I miss a property phone_number or number or something like that what will represent number of sim in network. I think it would be usefull.

Lot of modems support command AT+CNUM
if it will return just OK the number is missing in own number phonebook
so we will have to write it to own number phonebook and then AT+CNUM it should work

Or we can read it from the phonebook
Select ON in PB -> AT+CPBS="ON"
Then read the first index -> `AT+CPBR=0``

see

def phone_number(self, default_phone_number= None):
    num = None
    if "AT+CNUM" in supported: # supported check
        resp = self.write('AT+CNUM')
        if resp is not "OK": # if is not only ok and number was returned - TODO
            num = resp
    else:
        actual_phonebook = self.write('AT+CPBS?')
        if actual_phonebook is not "ON": 
            self.write('AT+CPBS="ON"')
        try:
            num = self.write("AT+CPBR=0")
        expect Exception: # TODO Change to specific 
            num = None

        if default_phone_number is not None:
            self.set_phone_number(default_phone_number)
            num = default_phone_number
        else:
            raise Exception('Number not found')

    return num

If you try to send a message under 160 character long, containing some characters which need to be escaped, it is possible that an invalid >160 char single message is generated. It then appears as an empty incoming message on my phone.

12345-010,12345-020,12345-030,12345-040,12345-050,12345-060,12345-070,12345-080,12345-090,12345-100,12345-110,12345-120,12345-130,12345-140,12345-150,[[[[[[[[

This string is 158 char long. It contains 8 brackets which need an escape character, so the real length of the message is 166 septets. It should be split into two SMS, but it isn't.

How to quickly reproduce:

1. open examples/sms_handler_demo.py
2. replace sms.reply.... (line 23) with a static string
   sms.reply('12345-010,12345-020,12345-030,12345-040,12345-050,12345-060,12345-070,12345-080,12345-090,12345-100,12345-110,12345-120,12345-130,12345-140,12345-150,[[[[[[[[')
3. save, start, send sms to modem and wait for the response.
4. my phone receives an empty message
5. copy generated PDU message here: http://rednaxela.net/pdu.php and check the contents by decoding it. It shows something like this:
   123456789,123456789,123456789,123456789,123456789,123456789,123456789,123456789,123456789,12345-100,12345-110,12345-120,12345-130,12345-140,12345-150,€<€<€<€<€<€<€<€< Length:166

This the error am gettings.

As far as I know, there is no way to properly use .format() with Bytes without using .decode().
Maybe it is possible to use Unicode instead of Bytes in modem.py and only use Bytes inside SerialComms.write(), which in my opinion would lead to a much cleaner solution, but it might require more changes.
Also it might be better to carefully use .decode() before .format() only when necessary.
I can keep this changes in my fork until a better solution is found.

May I know what is going wrong?
The SIM card can get a network and send a SMS with a phone.
Ths GSM modem is using SIMCOM SIM800C chip.
Thanks.

Attempting to use gsmmodem with Iridium units (9505(A), 9522, 9555) leaves the connect() method hanging in _unlockPin() and various other places; it looks like the Iridium responses are non-standard enough to cause problems.

Fixing this inline in the existing connect() method looks complicated and might cause problems for existing users, and it seems like it might be better to create an iridiummodem subclass to override connect() and also provide other Iridium-specific functionality; I have a working prototype that could be added into this project if you think it worthwhile?

Obviously I don't mind doing the work and testing the end result with various Iridium handsets and other equipment, but thought it worthwhile asking first :)

Hello All,

Apologies in advance. This is most likely not an issue with this python module, but I am hoping to some help here. Also if such problems are regular with hardware, I wonder if we can somehow make the software more robust.

I am interfacing a SIM800 GSM module with Pi 3 over serial ports (pins 6, 8, 10). While things work OK most of the time, every now and then I get spurious characters in the response. For example, I get:

['+CLCC: 1,0,2,0,0,"+919812x\x9c\xd3\x13\x93\x93\x12)\xa25,""', 'OK']

whereas the expected response is:

['+CLCC: 1,0,2,0,0,"+919812012321,""', 'OK']

As I said, this happens once in a while (may be 1 in 10) and happens with other commands too. Also, this is not the only GSM module or Pi having the problem. So very unlikely hardware issue, unless the GSM module is buggy. The GSM module in question is this http://www.rhydolabz.com/wiki/?p=10450

The baudrate is set to 9600.

