SeedlinkConnection

src/seedlink4.ts

A seedlink websocket connection to the given url. The connection is not made until the connect() method is called. Note this cannot connect directly to a native TCP socket, instead it sends the seedlink protocol over a websocket. Currently only the IRIS ringserver, https://github.com/iris-edu/ringserver, supports websockets, but it may be possible to use thrid party tools to proxy the websocket to a TCP seedlink socket.

new SeedlinkConnection(url: string, requestConfig: Array<string>, receivePacketFn: function (packet: SEPacket): void, errorHandler: function (error: Error): void)

Parameters

url (string) websocket URL to connect to

requestConfig (Array<string>) an array of seedlink commands like: [ 'STATION JSC CO', 'SELECT 00BHZ.D' ]

receivePacketFn (function (packet: SEPacket): void) the callback function that will be invoked for each seedlink packet received.
