玩转 BLE 调试！这份超详细指南请收好～

各位热衷于探索科技世界的小伙伴们今天要给大家分享一份超厉害的 BLE 调试文档哦它就像一把神奇钥匙能让你的智能设备像亲密好友一样顺畅 “聊天”不管你正捣鼓着智能手环、智能灯泡还是酷炫的智能门锁有了这份指南BLE 调试对你来说简直就是小菜一碟赶紧跟着我来一探究竟吧超酷的 BLE 闪亮登场BLE 呢其实就是低功耗蓝牙Bluetooth Low Energy的超萌简称蓝牙本身就是一种超棒的近距离无线通信技术在 2.4GHz 这个免费频段上欢快地 “奔跑”现在已经在各种移动终端、物联网、健康医疗、智能家居等超多个领域 “大显身手” 啦。BLE 所在的单模蓝牙也就是低功耗蓝牙模式拥有低功耗、快连接、长距离这三大 “神奇技能”厉害得不行像 EC200U、EC600U、EG915U、EG912U 这些型号都支持 BLE 功能是不是超给力低功耗方面它就像一个超级节能小卫士。很多物联网设备用的是小小的纽扣电池要是普通bt技术可能没多久就没电 “罢工” 了可 BLE 一来设备靠着纽扣电池能欢欢喜喜地持续工作数月甚至数年呢这对那些不方便频繁换电池的设备来说简直就是救星呀像智能门锁天天坚守岗位有了 BLE完全不用担心它突然没电打不开门啦。蓝牙联盟还给低功耗蓝牙制定了一些超有用的标准 Profile这 Profile 就像是数据规范只要设备都遵守这个规范不管是哪个厂家生产的蓝牙设备都能开开心心地相互连接、愉快通信。就像无线蓝牙键盘鼠标不管你用的是安卓、iOS 还是 Windows 系统都能即插即用这就是 “标准” 的强大力量。低功耗蓝牙还能自定义 Profile这可太好玩了随着智能手机越来越普及这个特性被发挥得淋漓尽致也让低功耗蓝牙的应用领域变得更广阔啦。比如说我们可以自定义一个开关量的 Profile规定数据 01 表示开灯数据 00 表示关灯这样手机发送 01 或者 00就能轻松控制灯的亮灭类似这样有趣又实用的应用可多着呢。代码示例大放送话不多说直接上硬菜 —— 代码示例来啦这份代码可是实现 BLE 服务器端功能的关键让你的模组能愉快接收手机发送的数据哦# -*- coding: UTF-8 -*- import ble import utime BLE_GATT_SYS_SERVICE 0 # 0-删除系统默认的GAP和GATT服务 1-保留系统默认的GAP和GATT服务 BLE_SERVER_HANDLE 0 _BLE_NAME Quec_BLE_UART_Chic event_dict { BLE_START_STATUS_IND: 0, # ble start BLE_STOP_STATUS_IND: 1, # ble stop BLE_CONNECT_IND: 16, # ble connect BLE_DISCONNECT_IND: 17, # ble disconnect BLE_UPDATE_CONN_PARAM_IND: 18, # ble update connection parameter BLE_SCAN_REPORT_IND: 19, # ble gatt client scan and report other devices BLE_GATT_MTU: 20, # ble connection mtu BLE_GATT_RECV_WRITE_IND: 21, # 当ble客户端写入特征值或描述符时服务器收到通知 BLE_GATT_RECV_READ_IND: 22, # 当ble客户端读取特征值或描述符时服务器收到通知 BLE_GATT_RECV_NOTIFICATION_IND: 23, # 客户端接收通知 BLE_GATT_RECV_INDICATION_IND: 24, # 客户端接收指示 BLE_GATT_SEND_END: 25, # 服务器发送通知并收到发送结束通知 } class EVENT(dict): def __getattr__(self, item): return self[item] def __setattr__(self, key, value): raise ValueError({} is read-only..format(key)) event EVENT(event_dict) def ble_callback(args): global BLE_GATT_SYS_SERVICE global BLE_SERVER_HANDLE event_id args[0] status args[1] print([ble_callback]: event_id{}, status{}.format(event_id, status)) if event_id event.BLE_START_STATUS_IND: # ble启动 if status 0: print([callback] BLE启动成功) mac ble.getPublicAddr() if mac ! -1 and len(mac) 6: addr {:02x}:{:02x}:{:02x}:{:02x}:{:02x}:{:02x}.format(mac[5], mac[4], mac[3], mac[2], mac[1], mac[0]) print(BLE公网地址 : {}.format(addr)) # 一系列初始化操作... # 此处省略部分代码完整代码见git官网哦 ret ble_adv_start() if ret ! 0: ble_gatt_close() return else: print([callback] BLE启动失败啦) # 其他事件处理... # 更多代码等你探索哟 # 还有超多实用函数哦 def ble_gatt_server_init(cb): # 服务器初始化函数 pass def ble_gatt_open(): # 开启GATT功能 pass # ...更多函数等你来解锁详细代码示例在https://github.com/QuecPython/example_BLE功能实现超给力这份代码的本事可大着呢执行之后模组就能化身为 BLE 服务器端乖乖接收手机的连接请求。不管是手机发送的普通数据还是文件模组都能稳稳接收并打印出来是不是超厉害就像给你的设备装上了 “顺风耳”轻松听懂手机的 “指令”调试小技巧在调试过程中要是遇到问题别着急。代码里有超多打印信息能帮你轻松找到问题所在。有了它调试 BLE 设备再也不是难题啦 赶紧用起来让你的智能设备畅所欲言吧
