電腦：你是藍牙鍵盤嗎? ESP32：是的!我是藍牙鍵盤。 電腦：開始傳送鍵盤資料。 ESP32：OK!

設定步驟

1. ESP模擬藍牙鍵盤
2. 電腦新增藍牙鍵盤，連線ESP32
3. 電腦與ESP32連線成功，ESP32開始傳送鍵盤資料

microBlock程式

藍牙鍵盤名為為ESP32 BLE Keyborad

按下A鍵傳送PAGE UP，如果按下B鍵傳送PAGE DOWN

MicroPython程式

from micropython import const
import struct
import bluetooth
from ble_hid_test import BLE_HID
from button import Button
from time import sleep

keypad = BLE_HID('ESP_BLE_Keypad',16)
while True:
  if Button(5).wait_input():
    keypad.customized(0,75)
    print('DgUP')
  if Button(36).wait_input():
    keypad.customized(0,78)
    print('DgDown')
  sleep(0.1)
