Hi,Hung Bui:

I was amazing: What is the deference between boot mode and report mode?When in report mode ,it can't reach the function "ble_hids_boot_mouse_inp_rep_send()" ,It only can reach the fuction "ble_hids_inp_rep_send()" instead.

No, it's not dependent upon the resolution of the screen. But Windows may scale it up by using mouse-acceleration.

If you want absolute position, you may want to look for "mouse absolute position" on internet, there should be a solution on how to configure HID report of the mouse for that.

So, is the x and y delta values dependent upon the resolution of the screen!?

The function is very simple mouse_movement_send(int16_t x_delta, int16_t y_delta) . You provide x_delta, y_delta and you call the function, the mouse will move to the left x pixel on the horizontal and up y pixel vertically. If you use negative value, you will move in opposite direction.

I'm not sure what else you are asking for.

Hung Bui -- I get the mouse pointer moving to 4diff places on click of these buttons but that necessarily doesn't give me a detailed view of this function!

What do you see when you follow this instruction and you press the button ?

thank you! can you show me an example how can I move the pointer around the screen using this function!? I ran a for loop and put the gradually incrementing variable to no avail! couldn't move the pointer!?

mouse_movement_send only sends mouse movement. You need to look into the code of the function where we call ble_hids_boot_mouse_inp_rep_send(). x_delta and y_delta is the number of horizontal and vertical pixel from the current position of the mouse that the mouse need to move.

Hi Hung, how are you doing!? I'm using nrF5x SDK 11.

also, I wanted some documentation on this>> mouse_movement_send(int16_t x_delta, int16_t y_delta) functions functionality:

Which SDK version are you using ? Please have a look at the ble_hids_boot_mouse_inp_rep_send() function, to set a button to be pressed, you set button value to :

0x00 - No buttons pressed

0x01 - Left button pressed

0x02 - Right button pressed

0x03 - Both left and right button pressed

Note that after you press a button, you should release it.
