Gsm_MsgSendText send message twice

hi @nimaltd
thank you for your useful library
when I send a message in the Gsm_UserNewMsg function with Gsm_MsgSendText any message send twice
I guess receive message doesn't delete in StartSim80xTask

for(uint8_t i=0 ;i<sizeof(Sim80x.Gsm.HaveNewMsg) ; i++)
{
if(Sim80x.Gsm.HaveNewMsg[i] > 0)
{
//Gsm_MsgGetMemoryStatus();
if(Gsm_MsgRead(Sim80x.Gsm.HaveNewMsg[i])==true)
{
osDelay(100);
Gsm_UserNewMsg(Sim80x.Gsm.MsgNumber,Sim80x.Gsm.MsgDate,Sim80x.Gsm.MsgTime,Sim80x.Gsm.Msg);
osDelay(100);
Gsm_MsgDelete(Sim80x.Gsm.HaveNewMsg[i]); /message not deleted in this line/
osDelay(100);
}
Gsm_MsgGetMemoryStatus();
Sim80x.Gsm.HaveNewMsg[i]=0;
}
}
//###########################################
if(Sim80x.Gsm.MsgUsed > 0)
{
if(Gsm_MsgRead(UnreadMsgCounter)==true)
{
Gsm_UserNewMsg(Sim80x.Gsm.MsgNumber,Sim80x.Gsm.MsgDate,Sim80x.Gsm.MsgTime,Sim80x.Gsm.Msg);
Gsm_MsgDelete(UnreadMsgCounter); /message delete in this line/
Gsm_MsgGetMemoryStatus();
}
UnreadMsgCounter++;
if(UnreadMsgCounter==150)
UnreadMsgCounter=0;
}

Extra parentheses (complie error)

Always false returning on Sim80x_SendAtCommand function

Dear nimaLtd,

thank you so much for your best lib for sim800 modules, I have some problem with Sim80x_SendAtCommand function, this function just returns false in all-time although the simcom module returns true answer and the MCU will go to UART interrupt routine and then called Sim80x_RxCallBack(),

but the SIM80x_SendAtCommand returned false value ,

can you help me, please? or send some better examples, please?

thank you so much
Best Regards

Sending data over TCP/UDP in transparent mode

This library is very wonderful, thanks
I’m trying to send binary data over TCP to a server using SIM800. I need to send binary data, without coding, non-ASCII characters indeed. Some of the data bytes can be 0x1A which coincides with the send command, doing that all data were transmitted early. Using AT+CIPSEND=< length > solves the problem because data are transmitted when the content of the buffer reaches that quantity. But this latest version, TCP-related functions removed and never touched about this.
Could you add TCP functions?

You might want to allow roaming

I'm having a hard time with the library because there is no documentation. Apart from that it seems quite complete.

I found one issue: It didn't recognize the roaming status as registered. For now I changed line 21 in gsm.c to:
if (p2 == 1 || p2 == 5)

It might be desirable to be able to configure that, but for my purposes this is the solution.

Many Greetings!
Remo

problem in FreeRTOS function in SIM800_V2

Hello and respect
If possible, share some code samples for sim800_V2. I have little experience with FreeRTOS and newbie in STM32. By the command that you said the library file was added to the code. After the program and code testing, the osKernelStart function hangs. I am a Persian user, is it possible to subscribe to another social network ID for share my code for you? part of code was important that commented under text.
use STM32F103RBT6
//**************************
Sim80x_Init(osPriorityLow);
MX_FREERTOS_Init();
osKernelStart(); // hang up on this function
//*************************
Thank you, Barati

example

Hi
Could you please add some simple examples ,how to use this library in code for FreeRTOS newbie's.

Is GSM libs only compatible with baud rate 9600?

SIM800C module is failed to work when I set the higher baud rate other than 9600.

Is this a limitation of GSM libs or anything I am missing?

sim800l can't connect??

i use sim800l with stm32f103c8 and sim can't connect to cellular network there is error in
if (gsm_command("AT+SAPBR=1,1\r\n", 90000, NULL, 0, 2, "\r\nOK\r\n", "\r\nERROR\r\n") != 1)
so pls can u help me.

My regards

I thank you from the bottom of my heart.

Please clarify this Regex

https://github.com/nimaltd/Sim800_V2/blob/5c76a909f7f69a1f3bea00b078e56c0fb0795abc/Sim80x.c#L734

Can you please provide a reference for that Regex?
I'm using Quectel which has exactly the same format for this command and it gets the number right but the date appears as 2017/05/ so I guess that's where the rest gets messed up and I don't get the msgOk flag because tmp_int32_t equals 2.

gsm_call_dial() function locks the program

Hi,

I tried the library and I can send sms properly, but when I try to make phone call, the program stucks in a way that all tasks stop working.

Here is my FreeRTOS configuration:

Here is my gsmTask:

Here is my GSMRun Task:

It sends the AT command, my phone rings, so when I debug, I see that the PC comes here (line 39 of call.c, inside gsm_call_dial() function):

Then it goes to atc_command() function and spends some time in this loop (located between line 195 & line 198 of atc.c):

Then I press resume to see where it stucks, and I see that it stucks in line 278 of heap_4.c:
configASSERT( ( pxLink->xBlockSize & xBlockAllocatedBit ) != 0 );

which is in vPortFree function.

This means the FreeRTOS somehow cannot deallocate the memory that it allocated before.

Does anyone has any idea on the solution of this problem?

Thank you.
Cheers,
Ogulcan

Where is HAL version?

