  I'em frontend developer, and I know JS pretty well.

  everything works, the sensors are detected. The problem is that in one example ASSERT is an error, in the second one runs out of memory.
  you don't even need to look at my code, the same problem will be copying the example from the espuino website

  ASSERT(jsvGetLocks(var) < 15) FAILED AT src/jsvar.c:721
  

  this error also occurs if you call the ws.send("....") 15 times (by https://www.espruino.com/ws#websocket-se­rver)

  ....
  var server = require('ws').createServer(onPageRequest­);
  var clients = [];
  server.listen(8000);
  server.on("websocket", function(ws) {
      clients.push(ws);
      ws.on('message',function(msg) { print("[WS] "+JSON.stringify(msg)); });
      ws.send("Hello from Espruino!");
  });
  
  
    setInterval(function(){
      clients.forEach(ws => ws.send('....'));
  //after 14 events ERROR ASSERT(jsvGetLocks(var) < 15) FAILED AT src/jsvar.c:721 
    },5000);
  
  .....
  

  This dirty example helps, but not nice

    setInterval(function(){
        var cc = clients.map(ws => {
          ws.send('....');
          return ws.clone();
        } );
        clients =cc;
      
    },5000);

  How many sensors are attempted to be traversed using the forEach?

  About 8 sensors.

  I do not know enithing , i only use code from example

  does anyone have any ideas how to fix this?

  Any implementation works poorly, each approach has different problems
  this example by https://www.espruino.com/DS18B20

  owMultiSensors = new OneWire(D4);
  DSlib = require("DS18B20") ; 
  var sensors = owMultiSensors.search().map(function (device) {
      return DSlib.connect(owMultiSensors, device);
    });
   
    setInterval(function() {
      sensors.forEach(function (sensor, index) {
      sensor.getTemp(function (temp) {
        console.log(index + ": " + temp + "°C");
      });
    });
  
  }, 1000);
  
  

  After several seconds the error:

  ASSERT(jsvGetLocks(var) < 15) FAILED AT src/jsvar.c:721
    #1[r3,l2] Object {
      #2[r1,l2] ASSERT(jsvGetLocks(var) < 15) FAILED AT src/jsvar.c:701
  HALTING.
  

  If sensors search put to set Interval this problem disappears , but other appears

  owMultiSensors = new OneWire(D4);
  DSlib = require("DS18B20") ; 
  setInterval(function() {
    var sensors = owMultiSensors.search().map(function (device) {
      return DSlib.connect(owMultiSensors, device);
    });
      sensors.forEach(function (sensor, index) {
      sensor.getTemp(function (temp) {
        console.log(index + ": " + temp + "°C");
      });
    });
  }, 1000);
  

  This code fills all RAM in time and device stops working
  Interval time increase does not have any influence, it only delays the time of crash

• Guru Meditation Error with pin setWatch

  in ESP32 • 3 years, 2 months

  

  I have error after press the button

   pinMode(D35, 'input_pulldown');
    setWatch(function(e) {
      console.log('bttn pressed');
    }, D35, { repeat: true, edge: 'rising' });
    
  

  with D34 also this same error, D15 work

  This work fine, but I don want to use setInterval

  setInterval(function() {
    console.log( digitalRead(D34));
  }, 100);
