Programmer v2.3.1

[DPJONES]

Hi 

This is the first time I have tried to use the nrf52840 dongle and  the programmer v2.3.1, it can see the dongle( com10), but as soon as I select Device tis is the response I get from the log?

11:53:01.172

Using @nordicsemiconductor/nrf-device-lib-js to communicate with target via USB SDFU protocol

11:53:02.277

Error when fetching device versions: readFwInfo error

Can Anyone help please

Regards

David

Since the development kit works fine, I guess that's not the issue. The reason for these errors is the Programmer app and nRFConnect app aren't compatible. This should be covered in steps 3-5 if you want to test this (outdated) workaround anyway. 

One thing you can try, so that we can isolate this issue to either the nRFConnect app itself or not, is if you use the nRFCommand line tools and write nrfjprog --eraseall or similar when the Dongle is connected to your computer and see what the response is.

Best regards,

Hi Simon

I have used the command line tool please see attached.

We really need to get to the bottom of this as we have brought a few to test, with the view of changing existing BLE suppliers to Nordic.

Kind Regards
