Need help with combining mouse, keyboard and media into one HID.

[GS2]

Hello,
I have combine mouse with keyboard HID_12 and keyboard with media HID_23,
but not able to combine mouse with media and all 3 together!
Here are my HID_12  and HID_23:

Thank you Håkon,

1. I am using BLE_HID_selfie for keyboard and media and BLE_HID for mouse and keyboard.

2. How to send all STM32wb55 my project to you?

3. Not sure.

4. After connecting to Bluetooth - after few second - it said - driver error!

Thank you Håkon,

3. Yes The HID over GATT profile for Bluetooth USB HID specification

I am going to use BL651, nrf52810, pca10040 development board with nRF5 SDK v14.1.0 for BLE - nRF desktop application. HID for usb do not depend on SDK or device. Here are reports for given mouse, keyboard and media report descriptors I am using: Can you help?

typedef struct

{

uint8_t ReportID;

uint8_t buttons;

int8_t x;

int8_t y;

int8_t wheel;

} mouse_report_t;

//#ifdef ST_SELFIE

/* Keybaord key data*/

typedef struct

{

uint8_t ReportID;

uint8_t Data_0;

uint8_t Data_1;

uint8_t Data_2;

uint8_t Data_3;

uint8_t Data_4;

uint8_t Data_5;

uint8_t Data_6;

uint8_t Data_7;

} keyboard_report_t;

/* Multimedia key data*/

typedef struct

{

uint8_t ReportID;

uint8_t Data_0;

uint8_t Data_1;

uint8_t Data_2;

uint8_t Data_3;

} multimedia_report_t;

Hi,

 

Based on your description, it is not easy to map which example specifically you are using in SDK v14.1, so I will assume one of the basic ones in the SDK.

If you take one of the ble_app_hids samples, lets say ble_app_hids_mouse, there is a main.c::hids_init function that maps each report to a given HID over GATT input, output, or feature report.

Each new descriptor that you add will need to be mapped to the corresponding p_input_report[index] (or p_output_report) to ensure that it is populated in the GATT database.

 

When you have any issues, please provide any log output from the nrf side and a detailed description on what occurs on the central side.

 

Kind regards,

Håkon
