HID and HRS profiles in one device

[Robert]

Hello, i would like to use HRM, HID, BAS and DIS profiles simultaniously. I used HID mouse example. I append required HRM things and it work almost properly. Problem is fault during storing CCCD information in HID_evt. err_code = ble_bondmngr_sys_attr_store(); The function returned error 11(Invalid Data). I suppose that is related to: BLE_BONDMNGR_CCCD_COUNT 5 BLE_BONDMNGR_MAX_BONDED_CENTRALS 2

...when I was changing this values function also return error(12 or 11). CCCD count set as 5 working fine(another combination occurs error during bonding initialization ).How to calculate this value properly?

Hi Robert,

This is the CCCD; developer.bluetooth.org/.../DescriptorViewer.aspx

You can count the number of CCCDs by checking how many of your services uses notification or indication. You can also see on bluetooth developer site which characteristic within a service is required/optional to have notification or indication. In your case, I believe you may have to do a erase of the pages used by the bondmanager, as Keil usually only erases the pages used directly by the application (check "Erase Full Chip" under debugger settings in Keil).
