Implementation of Middle click in BLE hid mouse

[Yadhu KP]

Hello,

I would like to know how to implement middle button click in hid mouse, by middle button click i am referring to scroll wheel click and  the function associated with it. i am using a nrf5 sdk 15.3. we already implemented left click, right click and scrolling options.

usually when we use middle click in a browser these kind of up and down panning option appears, basically im asking a function to implement this feature in hid mouse.

 the answer i was looking for was,  

uint8_t buffer[3];

buffer[0] = x; 
buffer[1] = y; 
buffer[2] = z; 

ble_hids_inp_rep_send(&m_hids,INPUT_REP_BUTTONS_INDEX, INPUT_REP_BUTTONS_LEN, buffer,m_conn_handle);

in this 

x=1,y=0,z=0 -> left click

x=2,y=0,z=0 -> right click

x=4,y=0,z=0 -> middle click 

NOTE: THIS IS HID MOUSE