What could be going wrong? Could it be bad connections? I usually crimp dupont connectors to the open ends of the cable supplied with the modem. As far as I can tell, the crimps are decently done. How do I fix this?

Thanks,
Pavan

Hi. Is there a plan to add asyncio features to the library ? or is there a way to use pyserial async version for fast asynchronous work

Hi,
do you think that python-gsmmodem work fine on a device with openwrt?
BR

I'm currently testing by sending several texts to the gsm modem (at most 7 at a time), and I think it ruins the threads resulting in TimeoutExceptions. Anyone also experiencing this/tried this?

Sample error:
File "C:\Users\User\Anaconda3\lib\site-packages\gsmmodem\modem.py", line 1354, in _handleSmsReceived
self.smsReceivedCallback(sms)
File "main.py", line 24, in handleSms

File "C:\Users\User\Anaconda3\lib\site-packages\gsmmodem\modem.py", line 66, in reply
...return self._gsmModem.sendSms(self.number, message)
File "C:\Users\User\Anaconda3\lib\site-packages\gsmmodem\modem.py", line 902, in sendSms
...result = lineStartingWith('+CMGS:', self.write(text, timeout=35, writeTerm=CTRLZ))

...responseLines = super(GsmModem, self).write(data + writeTerm, waitForResponse=waitForResponse, timeout=timeout, expectedResponseTermSeq=expectedResponseTermSeq)
File "C:\Users\User\Anaconda3\lib\site-packages\gsmmodem\serial_comms.py", line 144, in write
...raise TimeoutException()

P.S.:
Unless, several text messages at once is too much for a gsm modem to handle?

Greetings.

I would like to know if there is any possible way to get the SMS's index, preferably by using ReceivedSms object. I want to do it mainly for SMS deletion (the idea is that I read an SMS, process it and, afterwards, delete it). Indexes are dynamic and I can't surely predict which index corresponds to which message. If there is another convenient way to delete an SMS by using ReceivedSms object - that would suffice, too.

Thank you!

Hi, nice to see the project live again.

I found that when i send the message to the modem with a long message with different language, English + Non-English,

It seems that nth can be read in the _readLoop and thus the timeout. Any ideas?

Updates:
It works when I set the textmode to True, however, I need to decode the PDU manually.

Would it better to pipe this settings to modem declaration (similar to baudrate and port)? Like so:
modem = GsmModem(PORT, BAUDRATE, dsrdtr=False, rtscts=False, smsReceivedCallbackFunc=handleSms)
My board has wire issue with dsrdtr and rtscts. So dsrdtr=False, rtscts=False help me. But I have to edit serial_comms.py file.

Hey, I've encountered strange bug while decoding some pdu's. I got EncodingError exception on some messages while the others are decoding normally. It seems that a problem is in a function nibble2octet:

def nibble2octet(o):
    if o % 2:
        return o / 2 + 1
    else:
        return o / 2

In Python 3 this function can produce float values. The value is used later in unpackSeptets and comparison with int breaks desired behavior. If it is simple python2->python3 migration issue, it can be fixed simply by return int(o / 2) + 1. Can somebody confirm that fix doesn't break anything else?

Concerning #20.

Previous and current CLIP-RegEx

CLIP_REGEX = re.compile('^\+CLIP:\s*"\+{0,1}(\d+)",(\d+).*$')

does not give a match if unknown number "" or any string (If possible?) is in caller ID. Furthermore, without match, ton cannot be parsed.

     if self._callingLineIdentification and len(lines) > 0:
        clipLine = lines.pop(0)
        clipMatch = self.CLIP_REGEX.match(clipLine)
        if clipMatch:
            callerNumber = '+' + clipMatch.group(1)
            ton = clipMatch.group(2)
            #TODO: re-add support for this
            callerName = None
            #callerName = clipMatch.group(3)
            #if callerName != None and len(callerName) == 0:
            #    callerName = None
        else:
            callerNumber = ton = callerName = None
    else:
            callerNumber = ton = callerName = None

Nevertheless, ton is not empty if the number string is (f.e. if an unknown number is calling). My SIM800 module gives this response

+CLIP: "",128,"",0,"",1

when an unknown number is calling. So at least in this case tonis not at all None, as set currently.

