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!

[GS2]

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

Thank you Håkon,

My concern is that will be I able to use pca10040 development board for all ble_hids_mouse, ble_hids_keyboard and ble_hids_media examples at the same time?

[Håkon Alseth]

Hi,

 

Yes, it is possible to add to the usb descriptors, but you will have to populate the below mentioned structures as well.

Note that in newer SDKs, all hids example has media buttons (consumer control).

 

Kind regards,

Håkon

Thank you Håkon again,

Please can you give me more detail information - what board and newer SDK to use [with links]:
nRF52833 Development Kit, 
nRF52840 Development Kit, or 
NRF52-DK - that will be good for all examples!

Hi,

 

If you want to test with nRF5 SDK, use the latest version, ie. v17.1.0.

If you want to use NCS (zephyr based), use v2.6.1.

 

Both has HID-over-GATT bluetooth samples.

 

Kind regards,

Håkon

Thanks,

Please can you give me more detail information - what board to use  [with links]:
nRF52833 Development Kit, 
nRF52840 Development Kit, or 
NRF52-DK - that will be good for all examples!

What is the difference nRF5 SDK and NCS ?

You can use any board you'd like. nRF52840 has the most amount of flash and ram.

nRF5 SDK is for nRF52-series devices, and NCS is for newer devices.

NCS is future proof if you plan to develop on nRF53-series or newer devices.

 

Kind regards,
