ESP32 Flashing upload starts and fails with timeout
问题 I have an ESP32-WROOM, as seen here. In the Arduino IDE, I compile and verify my sketch, and then attempt an upload. I get the following error: esptool.py v2.1 Connecting........___ Chip is ESP32D0WDQ6 (revision (unknown 0xa)) Uploading stub... Running stub... Stub running... Changing baud rate to 921600 Changed. Configuring flash size... Warning: Could not auto-detect Flash size (FlashID=0xffffff, SizeID=0xff), defaulting to 4MB Compressed 8192 bytes to 47... A fatal error occurred: Timed

Google iot MQTT - ESP32 Connects the first time and only reconnects after 30m
问题 I'm working with google Iot cloud with ESP32, I am sending fake values just to make a test with the MQTT data PUB/SUB, Apparently I'm succeeding in publishing the values, sometimes, I can't reconnect to google iot. I don't know why it keeps checking wifi...publising and doest check for the JWT key. I have noticed that if I connect once to the google iot and then I unplug the esp32 from my pc (disconnect no power), and plug it back again and try to connect, I will enter in this "checking wifi"
Stream esp-32 camera to RTMP server like YouTube
问题 I am doing research for a project in which I need to play with camera streams. After multiple hit and trails and googling I am not getting even close to the solution for streaming ESP-32 Camera stream to my own RMTP server directly. Already tried solutions: 1) I have tried re-streaming of ESP-32-cam with Raspberry pi, that works well but not something I am looking for {discarded because do not want to use Raspberrypi for restreaming purposes} 2) ESP-32-cam: Record and FTP transfer with time

手机、ESP32单片机、MQTT服务器连接实验
实验目的：通过自己制作的手机APP，连接MQTT服务器，获取ESP32单片机的温湿度信息，控制ESP32单片机上的LED开关。 实验准备： 1、硬件：ESP32开发板（型号不限，esp01s也可以）、LED灯、DH11温湿度传感器、面包板等 2、软件： （1）arduino软件，可以到官网 https://www.arduino.cc/en/Main/Software 下载。 （2）App Inventor 2 集成版，可以到官网 https://www.wxbit.com/ 下载。（解释一下：这个软件是适用于初学者的手机APP制作软件，界面设计所见即所得，程序设计通过拖拽积木块来实现。） （3）需要一台服务器。（可以是自己的电脑，也可以到网上买云服务器，笔者是购买的腾讯云服务器（每年79元），除了运行网站外，再捎带着提供MQTT服务。） 实验步骤： 一、总体设想 1、建一个MQTT服务器，提供订阅/发布 消息的功能。 2、用App Inventor 2 制作一个APP，功能是连接MQTT服务器，订阅ESP32单片机的温湿度信息，控制ESP32单片机上的LED开关。 3、为ESP32编写程序并烧录，完成连接MQTT服务器，发布温湿度信息，订阅LED控制主题，根据消息来开、关LED灯。 二、MQTT服务器的建立 MQTT是IBM开发的一个即时通讯协议
两板之间的ESP32客户端-服务器Wi-Fi通信（兼容ESP8266）
本指南展示了如何在两个ESP32板之间设置HTTP通信，以通过Wi-Fi在不连接互联网（路由器）的情况下交换数据。 简而言之，您将学习如何使用HTTP请求将数据从一个板发送到另一个板。 ESP32开发板将使用Arduino IDE进行编程。 为了演示的目的，我们将BME280传感器的读数从一块板发送到另一块板。接收器将在OLED显示屏上显示读数。 ESP32，更多了解 观看视频演示 视频截图 项目概述 所需零件 安装库 异步Web服务器库 BME280库 I2C SSD1306 OLED库 ESP32服务器（接入点） 原理图 ＃1 ESP32服务器的Arduino Sketch 代码如何工作 测试ESP32服务器 ESP32客户端（站） 详情参阅http://viadean.com 来源： CSDN 作者： 国外课栈 链接： https://blog.csdn.net/jiyotin/article/details/104638968
