Hello,

Sorry, we don't have any examples/demos displaying a HID Touchpad. We do have an example using a mouse. Have you compared this to the ble_app_hids_keyboard example? You need to find out how to initialize and send the HID reports for a touchpad. I didn't really find much information on touch pads in the USB HID usage tables documentation. The BLE is only a layer on top of this carrying the HID tables from the nRF to the computer.

Perhaps the ble_app_hids_mouse example is a better place to start. It already shows how to move the mouse and click.

Hello,

I am sorry, but the HID protocol is a bit complex, and I am not sure I understand what you mean. What did you try to add when you got the zero value for feature reports? Shouldn't you call something similar to send_key_scan_press_release() if you want to imitate a touchpad?

Did you try to add ble_hids_feat_rep_set()? What does it return?

Remember that the github that you link to is not made by us, so I am not familiar with it.
