suntopbd 3:7036de769c32 24 * This program implements a complete HID-over-Gatt Profile:
suntopbd 3:7036de769c32 25 * - HID is provided by MouseService

suntopbd 3:7036de769c32 27 * - Device Information Service
suntopbd 3:7036de769c32 28 *
suntopbd 3:7036de769c32 29 * Complete strings can be sent over BLE using printf. Please note, however, than a 12char string
suntopbd 3:7036de769c32 30 * will take about 500ms to transmit, principally because of the limited notification rate in BLE.
suntopbd 3:7036de769c32 31 * KeyboardService uses a circular buffer to store the strings to send, and calls to putc will fail
suntopbd 3:7036de769c32 32 * once this buffer is full. This will result in partial strings being sent to the client.
