upload error while updating firmware via OTA using nrf connect application.

[kishor babu]

I am trying to update the firmware via OTA , while uploading the firmware I am getting "upload failed" message on the nrf connect application.

I am using nrf51422 board,sdk v10.0.0 .

I have downloaded the "dual_bank_ble_s110" boot loader firmware in the nrf51422 board.In nrf connect I have connected to "DfuTarg". 

I have created a zip file for "ble_hrs" example, so when I am trying to update the firmware from nrf connect I am getting "UPLOAD FAILED" message on the application.

Could anybody help me in solving this?

Thanks in advance.

Hi,

I will suggest you to first go through the documentation and see if everything is done correctly.

Hi,

Can you update nrfutil to the latest version and try again? It can be found here.

 updated the nrfutil but when I am trying to generate the zip file I am getting "Error: No such command "genpkg".

The other thing is when I loaded and connected to "ble_app_hrs with dfu" and trying to upload the dfu test image "dfu_test_app_hrm_s110 i, it is not happening showing the error "DFU_DEVICE_DISCONNECTED". 

I want to update dfu using sdk v10.0.0 only, so, how can I make it  to work?
