- * 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.