Would it be better to change the RegEx to '^\+CLIP:\s*".*)",(\d+).*$' (Can handle strings as well) so that it always matches, and ton can then be used to distinguish between different types of numbers.

The SIM800 series command manual (v1.01) states:
129 Unknown Type
161 National Number Type
145 International Number Type
177 Network Specific Number

This information might be used for either prepanding the plus sign (for Intl Numbers) or not (Maybe National Number Type does no have the plus sign, unfortunately I can't find any info about this). If the response is 128, 'unknown Number' might be returned instead of the current None

This is not exactly an issue. I would like to know if I can play around the "OADC" or "sender ID" in order to display some name instead of the phone number. Related link.

Is there something already implemented or at least, are there some hints to do it?

In _setSmsMemory (modem.py:715) self.write() with no argument cause TypeError exception:
TypeError: write() missing 1 required positional argument: 'data'

I think it's safe to remove empty self.write(), correct me if I'm wrong.

Hi,do you have a plan to make a simple gsmmodem web server?
I think it's a very good idea .Think about it ,you can send sms from you brower or make phone calls.

As you can see +CSCS is supported

but in array is as bytes
but checking is strig
so return is its not supported

Also with CNUM

so controls should be

if b'+CSCS' in self._commands

if b'+CNUM' in self._commands

Waiting for new SMS message...

I only receive message when python-gsmmodem is running and I'm unable to read messages that I received before...
I also tried processStoredSms() but nothing append.

Thanks

My GSM Modem doesn't support UCS-2 but HEX. I have been using a C# app, converted it to PDU and then sent used AT commands to send SMS through serial port.

This library seems more reliable but I can't seem to get this working with HEX. When I try to send like emojis the application dies.

I guess I was close but this library always tries to encode the messages as UCS-2

Am I missing something here?

Hey is this tool capable of calling a number and playing pre-recorded audio file ?

i get my number use USSD response, and get in Cyrillic char-set, but don't decode

i resolve this problem use this hack:

        try:
            msg = binascii.unhexlify(original_message).decode('utf-16-be')
            out('Use decode utf-16-be')
        except:
            msg = original_message
            out('Use decode plain')

are this hack correct?

Increase timeout when checking the PIN.
cpinResponse = lineStartingWith('+CPIN', self.write('AT+CPIN?', timeout=0.25))
original issue: faucamp#50

currently: 0.25 sec
new value: 15 sec

Ubuntu networkmanager uses 15 sec timeout:

After looking in the bowls of modem-manager, I found the line which creates this request. Adjusting the timeout (I chose 15 seconds) fixes the problem. Very simple patch attached.

This probably needs investigating as to whether the timeout for all pin checks or sets needs to be increased. I suspect that this delay is a security feature to prevent brute forcing the pin.

Hello, do you have an example of fax (class 2) usage? Thank you very much.

I am just new to this module. can any one tell me where could i find any documentation or tutorial to get me started?

Some unit tests are now broken.

I suggest to revert a locally cloned repo to the last v0.9 commit 29ca5f5, add one commit after the other and reveal which commits break the tests and why.

Anyone able to help?

I'm currently have to use the remote modem with socat command which maps the remote port to virtual local port socat pty,link=/dev/vmodem0,raw tcp:192.168.5.1:12121 but it is uncomfortable to use. A native support would be much better and more reliable.

According to pySerial docs, it should be easy to add a support for remote modems.
We only have to replace the serial.Serial() construction
self.serial = serial.Serial(port=self.port, baudrate=self.baudrate, timeout=self.timeout,*self.com_args,**self.com_kwargs)
in serial_comms.py connect() method with the alternative serial_for_url() function, which takes a lot more types of connections.

Before editing the rest of the code like adding params to modem() init functions and propagation of the needed settings to connect() method, let's resolve this:

I've successfully replaced the serial.Serial() with something like this
self.serial = serial.serial_for_url(self.port, baudrate = self.baudrate, bytesize = serial.EIGHTBITS, parity = serial.PARITY_NONE, stopbits = serial.STOPBITS_ONE, rtscts = False, xonxoff = False)
and it connects to locally connected modem as usual.

