We wrote the prototype application firmware for a BLE HID Controller. The idea was to build a simple HID device with bare minimum keys. By leveraging the simple HID keyboard example provided in the SDK we developed the application firmware to handle multiple keys as per USB HID Specification. A few combination of keys would then be configured by the user to serve as hot keys for a complex desktop software like photoshop.
