PULSE is a layered protocol stack. The link layer provides integrity-assured delivery of packet data. On top of the link layer is a suite of transport protocols which provide multiprotocol delivery of application datagrams with or without guaranteed reliable in-order delivery. Application protocols use one or more of the available transports to exchange datagrams between the firmware running on a board and a host workstation.
This repo provides a TypeScript implementation of the protocol stack with minimal dependencies.
import SerialPort from 'serialport';
const port = new SerialPort('/dev/cu.usbmodem01013');
const intf = Interface.create(port); // Port can be any duplex stream
intf.getLink(async link => {
const transportType = 'reliable'; // reliable or bestEffort
const port = 0x3e20; // Port number specific to your usage, must be <= 65535
const socket = await link.openSocket(transportType, port);
socket.on('data', msg => console.log(`RX data: ${msg}`));
socket.send(Buffer.from('Hello world!'));
});
