NRF52840 Dongle not detected

Hi.

[quote user="kian79"]When you mention that "It should appear as a composite device", I have the impression that when I plug in the dongle, it should emulate an external drive and I should see a new drive letter appearing on windows explorer. I guess it doesn't happen that way.[/quote]

I'm a bit unsure what you mean here, a "composite device" is a peripheral device which supports more than one device class.

Best regards,

Andreas

Hi Andreas,

Thank you. I know I need to press the reset button for the LED to blink in red. I can already program the dongle using nRF connect.

When you mention that "It should appear as a composite device", I have the impression that when I plug in the dongle, it should emulate an external drive and I should see a new drive letter appearing on windows explorer. I guess it doesn't happen that way.

Thanks.

Hi again.

You have to put it in bootloader mode, as shown in the documentation here.

Best regards,

Andreas

Hi Andreas,

When I plug in the dongle to the usb port of my computer, the status light (LD2) is not pulsing red. It does not appear as a USB drive on windows explorer.

From the computer's device manager I can see Nordic Semiconductor DFU-> nRF Connect DFU Trigger, and under Ports (COM&LPT) -> nRF Connect USB CDC ACM

I can detect the dongle from nRF Connect (v2.6.1) with both the Bluetooth Low Energy App (v2.2.0) and Programmer App (v1.0.1).

Cheers,

Kian

Hi.

I see you have created another ticket, so I will not answer in that. It should appear as a USB composite device after a few seconds. Does the status light (LD2) pulsate red?

Best regards,

Andreas

I deleted the Bluetooth Low Energy App on nRF Connect and reinstalled. Now I can detect the dongle on the Bluetooth Low Energy App. The dongle still doesn't appear as a USB drive. I am not sure if it is suppose to.

When the dongle is connected to my computer USB port, should it appear as a USB drive on windows explorer? Because, now it doesn't.

And its not working with nRF Connect Bluetooth Low Energy App. It doesn't detect the dongle.

Thanks AndreasF.

I figured out what is wrong. It was a stupid mistake. its my first time using nRF Connect. I was using Bluetooth Low Energy app to detect the dongle which is wrong.

I downloaded the Programmer app and now its working.

Hi.

The nRF52840 Dongle is in bootloader mode if the red led is blinking.

I suggest you take a look at the nRF52840 Dongle Programming Tutorial, just to get you started.

Best regards,

Andreas
