6KRO protocol

[huaminhtuan]

Hi everyone,

Currently, my team is developing a BLE keyboard which uses 6KRO protocol. Are there any examples for the 6KRO protocol using nRF52 chips?

Thanks!

Hi

The standard HID keyboard descriptor (also called the boot descriptor) supports 6 keys, which is the minimum required for a HID keyboard.

The ble_app_hids_keyboard example in the SDK uses this descriptor, so you can use that as a starting point if you want to support up to 6 keys.

Best regards
