Custom HID

Hi,

I'm trying to build a custom HID device. I'm not able to receive any bytes on the host machine (I'm using an HID API). The Nordic board connects to the bluetooth of the computer, but fails to send any data.

Some numbers are displayed when I press SetReport & GetReport buttons.

When I press a button, I can see change in values as per the logic in the event handler.

So is anything missing here?

Hey,

Have you made any modifications to the HID example code?

If you try to run the unmodified example, do you receive any data?

Nope its a keyboard example so I think Windows is not allowing a custom keyboard to send data for security reasons. So I implemented gamepad & I was able to receive the data.

I limited data to 8bits for testing purpose. There is no driver error so bluetooth connects just fine and I get similar results on HID API as pasted above. So is it actually sending data through report? I dont know if the code is working and how I should progress to make it work!

You should be able to run the keyboard example on most of the newer versions of Windows. If not then you should make sure it works before trying a custom application. What Windows version are you working with?
