B4R vs nRF Connect for VS Code

B4R is a free Windows development tool for creating native programs for Arduino-compatible boards, ESP8266, and ESP32. Its plan costs nothing and permits commercial use. The product page lists a modern IDE, connectivity options, and an Arduino–Android Bluetooth Low Energy example. Integrated flashing is available, but integrated debugging is not. Setup requires Arduino IDE v2, Arduino CLI, and Java; OpenJDK 14 is listed when Java is not already installed. Users configure paths to arduino-cli.exe and javac, then choose a board type and serial port in the Board Selector. C source code and generated compiled objects appear in the Objects folder. B4R libraries are open source under the MIT license. The product page links learning resources, example projects, tutorials, and a forum. Anywhere Software directs technical questions to its forum and says email inquiries receive answers within 24 hours. The maker identifies Erel Uziel as founder and CEO and says it has specialized in mobile development since 2005.

nRF Connect for VS Code is a free extension for developing, building, and debugging applications based on the nRF Connect SDK. It supports nRF91, nRF70, nRF53, and nRF52 Series devices, with interfaces to the compiler and linker and an RTOS-aware debugger. Configuration tools include a DeviceTree Visual Editor and a Create New Board wizard. The environment includes a built-in terminal and both command-line and graphical interfaces, with integrated flashing listed. The product consists of four Nordic extensions: nRF Connect for VS Code, nRF DeviceTree, nRF Kconfig, and nRF Terminal. Nordic says all four must be installed and used together for the product to work correctly with supported SDKs and provide all features. The main extension is available through the Visual Studio Code Marketplace; Nordic documentation also lists the extensions in the Open VSX Registry for VSIX-compatible editors. It runs on Windows, macOS, and Linux. Nordic identifies nRF Connect for Desktop and nRF Command Line Tools as additional desktop tools, and recommends its nRF Connect SDK Fundamentals course for getting started. Nordic Semiconductor is headquartered in Trondheim, Norway, and was established in 1983.
