Thank you,

Because you can not help me to create HID report descriptor for both mouse and keyboard with media keys you can close the case.

Thanks again.

Yes, the ble_app_hids samples work with windows, including 11.

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

void HIDSAPP_Init(void) {

result = HIDS_Update_Char(REPORT_MAP_CHAR_UUID, 0, 0,
MOUSE_REPORT_SIZE,

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

Kind regards,

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?

Hi,

[quote user="GS2"]AFTER ble connection was made[/quote]

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

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 !

Hi,

Did you follow what is stated here?

[quote user="hkn"]

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

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?

GS2 — Thu, 05 Sep 2024 21:20:05 GMT

Thank you,

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

Will it be better maintained in the future?

Håkon Alseth — Thu, 05 Sep 2024 10:31:42 GMT

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:

GS2 — Wed, 04 Sep 2024 17:00:43 GMT

I think it is different.

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

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

Håkon Alseth — Wed, 04 Sep 2024 08:06:37 GMT

Hi,

Could this be the issue that you are seeing?

nRF5 SDK 17.1.0 examples is not compiling in latest SES (6.20a)

If you get a compiler error, it is easier to help if you share the log.

Kind regards,

Håkon

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

GS2 — Mon, 02 Sep 2024 23:58:40 GMT

Was not able to compile any of the examples , even blinky!, with nRF5 SDK - the latest version v17.1.0. and with SEGGER Embedded Studio (SES).

Hi,

[quote user="GS2"]Can you please provide the link to HID-over-GATT Bluetooth samples?![/quote]

They are located in the SDK_PATH/examples/ble_peripheral/ble_app_hids_*

Thank you,

I am planning to use NRF52-DK with nRF52832 and with nRF5 SDK, use the latest version v17.1.0.

Can you please provide the link to HID-over-GATT Bluetooth samples?!

Hi,

[quote user="GS2"]Please can you give me more detail information - what board to use[/quote]

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

[quote user="GS2"]

What is the difference nRF5 SDK and NCS ?

[/quote]

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,

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!

Håkon Alseth — Wed, 28 Aug 2024 13:36:01 GMT

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,

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).

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 — Tue, 27 Aug 2024 08:39:56 GMT

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.
