This let you know connection state to your obniz Board as string value.
var obniz = new Obniz('1234-5678');
console.log(obniz.connectionState) // => === "connecting"
obniz.onconnect = async function() {
console.log(obniz.connectionState) // => === "connected"
}This lets obniz.js to show logs like communicated jsons and connection logs in console.log.
var obniz = new Obniz('1234-5678');
obniz.onconnect = async function() {
obniz.io0.output(true);
}This variable indicate installed firmware version of target device
var obniz = new Obniz('1234-5678');
obniz.onconnect = async function() {
console.log(obniz.firmware_ver) // ex. "2.0.0"
}This variable indicate connected hardware identifier of target device
var obniz = new Obniz('1234-5678');
obniz.onconnect = async function() {
console.log(obniz.hw) // ex. "obnizb1"
}obniz id
Is node.js environment or not.
Device metadata set on obniz cloud.
var obniz = new Obniz('1234-5678');
obniz.onconnect = async function() {
console.log(obniz.metadata.description) // value for "description"
}onclose will be called when disconnected.
var obniz = new Obniz('1234-5678');
obniz.onconnect = async function() {
}
obniz.onclose = async function() {
}Once connection is established, onconnect function will be called.
var obniz = new Obniz('1234-5678');
obniz.onconnect = async function() {
}Operations like turning on/off an io becomes possible only after connection is established, so any operations you want obniz Board to undertake must be written in onconnect
var obniz = new Obniz('1234-5678');
obniz.onconnect = async function() {
obniz.io0.output(true);
}If an error occurs, the onerror function is called.
var obniz = new Obniz('1234-5678');
obniz.onconnect = async function() {
}
obniz.onerror = async function(ob, error) {
console.error(error);
}Called continuously while obniz device is online. Put your main code inside of onloop and put your setup code inside of onconnect.
onloop will be called after onconnect called. If your funciton set to onconnect return promise, onloop wait until done promise. Even onconnect throws an error onloop will start.
onloop call pingWait() every time to keep connection data buffer between device to your software clean.
var obniz = new Obniz('1234-5678');
obniz.onconnect = async function() {
}
obniz.onloop = async function() {

This closes the current connection. You need to set auto_connect to false. Otherwise the connection will be recovered.
var obniz = new Obniz('1234-5678', {
auto_connect: false,
reset_obniz_on_ws_disconnection: false
});
obniz.connect();
obniz.onconnect = async function() {
obniz.io0.output(true);
obniz.close();
}This closes the current connection. You need to set auto_connect to false. Otherwise the connection will be recovered.
var obniz = new Obniz('1234-5678', {
auto_connect: false,
reset_obniz_on_ws_disconnection: false
});
obniz.connect();
obniz.onconnect = async function() {
obniz.io0.output(true);
await obniz.closeWait();
}You can connect to obniz Board manually by calling connect() when auto_connect is set to be false.
var obniz = new Obniz('1234-5678', { auto_connect: false });
obniz.connect();
obniz.onconnect = async function() {
obniz.io0.output(true);
}With this you wait until the connection to obniz Board succeeds.
var obniz = new Obniz('1234-5678');
await obniz.connectWait();
obniz.io0.output(true);
await obniz.closeWait();
var obniz = new Obniz('1234-5678');
await obniz.connectWait({timeout:10}); //timeout 10sec
if(connected){
obniz.io0.output(true);
await obniz.closeWait();
}If the param auto_connect is set as false, it will try to connect only once and, if unsuccessful, return false.
var obniz = new Obniz('1234-5678',{auto_connect: false});
var connected = await obniz.connectWait(); //try once
if(connected){
obniz.io0.output(true);
await obniz.closeWait();
}False will be returned when connection is not established within a set timeout.
