/**
 * This program implements a complete HID-over-Gatt Profile:
 *  - HID is provided by MouseService
 *  - Battery Service
 *  - Device Information Service
 *
 * Complete strings can be sent over BLE using printf. Please note, however, than a 12char string
 * will take about 500ms to transmit, principally because of the limited notification rate in BLE.
 * KeyboardService uses a circular buffer to store the strings to send, and calls to putc will fail
 * once this buffer is full. This will result in partial strings being sent to the client.
