NRF24LU1P nAN-22-based HID device issue

[eugenePi]

Dear All,

I'm using NRF24LU1P USB dongle to emulate mouse and keyboard. I've taken nAN-22 firmware as HID example and modified code to behave as 2xHID composite device.

What I did is that I set up two interfaces each with IN interrupt endpoints 81 and 82, and boot protocols 1 and 2 according to HID standard, and added all necessary descriptors.

After I flash my dongle, device enumerates successfully as 2xHID mouse+KB and USBView shows me that all descriptors and endpoints were setup correctly.

But I don't see any periodic data reports sent to PC nor from mouse and keyboard.

I digged down to code and made some debugging. Figured out that USB Endpoint Callbacks, e.g. ep_1_in_cb, are never called.

I expected to send HID report data inside them. Moreover, in USB HAL, the vector ivec in USB_ISR never has e.g. INT_EP1IN and respective callback is never called.

It only has value of INT_SUDAV.

So actually IN endpoint periodic communication is missing.

Am I doing something wrong?

Hi Eugene,

 

Am I doing something wrong?

Could be. Could you share your changes, so I can try it out?

 

Kind regards,

Hi Håkon,

Yes, of course ) Please find attached the modified project. It should compile without any additional files.

Hi,

 

Thanks for the code. There's a couple of things that were missing, for instance the direction of the IN data you're sending (should be hal_usb_send_data(0x80 | EP, ...)).

The reason why your EP callbacks are not running is due to the printf taking too long. I commented it out and now it runs as it should.

I also count 4 bytes in your mouse descriptor, while in your application it is set to 3 (buttons + X + Y + wheel = 4 bytes).

 

Seems to be working fine now:

 

Here's the edited .zip: nod_edit_nAN-22_v1.1.zip

Hopefully I haven't changed that much of your project settings.

 

Kind regards,

Håkon

Hi Håkon,

Thanks a lot for helpful modifications, indeed I missed some important things! 

After trying out modified project, and installing correct drivers, I finally got it working as needed )

As my goal is to finally make a wireless device, I've noticed the nRFReady Desktop solution that seems to implement the

RF connection nRF5x<->nRF24 and pairing for such devices as combo keyboard/mouse.

What about its license, does it allow to use it in mass production for commercial use?

Does it include demo boards, or is it just a firmware/library pack?

Best regards,

Eugene
