Please tell me the scroll up/down command for mouse development.

[ParanBada]

I am developing a simple BLE mouse using ble_app_hids_mouse of SDK17.1.0.
I found out through devzone that left mouse button click sends (1, 0, 0) and right button click sends (2, 0, 0).
Of course, I need to send release data (0, 0, 0) in pairs.

report_map_data is:

/////// Mouse //////////////////////////////////////////////////////////////////

So far, it works fine.

However, I need to send additional scroll up and scroll down data, but I don't know how.

I searched the internet for a long time but couldn't find it.
I want to send the following data.
scroll up = ?
scroll down = ?
scroll left = (0, 0, 0x01)
scroll right = (0, 0, 0xFF)

If possible,
zoom in = ?
zoom out = ?

I don't know where to find this information. Thanks,

Best Regards,

YIM.

scroll up = (0, 0xFF, 0)
scroll down = (0, 0x01, 0)
scroll left = (0, 0, 0x01)
scroll right = (0, 0, 0xFF)

These values are right?

Hi,

Were you able to resolve this? If not, I recomend you download the old nRF ready desktop reference design and look at the report map there in source_code/pca20001_mouse/desktop_mouse/m_coms_btle_cfg.h (but do not use other parts of the SDK/code there as it is very old).
