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 | 26 | * - Battery Service |
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. |
