Ardunio ESP32 BLE Client Notify数据长度 概述 CAN(Controller Area Network)总线协议是由 BOSCH 发明的一种基于消息广播模式的串行通信总线,它起初用于实现汽车内ECU之间可靠的通信,后因其简单实用可靠等特点,而广泛应用于工业自动化、船舶、医疗等其它领域。相比于其它网络类型,如局域网(LAN, Local Area Network)、...
We are testing the BLE_notify example. We tested with two means of connection, from a ESP32 running BLE_client without turning on/off notification, and it will stuck. We also tested connection from "nRF connect" from an iphone, it also stuck. Any hint? I was thinking if BLE_notify...
The sketch provided is a modified version of the BLE Notify example. This bug appears to be the same as the one found by@mirozmrzliinthis discussion Edit: The problem found by@mirozmrzlimay be unrelated, as he was using idf toolchain v4.4 and latest arduino lib ...

ESP32,IDF版本5.1.2。连接某一ble设备,版本据说是5.0,没法验证,通过手机BLE调试APP操作反应正常,其通知和写特征值是分开的,注册NOTIFY服务后,写入成功后,设备会自动应答,但NOTIFY动作无反应。 Code:Select all I (7578) GATTC_DEMO: ESP_GATTC_CONNECT_EVT conn_id 0, if 3 I (7578) GATTC_DEMO: REMOTE...

BLE蓝牙通讯的传输的数据量较小,以二进制方式通讯,效率较高。Protocol Buffer为Google推出的二进制传输模式,速度快,开发方便,非常适合做蓝牙的应用层通讯协议。 使用Protocol Buffer, 需要编写接口文件,扩展名一般为.proto 如example.proto: syntax = "proto3"; message device_info { string id=1; string type=2...
