Custom toolbox application for DFU

[Hemabas]

Hi, I have developed one custom application and enabled DFU features in it. 

With the help of nRF Toolbox mobile application, I am changing the application code.

Now I am trying to develop one custom toolbox application either in PC or Mobile.

Initially I tried to connect with nRF52832 from bluetooth feature in laptop. I connected the device (contains nRF52832) with debugger.

 The device (contains nRF52832) is connected to the laptop (ensured with the help of debugger), but in laptop it is shown as trying to connect.

Is it possible to connect the device (contains nRF52832) with laptop?

Thanks.

If you connect a nRF5 Development Kit or dongle to the PC, you can use that to perform DFU over BLE with the target device, using nrfutil or nRF Connect BLE app.

Hi sigurd,

Thanks for your reply.

I connected dongle to PC and tried to perform dfu, but "board not found" error is occured as in attached image.

Now how to proceed?

What dongle are you using ? the nRF52840 dongle ?

Did you flash the dongle with the connectivity firmware?

What command did you use when you got "board not found" ?
