License

Hi, I see you're not maintaining this package anymore. Can you add a license and maybe transfer ownership?

Add incomming call event

Hi,
can this lib be extended to read incoming callerid information for voice supporting modems?

thanks in advance

Too much bugs...

modem.parseResponse = function(response) {
    var plain = response.slice(response.indexOf(':')+1).trim();
    var parts = plain.split(/,(?=(?:[^"]|"[^"]*")*$)/);
    for(i in parts)
        parts[i] = parts[i].replace(/\"/g, '');

    return parts;
}

if(this.queue[0] && this.queue[0]['command'].trim().slice(0, data.length) === data) {
        this.queue[0]['command'] = this.queue[0]['command'].slice(data.length); <= Why you do that ?
        return ;
  }

Please.. any update ?

Does not work with multiple port gsm gateway

I can identify, send and read sms with gammu.

Hey,
The delivery event works well but I would appreciate to have the index of the corresponding SMS so that I can remove it from my Inbox

Text Disappears from end the text message

Hello @emilsedgh first of all nice work.

I have been testing this package and I have found one problem.
Text is disappearing from the end of the message.

In my tests I have detected that 6 characters disappear. Can You Please check this?

TypeError: Cannot set property 'end_time' of undefined

I'm trying to run the following code on Windows 7:

/* Usage: node send_sms.js /path/to/device xxxxyyzz "Foo Bar" */

function err(message) {
  console.log('Usage: node send_sms.js /path/to/device xxxxyyzz "Foo Bar"');
  process.exit();
}

var device   = 'COM11';
var receiver = '5562XX1685XX';
var text     = 'ola mundo';

console.log('iniciando');

var modem = require('modem').Modem();
modem.open(device, function() {
  modem.sms({
    receiver:receiver,
    text:text,
    encoding:'7bit'
  }, function(err, sent_ids) {
    console.log('>>', arguments);
    if(err)
      console.log('Error sending sms:', err);
    else
      console.log('Message sent successfully, here are reference ids:', sent_ids.join(','));
  });
});

But I'm getting the error:

+CME ERROR: operation not allowed

Hi everyone, excuse my English, I'm french,
So I do use this library to send USSD from up to three different sim cards.
So I have three gsm modems connected to my computer and
I'm also able to send USSD over one of them (using Huawei E3131) but the others modems (Alcatel X602D and ) give me this error :
+CME ERROR: operation not allowed.
What should I do? Is there any kind of authorization I should give to my app?

+CMS ERROR: 304

on: modem.sms()
give error : +CMS ERROR: 304

why???

The on ring event doesn't work.

I have connected a FAX modem and connected the land line phone.
The connect function works fine for the modem.
But the on ring event is not triggered when I call the land line phone.
But I can see from the debug feature that the caller id is working fine on my modem.

This is what I get on the console.log when I call at the line line which is connected in my modem:
DEBUG modem: COM19 <----
RING

DEBUG modem: Unhandled command:
NMRB = 6945076867
DATE = 0218
TIME = 2042
MESG = 0000

etc

And below you can see my code.
function onRing(number) {
console.log('onring'+number);
}
var modem1 = new Modem({
ports : ['COM19'],
debug : true
});
modem1.on('ring', onRing);

modem1.connect(function (err) {
if (err) {
console.error('Error connecting modem: ', err);
return;
}

});

GSM module is not working

var device = '/dev/ttyUSB0';
var message = {
text : 'Hello',
receiver: '+91xxxx',
encoding: '7bit'
};

modem.open(device, function(){
console.log('OPEN!!');
});

/*

• Send SMS
  */
  modem.sms(message, function(err, res){
  console.log('SMS', err, res);
  });

OUTPUT:

node gsm_modem.js
OPEN!!

It can't send sms. 'delivery' method is also not working.

How use phones like +7912xxxxxxx?

How use phones like +7912xxxxxxx. Russian style.
But 8912xxxxxxx is ok.

Random behaviour fr receiving messages

Hey,
First thanks for your cool package. I use it to send and receive SMS but sometimes, the app stop receiving SMS (no event is emited when a new sms arrives). I have to stop and restart the app in order to receive them?
Have you ever experiences this behaviour ?

Best SMS Modem MultiSIM

Hi Emil,
Please, what multi sim modem (minimum 3) advise you for your system? or one you advice?
Thank you in advance for your answer.

AT+CNMI accept only first SIM (in dual sim case)?

app.set('port', process.env.PORT || 3000);

var server = app.listen(app.get('port'), function() {

}

app.js is where l try to initialize the modem

Cutting off last characters sending SMS

When using the modem.sms function I am experiencing that the last few characters are cut of when viewing the sms message on the receiving phone.

function sendSMS() {
console.log('Attempting to send SMS');
modem.sms({
receiver: '0761234567',
text: 'Test text from app.js on Mac.',
encoding: '7bit'
}, function (err, sent_ids) {
console.log('>>', arguments);
if (err)
console.log('Error sending sms:', err);
else
console.log('Message sent successfully, here are reference ids:', sent_ids.join(','));
});
}

For instance: Test text from app.js on Mac. gets cut off toTest text from app.js on M

Have you experienced this?

Thanks
Leon

Can't send SMS: this.queue is empty

I'm executing following program:

var modem = require('modem').Modem();
modem.open('COM4', function() {
    modem.execute('AT+CMGS="03028461532"\rHello World\r'+String.fromCharCode(26)+'\r',
    function(err, result){
        if(err) console.log(err);
        console.log('Result: ' + result);
    });
});

this.queue is empty. Witch raises an error.

send several messages to same recipient with short delay between each message

Hey, sorry me again...
When I send 2 long SMS (ie 3 messages concatenated in one) to same recipient almost simultaneously, my messages are received upside down, ie the beggining of the 1st message is concatenated with the end of the second and so on...
I don't know if this is due to the sender SIM card, the receiver SIM card, the modem.js programm, the phone itself
Any idea of how to avoid that?
thanks

modem no longer responds

Hello Emil,

I found that after a certain execution time, the modem no longer responds? Is it a full buffer problem? or other?
I have to restart regularly features to the catcher sms works.
Have you already seen this problem? Did you reference a modem that everything is working properly?

Happy holidays to you, Hervé

on sms received doesn't work...

Huawei E3131.

var modem = require('modem').Modem();

modem.open('/dev/ttyUSB0', function(){
console.log('open');
modem.on('sms received', function(){
console.log('rcvd');
});
});

When sending sms to the modem number, nothing happens. Modem is opened successfully, as I can send sms. Any idea why and how to debug that?

huwaie e303 modem. Able to send sms; Not able to receive.

Hello Emil,
Thanks for the excellent work.
I am trying simple code to send and receive sms on raspberry pi using e303 modem.
I am able to send the message. But read message returns no messages. Also receive message does not receive any.
If I check the messages with gammu -getallsms, I see all of them on SIM inbox folder.
