Hello again,

I still have the problem that 12 bytes are missing at the end of my file, when I use the pipe function like I wrote in my last post. Any ideas what I could do to get it working? I use the code above with a chunkSize of 512.

Best,

Hello,

I have firmware 0.924 as recommended in the documentation and I have a similar problem. The callback function of the connect function of the driver is never getting called. I checked the response of the ESP8266 by using Serial4.on('data', ...) and I got the AT+CWJAP error as well.

AT+CWJAP="",""

ERROR

I am using Espruino 1.75.

For me it is very important as well

Great, thank you Gordon!

Hello,

when I execute the following code in the browser or in Node.js, I see the console log with the value 4. In Espruino nothing happens. Do you have an idea why?

var x = new Function([ 'a' ], 'console.log(a);');
x.apply({}, [ 4 ]);

A workaround could be:

var date = new Date();
var future = new Date(date.getFullYear(), date.getMonth(), date.getDate(), 12, 0, 0);
console.log(future.toString());

Hello again,

I experienced that the Date class has no setters like:

Date.setHours(Number);
Date.setMinutes(Number);
Date.setSeconds(Number);
...

How can I create a new Date() object for example for today, but time of day 12:00 for example?

In regular JavaScript I write something like this:

var d = new Date();
d.setHours(12);
d.setMinutes(0);
d.setSeconds(0);

In Espruino this doesn't work :(

You mean to calculate the milliseconds to be in sleep mode until the next alarm comes up? Could be an idea.

Hello everyone,

I plan to let my Espruino wake up on a specific alarm time. In the meantime the board should be ideally in deep sleep mode.

Is there a better way to realize that instead of waking the board by an interval to check the time frequently?

Maybe there could be a feature "setWatchTime" in the future.

It seems to be a timing problem of the asynchronous calls. I experienced situations where it worked with the same function and the same data without any changes being made. But for now it is not working for me.

Both workarounds don't work for me. The response is closed too fast, so the on-handlers for "close" and "data" are not getting called, because it is too late.

Thank you!

Hi Gordon,

with a bigger file the close handler is getting called and it works as expected.

Dear community,

sorry for writing again about problems I experienced with Espruino. I used the latest build of 1.75.

I experienced that the "close" event of the http response is not raised for the same get request. No matter how often I try. On the other side I am using the Express JS framework. With other HTTP clients it works well.

    var request = function() {
        var body = "";
        var options = {
            method: 'GET',
            host: '192.168.0.11',
            port: 3000,
            path: "http://localhost:3000/api/Entities/54fa­be55ef581d7d5f8bcac1/tasks?filter[where]­[active]=true&filter[fields][id]=true&ac­cess_token=I9sbI5cy6m1gHONeNmCHULGX4CwSG­BzC0RDdnPDCfMW4or2UmDyxWg0ZbnQAT1yN",
            headers: {
                "Content-Type": "application/json",
                "Content-Length": body.length
            }
        };
        var contents = "";
        var req = require('http').request(options, function(res) {
            console.log(res);
            res.on('data', function(data) {
                contents += data;
            });
            res.on('close', function() {
                console.log('CLOSE');
                if(res.statusCode === "200" || res.statusCode === "204") {
                    console.log('OK');
                } else {
                    console.log('FAIL');
                }
                contents = "";
            });

        });
        req.on('error', function(e) {
            console.log('Error');
        });
        req.write(body);
        req.end();
    };

The response looks ok:

{
  "headers": {
    "X-Powered-By": "Express",
    "Vary": "Origin, Accept-Encoding",
    "Access-Control-Allow-Credentials": "true",
    "Content-Type": "application/json; charset=utf-8",
    "Content-Length": "2",
    "ETag": "W/\"2-d4cbb29\"",
    "Date": "Wed, 11 Mar 2015 13:30:53 GMT",
    "Connection": "close"
   },
  "httpVersion": "1.1",
  "statusCode": "200",
  "statusMessage": "OK",
  "#ondata": function (b) {l+=b}
 }

How can I handle such problems with the http class of Espruino? What is the problem, that the "close"-event handler is not getting called?

Best,

Tobias

I tested again with your recent build from GitHub and it looks much better, but there are 12 bytes missing at the end of the file. It looks like it is getting closed too early.

Perfect, thank you!

One additional question while we are speaking about http:

Is there a way to get the statusCode of the responses? res.statusCode is set to undefined.

No idea?

Dear community,

I tried to pipe an http response directly to a file to save RAM. I experienced that sometimes the file contains the right content, sometimes it contains strange characters. Furthermore the "complete" function defined in the pipe options is never getting called.

I formatted the SD card before I tested and I typed E.unmountSD() to be sure that it is not a problem with the SD card filesystem.

Could you please help me? Below you find the function.

Best,

Tobias

var downloadFile = function(path, filePath) {
    var file = E.openFile(filePath, 'w');
    var body = "";
    var options = {
        method: 'GET',
        host: '192.168.0.11',
        port: 3000,
        path: path,
        headers: {
            "Content-Type": "application/json",
            "Content-Length": body.length
        }
    };
    var req = require('http').request(options, function(res) {
      res.pipe(file, { chunkSize : 32, end: true, complete: function() { console.log('Complete'); } });
      res.on('close', function() {
        console.log('Closed.');
      });
    });
    req.write(body);
    req.end();
};

Any news about the implementation of GPRS support?

When I plug in getTime is working like a charm. I will test what it shows after one day running.

setInterval() didn't work as well

No problem. Thank you for your support so far. If I find out what's happening I'll inform you again.

I used the offical JST connector and soldered it to a 9V clip. I am using that clip with a battery holder for 8 * 1,2 V accumulators. I'll try to use other batteries.

As well I will do the tests with another Espruino Board again.

I am currently using firmware version 1v73. Did you try to power the board just by a battery and disconnect the USB cable as well? It just happens in this particular setup.

This will be the next thing I will try when setInterval() did not succeed.

The strange thing is, when it stopped working, all the time when I reconnected the device to USB it continued working for some time.
