex file to the question so that i can test it here?

1_1.99.3.hex

1_1.99.4.hex

Here the attached hex files for it

HI Vivek, 

after flashing the hex files to nRF52 DK and I connected to it with a Samsung Galaxy S9 using nRF Connect. I do not see the Nordic Buttonless DFU service with my Android device, just an unknown service. Are you sure that you have added this service?

Best regards

Bjørn
