Question 1

How to install serialport on Raspberry Pi?

Accepted Answer

Use npm install serialport after setting up Node.js on the Pi, but ensure you have build tools installed for native add-ons, as the library compiles platform-specific binaries. Refer to the guides on serialport.io for detailed steps.

Question 2

Node serialport vs Python pyserial, which is better?

Accepted Answer

Node serialport is ideal for JavaScript/Node.js ecosystems and web-integrated projects, while pyserial suits Python-based applications with simpler syntax and broader hardware library support. Choose based on your stack and performance needs.

Question 3

Why is my serialport connection dropping data?

Accepted Answer

This often stems from buffer overflows or incorrect baud rate settings; ensure you configure flow control and use the stream API properly to handle data asynchronously without blocking.

Question 4

How to list all serial ports with node-serialport?

Accepted Answer

Use the SerialPort.list() method, which returns a promise with port details like path and manufacturer. Example code is in the API docs on serialport.io.

Question 5

Can I use serialport with Electron for desktop apps?

Accepted Answer

Yes, it's compatible with Electron, but you may need to rebuild native modules for the target platform using electron-rebuild. Check the guides for cross-platform desktop integration.

Question 6

Serialport error: permission denied on Linux, how to fix?

Accepted Answer

Add your user to the dialout group with sudo usermod -a -G dialout $USER, or run the app with sudo, though the latter is less secure. This is common for raw hardware access.
