Sumerizing: The ways and implementations for assigning wifi passcode to ESP32/ESP8266 MCU Assigning WiFi pass code to ESP chip is ubiqutous. To summerize, we can do it with ways listed below: AP mode: A web running on chip, Chip working as Station mode. Bluethooth. (ESP8266 has no bluetooth moduel.) ESP Touch App with ESP smartConfig© solution. (5G Hz is not supported.) others, such as AP-STA link by routers, AP by cellphone, wifi manag-frame broadcasting. Comparations with methods above: Tech Methods UserConfident SuccessRate Popularity softAP Mode middle High High SmartConfig High Low High Bluetooth High High middle (esp8266 has no BLE) Ps: ESP32:Update Wi-Fi Credentials Using Bluetooth Application, link

Let me share some thoughts bout creating academic research paper. How to find the innovative ideas for a new paper A new idea is believed by the newbee PhD student a precious seed for his/her paper. And the papers are believed as their lifesaver for their tough days. Solution: a. adjust the mindset. A book named as ‘phD grind’ written by Philip Guo may helps. b. In your research area, hack up a classical work, a hot research work, a gorgeous work or a work you just want to hack up.

How to use LittleFS on ESP32 with vsCode+platfromIO As a suplement of this tutorial How to use LittleFS on ESP8266 I follows some reference and examples to build this blog. Get to konw some basic introductions about SPIFFS and LittleFS on ESP8266 and ESP32 is necessary for a noob. Note: Most of the functions for SPIFFS operations are compatible for LittleFS. follow the tutorials one by one: - SPIFFS for ESP8266 - SPIFFS for ESP32 - LittleFS for ESP8266 - LittleFS for ESP32 LittleFS is newly introduced into ESP32 SDK (Aug 2021) .

Install Fail2Ban On CentOS 7 Posted on December 13, 2019 by David Singer What Is Fail2Ban? Fail2ban is an open-source software that actively scans the servers log files in real-time for any brute force login attempts, and if found, summarily blocks the attack using the servers firewall software (firewalld or iptables). Fail2Ban runs as a background process and continuously scans the log files for unusual login patterns and security breach attempts. Installation In order to install Fail2Ban on CentOS 7, we first need to enable the EPEL (Extra Packages for Enterprise Linux) repository.

Fixing certbot does not know where nginx is located in your server If your certbot cannot auto configure ssl for your host: The cause of this problem Mine is because the installation path of nginx is not the default one， such as /etc/nginx or /usr/bin/nginx When Certbot is unable to automatically configure your web: Follow the GPT’s answer: ME: Certbot doesn't know how to automatically configure the web server on this system. GPT: If Certbot is unable to automatically configure your web server, it usually means that it couldn't identify the web server software and configuration on your system.

import esp-idf components: import the components is easy: git clone , mkdir <proj_dir>/components, and copy into <proj_dir>/components The git repos and commands that I used for this testing: git clone https://github.com/natanaeljr/esp32-I2Cbus.git I2Cbus git clone https://github.com/natanaeljr/esp32-MPU-driver.git MPUdriver mkdir -p <proj_path>/components mv I2Cbus <proj_path>/components mv MPUdriver <proj_path>/components for more, refer: https://github.com/natanaeljr/esp32-MPU-driver Do sdkconfig for the right chip and protocal for the imported component if the hello_world_main.c is renamed, rename it in <proj_dir>/main/CMakeLists.txt

[ESP32_lvgl] From demo to own UI component with lvgl on ESP32 This is the FIRST blog for denoting my learning process of lvgl on platform of ESP-IDF for chip ESP32. After a lot of experinment, I gues ESP-IDF should be the best sdk that suit for ESP32 lvgl development. Rather than the toy – micropython. 1. Motivation and value of this post After configuring the ESP32 LVGL development environment, developer will try to run demo on the development board. But for beginners, from running demo to developing the specific project, they may meet some little but not-easy-to-solve difficalties.
