weisimin 0:706cf6936c11 26 * This program implements a complete HID-over-Gatt Profile:
weisimin 0:706cf6936c11 27 * - HID is provided by KeyboardService
weisimin 0:706cf6936c11 28 * - Battery Service
weisimin 0:706cf6936c11 29 * - Device Information Service
weisimin 0:706cf6936c11 30 *
weisimin 0:706cf6936c11 31 * Complete strings can be sent over BLE using printf. Please note, however, than a 12char string
weisimin 0:706cf6936c11 32 * will take about 500ms to transmit, principally because of the limited notification rate in BLE.
weisimin 0:706cf6936c11 33 * KeyboardService uses a circular buffer to store the strings to send, and calls to putc will fail
weisimin 0:706cf6936c11 34 * once this buffer is full. This will result in partial strings being sent to the client.
