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

Sorry, the Dongle will need to be connected via a debugger (the one on the DK for example in order to communicate with the command line since it doesn't have a debugger onboard.

Either way since it's a problem with multiple Dongles I would think this is on the computer/nRFConnect app side rather than with the Dongles. Are you using a USB hub or do you connect the Dongles directly to the computer? We've also had some reports with issues when connecting to USB hubs.

Do you by chance have another computer available that you could use with nRFConnect and try to connect to?

Best regards,

Simon

Hi Simon

Sorry I don't understand how to connect via the debugger could you please explain in more detail as this is the first time we have have used Nordic.

I have tried connection to the hubs and also directly to the computer. 

Regarding computers the one we have been using is the main  R&D tool in the office we have many other compilers and emulators by other Manufactures already working on it without incident.

I suspect the problem lies with the device driver and nrf Connect.

Kind Regards