Hello
Where is HAL version?

apName is null in `gsm_printf()` so it is better to use different message or remove `%s` and apName.

gsm_v5/gprs.c

Lines 7 to 11 in fa5442c

	if (apName == NULL)
	{
	gsm_printf("[GSM] gprs_setApName(%s) failed!\r\n", apName);
	return false;
	}

تاخیر بسیار زیاد در ارسال و دریافت داده با gprs

"Enable a gpio as output and open drain to connect gsm power button" means?

As per the instruction in README.md, could you please guide me what it means as below?

"Enable a gpio as output and open drain to connect gsm power button"

Do I need to connect GPIO to SIM800C VCC pin?

example for receiving messages

Hello
Can you send an example for receiving a message?

SIM800L interfacing with STM32F4

Hello,
sorry for my question that is not exactly an issue about your repo, but it seems like you're the only man on the web able to interface SIM800L with STM boards directly in HAL. I have a fairly simple project in which I need to make some HTTP operations via GPRS. My troubles come when I try to send AT commands to the GSM module because apparently I cannot get any response, after HAL_UART_Transmit(...) both polling for the answer and waiting for an interrupt HAL_UART_Receive_IT(...) don't produce any result, the module seems dead. I am sure that it is fine because if I "play" with it using an Arduino UNO there are no issues, everything is working. It is supplied via lithium battery and I also put a voltage divider for the RX input from the board as the datasheets suggests. My UART is set to send 8bit messages with no parity and one stop bit. Sorry again for my inappropriate question, hope you can give me some piece of advice.

I cannot receive incoming messages.

Hi

It doesn't go into line 360 ​​at all. And
It goes to line 351 without entering the 348th and 350th lines. I cannot read incoming messages. When I run it step by step, I see the previous messages in the array, but it never goes into the "gsm_callback_newMsg (char * number, gsm_time_t time, char * msg)" function.

Please add example for this lib

gprs MQTT semicolon error

In gsm_gprs_mqttPublish (), the at command
AT+SMPUB="topic/test send/",1,0, "{"idx":22, "value" : "%.2f; %u; 0"}"

returns an error. The module accepts a semicolon (;) as the end of the command. And no escaping\ does not work. Is it possible to fix this?

Help on simple GPRS example

Would be great if you can please provide simple example for GPRS HTTP.

Inappropriate check to process buffer leads to crash when HAL_GetTick() overflows after Approximatly 49 days

HAL_GetTick()-Sim80x.UsartRxLastTime check will fail after 49 days of MCU startup.

https://github.com/nimaltd/Sim800_V2/blob/5c76a909f7f69a1f3bea00b078e56c0fb0795abc/Sim80x.c#L1258-L1263

Solution is to change the check overall.
first of all 50ms is a constant which is not calculated or reference for a specific UART Baudrate.
STM and HAL provide a macro __HAL_UART_GET_FLAG(uarthandle,FLAG).
by checking UART_FLAG_IDLE: Idle Line detection flag it is possible to check whether a transmission is undergoing or not. how ever the downside of using this macro is that it's not portable to other MCUs.

Bug in gsm_gprs_httpRead()

I find that in atc_command function we erase rx_Buffer whit atc empty(atc); commands before copy data from rx_Bufferto to Auxiliary buffer .for debugging this issue I added a bit field like
uint8_t http_read_start :1 ;
and set it in gsm_gprs_httpRead function before sending at command and reset it at end of function
Next in atc_empty function check this bit feild like this

void atc_empty(atc_t *atc) { if(atc->http_read_start==0) { memset(atc->rxBuffer, 0, _ATC_RXSIZE); atc->rxIndex = 0; } }

use on avr microcontroler

با درود .
مهندس سپاس بابت زحماتت.
من قبلا از نسخه 2 روی stm32 استفاده کردم و خیلی هم عالی کار کرد .
منتها الان اون رو برای avr( به صورت RTOS ) پورت کردم و خطای make میده که متوجه نمیشم مشکلش کجاست .
فلش 64 مگابایت و رم 4 کیلو بایت هست(atmega64 ) .
قبلا یک برنامه بر این اساس نوشته بودم حالا ترجیح میدم از همین کتابخانه استفاده کنم . نمیدونم مشکل کمبود رم یا فلش پیش اومده یا نه .
کلا چطور میتونم از نسخه 2 روی avr استفاده کنم ؟

HardFault strtok()

Hello,
I encountered a hardfault error caused after executing strtok() from gsm_msg_read() function. strtok() is not thread-safe and since I'm using FreeRTOS this could be a problem. I was able to fix this by using strtok_r() instead of strtok(). And later, I used the custom function strtok() and it didn't cause any problems either. I also thought that this could be due to the lack of heap allocated for the task, but it seems that increasing the heap did not help me.
I don't fully understand the cause of the problem, so my solution was to use the self-written strtok() function.
It would be interesting to know if someone has come across this, or maybe my solution will help someone.
My setup: stm32F401, FreeRTOS, task heap 512 (also tried 1024).

Bug in function `bool Gsm_Ussd(char *send, char *receive)`

Hello! Could you descrive (write comments) of the API functions in your code?

In my case, I dont understand the meaning of the parameter receive in function bool Gsm_Ussd(char *send, char *receive) . I think, there is no effect of code in this function if(receive != NULL) receive = Sim80x.Gsm.Msg; because receive is local variable. Or I need to pass pointer to pointer as the parameter?

P.S. Sorry for my English.

Sim80x

Hi, your guide is very good. I found it well done and interesting.
One Question:
When you say _7) call Sim80x_Init(osPriorityLow) on your app. _ , where in the "main" i should put it to test your project?

Thanks and nice day.

Detection of DTMF tones in my SIM800L module.

I get "OK" when I send 'AT+DDET=1,1000,1,1* ' over uart .
But it doesnt seem to detect anything afterwards.
Perhaps I am doing something wrong.
Would be great to get some feedback.
