node-ptpv2

node-ptpv2

IEEE 1588-2008 PTPv2 Client for NodeJS. Tested with ptp4l and in an AES67 Network. Needs to be executed with priviliges, because the PTP client has to bind to ports below 1024. Implements Delay_req and Delay_resp syncing only.

Install

npm install ptpv2

Usage

Example usage:

var ptpv2 = require('ptpv2');

ptpv2.init('192.168.1.100', 0, function(){
	var synced = ptpv2.is_synced();
	var ptpMaster = ptpv2.ptp_master();
	var time = ptpv2.ptp_time();

	console.log(synced, ptpMaster, time);
});

This should output true '08-00-27-ff-fe-26-55-1f:0' [ 1591294070, 112285378 ] when synced to a master.

ptpv2.init(address, domain, callback)

Initialize the PTP system. Needs the address of the interface on which the multicast group binds to. Also takes the PTP domain number (0 - 3) and a callback that is executed, when the client synced to the master.

ptpv2.is_synced()

Returns false when not synced to a PTP Master and true when it is synced.

ptpv2.ptp_master()

Returns the current PTP Master

ptpv2.ptp_time()

Returns the current synced up time in an array format as follows: [seconds, nanoseconds].
