My first attempt: to start socket.io listening ONLY after retrieving the
initial values from DB (I presume your led data can be retrieved via
ledxx.get(),
If this code works, then you could refactor a bit, to a clear
initialization, now all the code is inside a "big" callback. But, baby
steps ;-)
Server.js
if(start==0)
{
db.get('4662745328718336f506f9d2d3010c0c', function(err, val) {
console.log('Switches =', val);
led10.set(val.sw1);
led11.set(val.sw2);
led12.set(val.sw3);
// I moved your code here, in the db.get callback
io.sockets.on('connection', function (socket) {
socket.emit('fromserver', {sw1:led10.get(),sw2:led11.get(),swt3:led12.get()
});
socket.on('fromclient', function (data) {
if (data.l10==true)
led10.setHigh();
if (data.l10==false)
led10.setLow();
if (data.l11==true)
led11.setHigh();
if (data.l11==false)
led11.setLow();
if (data.l12==true)
led12.setHigh();
if (data.l12==false)
led12.setLow();
});
});
});
start=1;
}
