How to setup a compostive device like mouse+keyboard in BLE application?

[jimlin]

Hi nordic engineers,

I want to add a mouse function in the keyboard application project, but have some questions to know:

1.Does BLE support such compositive device, like USB that? 2.If YES, how to merge the mouse and keyboard descriptor? Either of the two seperate demo project uses the single HID descriptor, and not find anything like the Interface in USB? If put both of the HID descriptor in the hids_init() simply, how does the ble_hids_init() work? Should I call the ble_hids_init() two times for each device?

And , if there is similar demo for reference?

Thanks all.

Hi Jimlin,

Sorry for the late response. Yes you can combine them together in one device. You just have to add the reports as with USB HID. We have an example where we combine mouse in keyboard in one HID device. It's the smart remote 2.

If you don't have access to the firmware, please create a case in our My Page support portal, and request an access.
