Ever need a serial port far away from your Raspberry Pi? Wish you could use WiFi to talk to a serial device without having to run a wire? This project is for you.
sudo npm i -g remote-serial-pico
remote-serial-pico i
Now a server is running on the Pi. If you plug in a Pico to the USB it will install the client code on the pico within 6 sec and make it a remote serial port.
/dev/pts/pty1
It's that easy to setup a remote serial port. Each time you plug in a pico, it will be the next ptyN
on the list.
If you haven't already installed npm:
sudo apt update
sudo apt install nodejs npm
Designed to facilitate communication between a remote device (such as a Raspberry Pi) and a device connected via serial to the Pico. It leverages TCP/IP networking to bridge data exchange between the Pico's serial interface and a networked environment. Extend this project using either the node-red-bridge
or homebridge-tcp-smarthome
.
Curious about PtyServer?
pico_{N}
, and creates a pseudo terminal(pty) for each Pico.tail -f /tmp/smartHome.log
Wondering how plugging Pico into the Pi installs client code in Pico?
And what exactly does PicoScriptDeployer do?
wifi-ssid, password, IP, Pico-Serial-ID
and updates the corresponding credentials on config.json. You can also manually update it.main.py
and config.json
to the most recently connected pico.tail -f /tmp/deployer.log
Now, what's the role of the main code in Pico?
