Developing ESP32 with VS Code on Linux

By -

The following procedure shows how to build ESP32 microcontroller projects with the Visual Studio Code Integrated Development Environment on Debian-based Linux distributions.

==========

1. INSTALLATION

1.1. Install Espressif's IoT Development Framework for ESP32 with the RTOS SDK.

1.2. Download and install the Visual Studio Code IDE.

2. PREPARATION

2.1. On the VS Code menu, go to [ File -> Open Folder... ] and open the target ESP32 project folder.

Example: ~/esp/esp-idf/examples/get-started/hello_world

2.2. On its bottom panel, click on the Terminal tab. This will automatically change to the location of the opened folder.

2.3. Temporarily add the ESP-IDF toolchain to the shell path.

user@host: $ . ~/esp/esp-idf/export.sh
or
user@host: $ source ~/esp/esp-idf/export.sh

2.4. Verify if the toolchain has been added to the shell path.

user@host: $ echo $PATH

3. UTILIZATION

3.1. Maximize the bottom panel size and configure the IDF settings for the project.

user@host: $ idf.py menuconfig

3.1.1. Use the arrow keys to highlight menu items.
3.1.2. Press "s" to [ Save ] the current settings.
3.1.3. Press "q" to [ Quit ] the menu.

3.2. Restore the bottom panel size and remove old build files, if any.

user@host: $ idf.py clean

3.3. Build the ESP32 project binaries.

user@host: $ idf.py build

3.4. Flash the binaries to the ESP32 microcontroller.

user@host: $ idf.py flash

Enabling HTTPS in Home Assistant

By -
Image
The following procedure activates HTTPS for the Home Assistant server. The secure protocol uses TLS/SSL certificates to encrypt the data transferred between user and server. Although it is possible to make this home automation system, whether in  Linux or  FreeBSD , accessible over the Internet, Home Assistant is usually operated within private networks, either physical or virtual. In this case, self-signed certificates may be acceptable to use and quicker to deploy. ========== 1. Log in as the system account. 1.1. Linux, with $HOME "bin" included in $PATH (-i) of system account (-u). user@host: $ sudo -i -u homeassistant 1.2. FreeBSD, coming from "root" superuser. root@host: # su - homeassistant 2. Go to the Home Assistant configuration directory. user@host: $ cd ~/.homeassistant 3. Make a directory for SSL certificates. user@host: $ mkdir ssl 4. Ensure that only the system account and members of its group can access the directory. user@host: $ chmod 7

Configuring the FreeBSD Firewall with IPFW

By -
Image
IPFW is one of several firewalls included in FreeBSD by default. It has a command-line tool to handle the policies for incoming and outgoing connections. In the configurations discussed here, network connections "from any to any" are deliberately avoided to prevent potential bounce attacks from happening, if the server is not intended to act as a router. Instead, a request/respond or incoming/outgoing rule pair is adopted to direct the flow of network traffic. The main objective is to set up IPFW to block unauthorized remote access to unsecured ports on the server. But if attackers manage to break in through a vulnerability on some programs running on authorized incoming ports, the outgoing restrictions will prevent massive data exfiltration, stopping intruders dead in their tracks. A similar approach can be done on Debian-based Linux distributions using UFW . ========== 1. STRICT CONFIGURATION 1.1. Create a custom shell script for IPFW commands. root@host: #  ee /etc/myip

Running Home Assistant on FreeBSD Servers

By -
Image
Home Assistant is an open-source home automation system powered by Python, primarily intended to run on single-board computers like the Raspberry Pi, with Linux as the host operating system. The following procedure shows how to run Home Assistant Core on FreeBSD servers, on either physical or virtual machines. ========== 1. PREPARING THE SERVER 1.1. Update the package list and upgrade the existing packages. root@host: # pkg update && pkg upgrade -y 1.2. Install Python and other required packages. root@host: # pkg install python38 py38-sqlite3 openssl autoconf libffi rust 1.3. Create a system account with disabled login (-w no), a dedicated home directory (-m), and some informational text (-c comment). root@host: #  pw useradd homeassistant -w no -m -c "Home Assistant" 1.3.1. If groups for hardware input/output are present, append the system account. Else, skip this step for now. root@host: #  pw groupmod gpio -m homeassistant root@host: #  pw groupmod i2c -m homeassis
