but not able to combine mouse with media and all 3 together!

    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

    Thank you,

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

    Will it be better maintained in the future?

    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?

    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

    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 !
