DFU cycle testing

[ms360]

Hi ! 

I have 5 different bootloaders for 5 pieces of hardware that I would like to cycle test OTA DFU with BLE. 
I have some questions

• Why does nrfutil dfu ble require a COM port? the DFU IOS app does not, seems strange, and also fails because I don't have a COM port connected. 
• What's the shortest path to script a BLE DFU from either
  • Mac M2
  • RPI 5
  • Windows 10 machine

The COM port thing is holding me up in mac/windows. 
The RPI5 lack of modern python support + non x86_64 is making this seemingly simple task in to a can of worms

This is what I'm trying to figure out.

So I took my pca10056 dev kit and flashed connectivity firmware on there. 
Then I got the dreaded No ping response after opening COM port. 
usbmodemFE813A68F73E1 is the native USB port of the pca10056. 

% nrfutil dfu ble -pkg V28.zip -ic NRF52 -p /dev/tty.usbmodemFE813A68F73E1  -n "devicename" -f    

Flashing connectivity firmware...

Hello,

Please note that the link you are referring to is based on an old version of the nRF Util tool (< v7.0.0), which is no longer compatible with newer versions. What version of nRF Util are you working with? (I should have asked this before.) I am using version 7.12.0, and the documentation I referenced also applies to newer versions.

When you check the dfu ble command, you will see that it requires a second nRF device connected to the PC, which acts as the BLE adapter.

Kind Regards,

Abhijith

I did figure out I need to use an nrf52 dongle. I'm on a pca10056 with connectivity firmware, plugged into the nrf USB port. Looks like we're running the same version.

Does that mean your confusion is over, or are you still confused or facing issues related to the main query? Please let me know if you are still struggling, and I can assist you further.

Kind regards,
