DFU over BLE through nrfutil

[Vardhan Bhargava]

I am working on windows xp command prompt and using nrfutil version 3.5.1

I want to do a Device Firmware Upgrade over BLE through my nRF52 DK board on a custom element.

I have done it through nRF Connect, but now i need to do it using nrfutil

Its a PCA10040 board.

I have tried flashing the device with the connectivity firmware as well with both the baud rates 1m and 115k.

Hi ,

 

Could you describe your set up ? Which board do you want to update the firmware and which board do you connect to PC to be used with nrfutil.

 

Note that nRFutil requires a backend hardware to talk BLE. You would need a DK board flashing with a softdevice and the connectivity firmware \examples\connectivity\ble_connectivity, connect to PC to be able to use nrfutil  to do DFU.

I am using a nRF52 DK board connected to my PC.

I have another bluetooth device whose firmware needs to be updated.

I have a bootloader and an application .zip file i want to upload to my device connected through BLE to the DK board.

and yes i have tried flashing my nRF52 DK with the connectivity firmware.

Hi could you try to erase the chip and then call this:

nrfutil.exe dfu ble -ic NRF52 -n "YOURDEVICENAME" -pkg yourpackage.zip  -f

 

This will flash the connectivity firmware that supposed to work with nRFUtil. In v3.5.1 we still use S132 v3.0

 

If the issue persist, please try to downgrade the Segger Jlink driver to version 6.16c

Yes, it is working now.

Thank you!
