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;

I think it is different.

I have only SEGGER_RTT_printf.c and it's removal gies same error

[Håkon Alseth]

Hi,

 

Thank you for sharing the detailed log.

I believe that this is the issue that you're seeing:

 Build error 

 

Could you try the workaround posted here to see if this helps?

 

This effectively stems from alignment of sections that were done differently on the SES version that was available when nRF5 SDK v17.1 was released:

 RE: Bug in flash_placement.xml example file? 

 

Kind regards,

Håkon

[GS2]

Thank you,

Yes, I remove 0x4 attribute and it compiled without errors! 

Will it be better maintained in the future?

[GS2]

Thank you Håkon Alseth for support.

But now I have very impotent for me question:

I have implemented ble HID Keyboard, Mouse and their Combo on STM32WB55 hardware.

1. Now I have used HID Keyboard Report Descriptor from ble_app_hids_keyboard_pca10040_s132 project and used it in STM32 project. After making BLE connection device was installed without error.

2. But after using HID Mouse Report Descriptor from ble_app_hids_mouse_pca10040_s132 project the same way in STM32 -  after making BLE connection device was installed with driver error.

The question is: as BLE HID descriptor is not dependent on hardware - so how this can happens?

Did anybody try ble_app_hids_mouse_pca10040_s132 project? 

[Håkon Alseth]

Hi,

 

Did you follow what is stated here?

Håkon Alseth said:

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.

When adding new addition to the descriptor, this must be handled accordingly.

 

Kind regards,

Håkon

[GS2]

Thank you,

Yes, I understand that p_input_report and p_output_report should be mapped to HID report descriptor AFTER ble connection was made and drivers were installed based on HID report descriptor that was send first.

So when I send only HID report descriptor there is driver error during driver installation and I did not send any p_input_report and p_output_report !

 

[Håkon Alseth]

Hi,

 

GS2 said:

AFTER ble connection was made

GATT must be populated prior to the connection being made.

 

Please share your code so I can see what you've done. Specifically the ble_hids_init() function and your changes made to that function.

 

Kind regards,

Håkon

[GS2]

After establishing connection I send report descriptor:

void HIDSAPP_Init(void) {
tBleStatus result = BLE_STATUS_INVALID_PARAMS;

result = HIDS_Update_Char(REPORT_MAP_CHAR_UUID, 0, 0,
MOUSE_REPORT_SIZE,
(uint8_t *)&report_mouse);

that should initializes PC drivers installation and only after that by pressing buttons - different reports are send.

And again - Did anybody try ble_app_hids_mouse_pca10040_s132 example with Windows 11 Pro that I am using?

MOUSE_REPORT_SIZE,

This is not code from the ble_apps_hids samples. Where did you get this from?
