Thank you.

Here are the known samples you can refer to for each need:

1. BLE / no Dongle - bluetooth - HID

Bluetooth: Peripheral HIDS keyboard
Bluetooth: Peripheral HIDS mouse
nRF Desktop
- This is a complete application that has a pretty high learning curve to understand.

2. Custom 2.4GHz / Dongle - HID

There is no sample that showcases this. You will need to combine the ESB samples with USB HID sample.

The mouse and keyboard will be one of the two ESB devices. The dongle device will support both ESB and USB HID. It receives input data from the mouse/keyboard device and then sends to the connected computer via USB.

ESB samples can be found here: Enhanced ShockBurst samples

3. HID feature / USB - HID

I hope this is clear now.

I am trying to reproduce 2.4G Wireless & Bluetooh & USB Wired Mechanical keyboard on a market now,

using nRF5340 module. And for this I need 3 examples to start working on it.

1. BLE / no Dongle - bluetooth - HID

2. Custom 2.4GHz / Dongle - HID

3. HID feature / USB - HID

Thank you, but I am still confused:

BLE / Dongle feature - Dongle is not needed!

Custom 2.4GHz / Dongle feature - is needed, but No sample!

Custom 2.4GHz - ESB samples - No dongle??

My apology for being unable to follow up. I have been on another assignment and don't really work on DevZone these days.

Mouse and keyboards are computer accessories. I was trying to use a different phrase to avoid repeating the same words.

You can think of it being roughly like this:

	BLE	Custom 2.4GHz	USB
Dongle feature	nRF Desktop	No sample	N/A
HID feature	nRF Desktop	No sample	USB HID Keyboard and USB HID Mouse samples
No dongle or HID feature	BLE samples	ESB samples	USB samples

What is computer accessory dongle product?

For: 2.4G Wireless & Bluetooh & USB Wired - only 2.4G Wireless & Bluetooh need dongle, USB Wired - do not!

My question was: do you have 3 separate samples for USB keyboard 1: 2.4G Wireless, 2: Bluetooth, 3: USB Wired all for nRF5340

Regarding this question from you:

[quote user="GS2"]

Do you have 3 examples for Connection Mode: 2.4G Wireless & Bluetooh & USB Wired

for the same nRF5340 module ? For mechanical Keyboard.

[/quote]

I understood it as asking about a sample that supports using both proprietary 2.4GHz Wireless and computer accessory dongle product. We don't have a sample that supports both of those. The Enhanced ShockBurst samples only show how to use ESB to communicate between two devices.

Please spend time reading the documentation I linked.

Yes.

Are they the same:

I don't think we have a custom 2.4G Wireless example, unfortunately

The nRF Desktop app I linked earlier demonstrates mechanical keyboard feature for Bluetooth and USB Wired. I don't think we have a custom 2.4G Wireless example, unfortunately

Verified Answer is one of the "Closed" state for a ticket. It's actually better than just "Closed," because "Verified Answer" means that at least a conclusion was reached.

Nevertheless, if that is what you wished, I will now make the ticket "Closed" as well.

RE: Wireless HID USB without Bluetooth

GS2 — Thu, 16 Jan 2025 16:45:00 GMT

The status of my ticket was not CLOSE - it was ~ Verified Answer.

Can you close this ticket or not?

How come - I can reopen the ticket, but am not allow to close my ticket??!!

Could you please describe what it looks like on your end, and what you expect? I will see what is wrong, and how it can be fixed.

HOW TO CLOSE THE TICKET???

RE: Wireless HID USB without Bluetooth

GS2 — Thu, 16 Jan 2025 02:06:43 GMT

Just to let you know:

The ticket Wireless HID USB without Bluetooth has been CLOSED.

IT IS NOT.

RE: Wireless HID USB without Bluetooth

Hieu — Wed, 15 Jan 2025 20:56:33 GMT

The log showed that the ticket was closed successfully. It was only reopened when you post this last message. 😅

Nonetheless, I will close it for you now.

RE: Wireless HID USB without Bluetooth

GS2 — Wed, 15 Jan 2025 16:16:23 GMT

Still not closed! Not user friendly interface!

Hieu — Wed, 15 Jan 2025 08:45:53 GMT

The ticket is automatically closed when an answer is verified. To verify an answer, on the answer, click on "More," then click "Verify Answer."

If you still have difficulty, I would be happy to close the ticket for you 🙂

How to close the ticket? I do not see any option!

Any comparisons have to be relative to the project need. Almost always, it involves balancing between performance, complexity, price.

Unfortunately, we don't go in depth with product selection on DevZone. Our Sales team will be able to provide better support with that if you need it.

GS2 — Tue, 07 Jan 2025 18:38:14 GMT

Thank you, seams nRF5340 is better.

[quote user="GS2"]1. Will it be possible to use Enhanced ShockBurst samples for (mouse and keyboard) dongle product?[/quote]

Yes

[quote user="GS2"]2. What will be the differences in using nRF5340 DK and nRF52840 DK ?[/quote]

They are for evaluation and development of different SoCs, the nRF5340 and nRF52840 respectively.

For an overview on the differences between the two SoCs, please refer to our Product Guide: Product-Guide_Nordic_2023.pdf

For more details, please refer to their product specifications (nRF5340, nRF52840).

[quote user="GS2"]3. Is there a tutorial on how to use these Enhanced ShockBurst samples ?[/quote]

All samples come with documentation. Simply click on each sample's link to see it.

The same documentation is also available in the README file in the sample source code, when you browse them in the SDK.

[quote user="GS2"]4. Why there always NRF24L01 and nRF21540 are mention with Enhanced ShockBurst ?[/quote]

The nRF24L01 is a very old product that supports only Enhanced ShockBurst (ESB).

The nRF21540 is a Front-end Module that improves a radio's TX and RX. I don't think it is always mentioned with ESB, but it can be used with ESB.
