How to send mouse right-click in nRFready Smart Remote

Question

I develop RF Remote Control with nRFready Smart Remote.

nRFready Smart Remote Feature:

Remote Control : nRF24LE1 (MCU + RF) -> Device
USB dongle : nRF24LU1+ (MCU + RF + USB) -> Host

I am trying to send mouse right-click event from Remote Control to USB dongle.

(1) Remote Control

I send a data through PIPE_TOUCH. The data format was defined in the Smart Remote Firmware documentation.

[ Total 7 Bytes ]

Finger 0 X delta : 1 Byte
Finger 0 Y delta : 1 Byte
Finger present Button/LED Status : 1 Byte
Gesture flags 0 : 1 Byte
Gesture flags 1 : 1 Byte
Scroll zone 1 : 1 Byte
Scroll zone 2 : 1 Byte

For exameple, it works well in case of mouse left-click event.

0 (X)

0 (Y)

1 (any) (Button/LED Status)

0x08 (Gesture flags 0)

0 (Gesture flags 1)

0 (Scroll zone 1)

0 (Scroll zone 2)

unsigned char TestMouseRF_nRF24LE1 (char s8X, char s8Y, unsigned char u8ButtonStatus, unsigned char u8Gesture0, unsigned char u8Gesture1) {

    unsigned char tx_buf[7];
    unsigned char i = 0;
    
    unsigned char u8Ret = 0;
    
    
    
    // (1) buffer zero
    for (i = 0; i < sizeof(tx_buf); i++)
    {
            tx_buf[i] = 0;
    }
    
    // (2) set value
    tx_buf[0] = s8X;
    tx_buf[1] = s8Y;
    tx_buf[2] = u8ButtonStatus;
    tx_buf[3] = u8Gesture0;
    tx_buf[4] = u8Gesture1;
    
    // (3) send
    u8Ret = gzll_tx_data(tx_buf, sizeof(tx_buf), PIPE_TOUCHPAD); 
    
    // (4) check and reset
    SetTxAttempted(1);
    g_u16UserActivityCount = 0; 
    
    return u8Ret;

}

But I have a problem to send mouse right-click event.

For example, mouse right-click

0 (X)

0 (Y)

1 (any) (Button/LED Status)

0x10 (Gesture flags 0)

0 (Gesture flags 1)

0 (Scroll zone 1)

0 (Scroll zone 2)

(2) USB dongle

Nordic example source "projects\nRFready_2_4_GHz_RF_Smart_Remote\dongle\main.c"

I could see repack_mouse_packet function.

It did not define about mouse right-click.

 enum TapType {Press     = BIT_5, 
              EarlyTap   = BIT_3, 
              DoubleTap  = BIT_2, 
              TapAndHold = BIT_1, 
              SingleTap  = BIT_0,
              NoTap      = 0};

I modified it.

 enum TapType {Press      = BIT_5, 
               RightTap   = BIT_4,
               EarlyTap   = BIT_3, 
               DoubleTap  = BIT_2, 
               TapAndHold = BIT_1, 
               SingleTap  = BIT_0,
               NoTap      = 0};
        
 (...)
 if (input_buffer[3] & EarlyTap)
 {
      mouse_btn = true;    
      button_packet[MOUSE_BUTTONS] = 0x01;
 }
 else if( input_buffer[3] & RightTap )
 {
      mouse_btn = true;
      button_packet[MOUSE_BUTTONS] = 0x02;
 }
 (...)

I downloaded and run but it did not work mouse right-click event.

I read USB HID Version 1.11 and 1.2.

I saw mouse Report Map(mouse_report_desc.h).

I have 2 problems.

First, I cannot find data format of mouse in Remote Control(Device).

Finger 0 X delta : 1 Byte
Finger 0 Y delta : 1 Byte
Finger present Button/LED Status : 1 Byte
Gesture flags 0 : 1 Byte
Gesture flags 1 : 1 Byte
Scroll zone 1 : 1 Byte
Scroll zone 2 : 1 Byte

Finger present Button/LED Status <== what does each bitmask mean?

Gesture flags 0, Gesture 1 <=== what does each bitmask mean?

Second, I cannot find data format of mouse in USB dongle(Host).

 enum TapType {Press     = BIT_5, 
              EarlyTap   = BIT_3, 
              DoubleTap  = BIT_2, 
              TapAndHold = BIT_1, 
              SingleTap  = BIT_0,
              NoTap

button_packet[MOUSE_BUTTONS] <=== what does each bitmask mean? why does not it define about mouse right-click?

USB HID 12v2, Button Page (0x09) (pg 67), Table 14. Button Usage Page

Button 1 : 1
Button 2 : 2

...

(...)

else if( input_buffer[3] & RightTap ) {

    mouse_btn = true;
    button_packet[MOUSE_BUTTONS] = 0x02;

}

(...)

Thanks in advance.
