Good Morning
Thank you for the wonderful code. Must have taken you some time to write all that.

I really want to use your library however I need to be able to receive sms and parse.

Do you foresee this feature being available soon?

Thanks again for your hard work
Rob

Does this library support parsing multi-line responses? I'm trying to retrieve GNSS info from a U-Blox SARA R5.

TX-->AT+UGGSA?

RX-->+UGGSA: 1,$GNGSA,A,1,18,29,28,,,,,,,,,,11.16,7.03,8.672C
RX-->$GNGSA,A,1,86,,,,,,,,,,,,11.16,7.03,8.672A
RX-->
RX-->OK

The response puts each GSA string on a new line, so using await modem.RawCommandWithResponseAsync("AT+UGGSA?","");, I'm only able to see the first line of the response.

Do you have plan add record incomming call function???
Or any idea to do it

First, thank you for awesome lib.

My question is how can I send sms with the delivery report. Someone on internet said that we need to setup modem by send the 2 commands:
AT+CNMI=2,1,0,1,0
AT+CSMP=49,167,0,0

I tried, but not success.

Is this supported? (concatenation of sms over 160 ch)

Hi all!
How to Make a Phone Call and detect when phone is answered or rejected...?

Hi
I have been developing a raspberry pi powered sensor. I am just adding the SIM7600G-H 4G HAT to the device. I started off using the standard serial ports but then came across your project and the implementation of pipes. I have taken a copy of the library and changed my code to run with the pipes. During the process I have added commands for the SIMCOM 7600 as well as some standard AT Commands. I have also added extra information to the SignalQuality including decibels. Also I am using UnitsNet for anything like decibels or voltages.

Is this something you would be interested in me providing a pull request for?

Lib have a error hang Stream.Write async if COM can't write data, any way to fix it

this is code make problem

protected async Task WriteAsync(string text, CancellationToken cancellationToken = default)
        {
            
            Console.WriteLine($"write {text}");

            byte[] buffer = Encoding.UTF8.GetBytes(text);
            await stream.WriteAsync(buffer, 0, buffer.Length, cancellationToken); //hang, can't stop
            Console.WriteLine($"flush {text}");
            await stream.FlushAsync(cancellationToken);
            Console.WriteLine($"write {text} ok");

        }

I run in another Task, can't hang by UI, can you check it

What about
Number = number.TrimStart('+');

In my case in Poland it doesn't work when plus is trimmed from phoneNumber.
It's ok when this line looks like this

Number = number;

BTW. it's great library, thanks for your work.

The encoding table (Gsm7) is not correctly accounting for LF/CR ( \n and \r ) and I suppose escape:

It should be:

{ Gsm7Extension.Default, "@£$¥èéùìòÇ\nØø\rÅåΔ_ΦΓΛΩΠΨΣΘΞ\x1bÆæßÉ !\"#¤%&'()*+,-./0123456789:;<=>?¡ABCDEFGHIJKLMNOPQRSTUVWXYZÄÖÑܧ¿abcdefghijklmnopqrstuvwxyzäöñüà" },

#43

Thanks for the library!

Hi,
I could send SMS with Telit xe910 Terminal using ATLib v7.0.0-RC2 via "Text mode", but in latest release v7.0.0 there is no "Text mode" anymore. I tried to send SMS using PDU mode but either process fails with CMS 301 / CMS 304 errors or it pretends as if SMS is sent, giving a CMGS response with no error, but does not send any SMS.

I tried both GSM7 and UCS2 character set but neither first nor second set works. I would be glad if "Text mode" functionalty exists in new releases.
Kind Regards

Hello,

Is it planned to add support for commands related to LTE? Like on/off, switch between 4G/3G/etc.

Task.Factory.StartNew with flag LongRunning will create new Task and run in new Thread (not run in ThreadPool)
But you use async await without SynchronizationContext will make ReadPipeAsync run in ThreadPool after await if await another task run in different thread.

In current, it work ok (maybe not) because PipeReader.ReadAsync not in the case (depends on input stream).
It may not work in the future if the library changes or modifies the code or specific stream input, so please keep this in mind if you modify the code or update the library.

class CustomStream : MemoryStream
{
    public override async ValueTask<int> ReadAsync(Memory<byte> buffer, CancellationToken cancellationToken = default)
    {
        await Task.Delay(10, cancellationToken);
        return await base.ReadAsync(buffer, cancellationToken);
    }
}
class Program
{
    static async Task Main(string[] args)
    {
        Stream _stream = new CustomStream();
        AtReader atReader = new AtReader(_stream);
        atReader.Open();
        Console.ReadLine();
    }
}

Suggested
Install Nito.AsyncEx.Context

reader = Task.Factory.StartNew(
    () => AsyncContext.Run(() => ReadPipeAsync(pipe, cancellationTokenSource.Token)), 
    TaskCreationOptions.LongRunning
);

I have Huawei and Wavecom M1306B. Do you have any idea how to set the library to make it work with those modems? Or you have generic custom settings to achieve that purpose?

Hi,
we are evaluating your library to communicate with Telit xe910 famiy GSM terminals. Time to time we need to soft reset GSM terminal via ATZ and/or AT&Fxxx (Set To Factory Defined Configuration) commands since terminal may hang and can't turn back to normal status due to several reasons. I would be glad if Telit modules are added to supported modems and soft reset + set to factory defined configuration AT commands are added to supported AT commands
Kind Regards

Dear, I have Huawei e303 modem and i already able to use this library to send sms with this device, but now i have a problem sending Arabic language sms, i searched about it and found that it is a coding schema issue, i can send Arabic sms by another method but not with this library.
my device can support ("GSM", "IRA", "UCS2") character sets
so could you please explain for me how to implement the UCS2 coding schema for sending such type of sms using this library
thank you in advance.