But I have trouble when I fill in an URL pointing to a remote modem
self.serial = serial.serial_for_url("socket://192.168.5.1:12121", baudrate = self.baudrate, bytesize = serial.EIGHTBITS, parity = serial.PARITY_NONE, stopbits = serial.STOPBITS_ONE, rtscts = False, xonxoff = False)

The connection timeouts because of modem not responding. The same code is working fine outside of the python-gsmmodem project. It seems it is a buffer issue or something like that. When I add printing of all the connection output, it does not output anything until I hit Ctrl+C. Then it outputs the last X lines of serial communication. Strange.

Any ideas how to debug?

Dunno why, just installs 0.11 instead of 0.12...

Find a cause of the exception and make a better fix.

original issue:
yuriykashin#1

When the GsmModem object is not instantiated with an smsReceivedCallback function, it's assigned the internal "_placeholderCallback" function.

The _handleSmsReceived method checks to see if the smsReceivedCallback function is None, and if so, ignores the processing. smsReceivedCallback is NEVER null, so processing occurs, one aspect of which is that the message is deleted after the _placeholderCallback function is called.

Suggest the if statement read:
if not "_placeholderCallback" in self.smsReceivedCallback.im_func.name:
instead of
if self.smsReceivedCallback is not None:

tried to connect the modem manually from terminal and run AT+CLAC
it return the supported command but instantly disconnected from computer and then automatically connecting again
i'm using ZTE Vodafone K3806-Z
i just bought this modem because my previous modem Wavecom Fastrack M1306B doesn't support AT+CLAC either

i know this is the problem with the modems but is there any way to bypass this AT+CLAC
i can't afford another modem :(
i mean all the use of this is just checking if AT+CSCS is supported
and some device specific settings

        if self._commands == None:
            self._commands = self.supportedCommands

        if '+CSCS' in self._commands:

Working with the sample code here: http://blog.wathmal.me/create-your-own-sms-gateway/ which uses this package, the message concatenation doesn't seem to be working.

Specifically when I use

pdu = sms.to_pdu()[0]
I get part one of the message, but if I use
pdu = sms.to_pdu()[1]
I get part 2, but if I use:
pdu = sms.to_pdu()

It doesn't concatenate. Any tips / working examples?

It is not true that every modem responds with single int value in CFUN command.

modem.py +223
cfun = int(lineStartingWith('+CFUN:', self.write('AT+CFUN?'))[7:]) # example response: +CFUN: 1

The line could be replaced with following one if you don't need to use the command.
cfun = lineStartingWith('+CFUN:', self.write('AT+CFUN?'))[7:] # example response: +CFUN: 1

I don't see that as a real issue to make pull request, though mentioning it seemed responsible.

I am trying to receive sms, using code from example.
Program connected to gsmmodem.
I receive my sms once, when I plug in new gsm modem the first time.
What could be the problem?

Hello! I trying to send long SMSs. When I send long SMS (eg. consisting of 7 PDUs) using GSM-7 coding it works fine. But when I send long SMS using UCS2 coding (even consisting of 2 PDUs) - on receiving side text is corrupted. It seems like an encoding problem, isn't it?

Source text (I trying to send this):

File		:	beacon.py - Location reporter service

GSM_CTS_PIN = 15  # NanoPi's PA3 pin
GSM_STATUS_PIN = 21  # NanoPi's PC1 pin
GSM_PWRKEY_PIN = 23  # NanoPi's PC2 pin (Active High)

This text will be encoded using UCS2 due to "\t" symbols near the beginning. I programmatically limit this text to fit it into 1 then 2 PDUs. Results on the picture:

First (correctly coded) message - source text was limited to 1 PDU (UCS2).
Second (incorrectly coded) message - same source text was limited to 2 PDUs (UCS2).

The Modem I use is SIM800C.

In case of ^RSSI and +CMGR are both in the response list handled by _handleSmsStatusReport it raises CommandError.

Example response list that raises error:

['^RSSI:3', '+CMGR: "REC UNREAD",6,203,"1320",129,"17/06/13,19:00:58+28","17/06/13,19:00:58+28",0', 'OK']

The way to reproduce:

1. run modem into idle, unhandled modem notifications ^RSSI will flow
2. do any actions to make handled notifications come
3. wait until ^RSSI and handled notifications are received at one time

Device: Huawei E171
