Already tried different baudrate, the output still the same. Thanks a lot.

hey I am using this with Arduino IDE 1.6.8 and 1.6.9 but in both of them there are two errors coming up.

1. D6 and D5 are not defined. Got to change them to 6 and 5.
2. Software Serial library in the default library folder is not matching with the Software serial that you are using. Correct me If I am wrong here.

https://www.arduino.cc/en/Reference/SoftwareSerial

I am using the default software serial library.

Your constructor:

A6lib::A6lib(int transmitPin, int receivePin) {
    A6conn = new SoftwareSerial(receivePin, transmitPin, false, 1024);
    A6conn->setTimeout(100);
}

default Softwareserial lib. takes the last argument ??

I have you faced any issue with Greek SIM (cosmote/wind)?
Never connected.

Can you send me a pic with connections?

I tried also directly with Putty Serial Connection,

I wrote that lib in the Arduino IDE. Sending works fine but I can´t receive anything. only gibberish.

First of all thank you very much for this good library, I have a problem reading SMS.
Both sms date and sms number are Ok but the message is not shown correctly, rather than the text it shows some random number and squares!
Text is simple English , is there any special decoding ?

The comments can be found there:
https://app.codacy.com/app/1technophile/OpenMQTTGateway/pullRequest?prid=1542170
If you are interested in taking them into account

Hi, thanks for this awesome library of yours. I've tried this, everything's working fine. But the only problem is that, the text messages that I send to GSM A6 wont display on the serial monitor. Do you happen to encounter this problem? Thank you.

In the example maxItems is defined to 50, it could be better to set it at startup level of the object when using the sim card memory following the result of AT+CMGD=?

Example of return from my module:
+CMGD=?
+CMGD: (1-50),(0,1,2,3,4)
OK

Mainly due to the fact that this value is proper to the sim card

Infos there:
http://www.developershome.com/sms/cmgdCommand.asp

If i text "BAL" to my service provider using a sim card in my phone i get the current balance returned to me by text, if i text the service provider using A6Lib i get a response;

New message at index: 1
2732
2019/01/04,13:51:04+00
Sorry, I didn't understand that. For information, text MENU to 2732, or visit mobile.asda.com

If i text "MENU" i get the same response. Is it possibly sending a wrong character format for the service provider to read via its automated service? - If so how and where am i best to change this

Hi,
How can I connect the A6 to a NodeMCU board? I cant seem to find any documentation....

Getunreadsmslocs() not return value.
Readsms(3) function is working.
I changed cpp file in "rec unread" to "all" but nothing.
Where am i doing wrong?
i use arduino nano with a7 module.

I'm tring to run gsm relay with A6 module and run into stability issues with A6lib. ProMicro board, SoftwareSerial.
I'm using "A6l.checkCallStatus();" function to extract "cinfo.number", so I could see who is calling before answering.
In serial monitor I got randomly scrambled charters between RING.
So far I have found two things to make it run better:

1. in A6lib.cpp change A6conn->setTimeout(100); to A6conn->setTimeout(20);
2. hold your finger on some A6 module grounded part, so some EMC isssue

Feel free to: verify, comment, help further.

when I use ir with nodeMCU it give me it is not compatible

Hello,

it seems that i can't read sms that contains special chars like ă î ș ț

getUnreadSMSLocs does not count them.

Do you have any idea why ?

Hello. Using this function
`sscanf(response.substring(respStart).c_str(), "+CMGR: "REC %s","%s",,"%s"\r\n", type, number, date);

sms.number = String(number);

sms.date = String(date);

// The rest is the message, extract it.
sms.message = response.substring(strlen(type) + strlen(number) + strlen(date) + 24, response.length() - 8);
`

I can't make out the answer
`

Hi. I have an issue with the dial.ino. it gets stuck in the blockUntilReady function.
If I invert the RX and TX lines, then it passes but no data comes to the ESP8266. Signal Strength shows some number like 6845364 and cinfo.number is blank.
How can I tell that the A6 is actually working?
I tired calling it but the call goes to voice mail. I dont have the module to connect the A6 to the serial port of my PC, so I can only use the ESP to validate.

