I want to implement a BLE composite device with BLE UART and BLE HID, and both services can work at the same time.

Hello! I want to make a Bluetooth game controller, and the functions of the controller buttons can be modified by the host computer application on Windows. The host computer notifies the "new functions" of the game controller buttons through Bluetooth serial communication.

I need BLE to implement two services, UART and HID, and both can work at the same time.

Do you have any routines that include two BLE services for reference? Preferably from NCS.

Hi fuyinyuezhang,

As you are setting your goal to have both Nordic UART Service (NUS) and HIDS work at the same time, please be aware that HIDS can only be handled by the peer OS, and not by your third party app.

With that in mind, it should be possible to have HIDS controlled by the OS, and NUS controlled by your application.

The Bluetooth: Peripheral HIDs sample shows how to provide HIDS, Battery Service, and Device Information Service at the same time (which is required by the HID over GATT Profile specification). This shows you how to enable HIDS and other Services.

For enabling and using NUS, please refer to the Bluetooth: Peripheral UART sample.