How to use a6 module librarry with hardware serial on arduino?

Hi, Could you precise if your code let ESP connect the internet over the A6 GPRS connexion ?

Hi, how I can run the example in DEBUG mode?
I want to see all Serial.println message
thanks

Hello, I am using Arduino A6 GSM module (Ai-Thinker) and having a weird problem that I cannot resolve. After reading first incoming SMS module stops responding to further read sms commands with timeout error. I can provide dump if that helps. Please advice

Hello,
i've tested the library for a big period of time, and with esp8266 resets are quite often. They occur at initializing while in delay, or when sending SMS.
Power source is not the issue. I suspect that has something with software serial an interrupts, eg modem is sending data and esp can't capture it because is doing something else.
Do you have any improvements ? Or ideas ?

Thank you.

Great project so.

Hello, I have visited the page very often, obtaining very good results and always taking my knowledge.

Now something occurred to me and I still do not find anything concrete. My question is the following ... Is it possible to use any of the SIM modules to use the data that has the microSIM, and that way to connect to the internet, just as we do when sharing the internet with the cell phone?

I think it should be activating this function using AT command but before moving something, I prefer to make sure, besides I do not know if I have to add the WIFIesp8266 to transmit this data. Thank you and a big greeting, even if I do it before, I will not hesitate to share it with the community.

Hi
Would please provide a simple arduino sample ?

When I scan I got just those data but I know there is many other types of data when scan iBeacon with ESP32 I want to know how to get those data like signal power

Hi.
I need to pass user and password to the APN like this:
AT+CSTT="web.tmovil.cl","web","web"

but I dont seem to find how to do this.
Here is what I have tried:
retstatus=_A6l->A6command((const char *)"AT+CSTT=web.tmovil.cl,web,web", "OK", "yy", 20000, 1, NULL);
This will retrun:
Issuing command: AT+CSTT=web.tmovil.cl,web,web

If I start adding quotes to the AT part of the line it still show the same Issuing Command.

Hello guys,

can you help me find out what I did wrong and why I get this error when veryfing the example sms sketch ?

I'm using Arduino IDE 1.8.0 and now I also tried other examples and I get the same error.

What I'm doing wrong ?

Thank you.

I tried to compile the example "dial" in Arduino V1.6.13. After I got the error message

sscanf' referenced in section .text.startup' of C:\Users\BJ\AppData\Local\Temp\ccVAm20R.ltrans0.ltrans.o: defined in discarded section `.text' of libraries\A6lib-master\sscanf.cpp.o (symbol from plugin)

I searched a bit and found this one:
https://forum.repetier.com/discussion/2389/stepperwait-referenced-in-section-text-compiliation-issues

After I changed
int sscanf(const char *buf, const char *fmt, ...) {
in sscan.cpp to
int __attribute__((used)) sscanf(const char *buf, const char *fmt, ...) {
the sketch "dial" was compileable.

int getUnreadSMSLocs(int* buf, int maxItems)
{
String seqStart = "+CMGL: ";
String response = "";

// Issue the command and wait for the response.
byte status = A6command("AT+CMGL=\"REC UNREAD\"", "\xff\r\nOK\r\n", "\r\nOK\r\n", A6_CMD_TIMEOUT, 2, &response);

int seqStartLen = seqStart.length();
int responseLen = response.length();
int index, occurrences = 0;

// Start looking for the +CMGL string.
for (int i = 0; i < (responseLen - seqStartLen); i++) {
    // If we found a response and it's less than occurrences, add it.
    if (response.substring(i, i + seqStartLen) == seqStart && occurrences < maxItems) {
        // Parse the position out of the reply.
        sscanf(response.substring(i, i + 12).c_str(), "+CMGL: %u,%*s", &index);

        buf[occurrences] = index;
        occurrences++;
    }
}
return occurrences;

}
