Callback queries do not work. The reason is that m_inlineKeyboard is not set

Issue can be resolved by changing (in AsyncTelegram.h)

inline void sendMessage(const TBMessage &msg, const char* message, InlineKeyboard &keyboard)
{
    return sendMessage(msg, message, keyboard.getJSON());
}

to

inline void sendMessage(const TBMessage &msg, const char* message, InlineKeyboard &keyboard)
{
    m_inlineKeyboard = keyboard;
    return sendMessage(msg, message, keyboard.getJSON());
}

How to authorize by chat id?
How to make the bot answer only one chat id?

Hi,
congratulations for your library, I find it much lighter than the others, and it was easy to use it and communicate with my bot. I have some questions for you about using the finger print:

1. if I declare this in setup ():

// Set the Telegram bot properies
// api.telegram.org
uint8_t telegramFingerprint [20] = { 0xBB, 0xDC, 0x45, 0x2A, 0x07, 0xE3, 0x4A, 0x71, 0x33, 0x40, 0x32, 0xDA, 0xBE, 0x81, 0xF7, 0x72, 0x6F, 0x4A, 0x2B, 0x6B }; // https://www.grc.com/fingerprints.htm
myBot.setFingerprint(telegramFingerprint);
myBot.updateFingerPrint();
myBot.setUpdateTime(2000);
myBot.setTelegramToken(token);
myBot.begin();

is my connection with the telegram server already encrypted or do I have to do something else?

2. how myBot.updateFingerPrint () works from the documentation I can't understand. Do you have any examples?

Thank you

Thanks for library! One problem. sendToChannel works only one time.
`void loop()
.....
if ((millis() - temp_start) > 30000)
{
temp_start = millis();
tm* _tm;
time_t utcTime = time(NULL);
_tm = localtime(&utcTime);

    String str;
    char buf[100];
    strftime(buf, sizeof(buf), "This is esp32 message at:  %A, %B %d %Y %H:%M:%S", _tm);
    str = buf;
    Serial.println(str); //see it every 30 sec
    myBot.sendToChannel(channel_id, str, true);//see it only first time in my channel and in serial log
}

....

Hi,

Since sendToGroup is marked deprecated,
what is the new (or future) way to send messages to group?

Thank you.

It is not good to use the wifi check in the library, it creates an external dependency.
I have also verified that sometimes the Wi-Fi is active, but the connection with telegram has been lost, due to errors, low speed, heating of the chip, etc.
I think it is better to use the checkConnection () function.

I am using your scratch and it works very well, I only found 2 small problems:

1. sometimes it loses the connection and is no longer reachable by telegram. Neither with incoming and outgoing messages.
2. if I send more messages they are lost. I have seen that if I already send 2 messages the second does not arrive. For this problem I have built a FIFO queue at home, and I use it as a layer in the "sendMessage" method to insert the messages and in the "httpPostTask" to do the get of the messages and subsequent sending.

Do you think the change I inserted in point 2 can cause a loss of connection described in point 1?

My objective was to have the ESP-32 camera send me a photo to Telegram every 10min, from 6h00 to 20h. To save energy and have more control over time and alarms, I added a DS3231 to my project. With other libraries and uploading methods, it was either not possible to send full resolution photos or it would fail after a while. It is crucial to have a good wifi connection and for that I upgraded the antenna (I have 4 units and pcb antenna gave me poor range in all of them), but it's also important to have a good power supply (good filtering to prevent artifacts in photos and high current delivery capability to maintain wifi communication).

https://github.com/FBMinis/DS3231-Alarm-ESP32-Cam-Telegram-Bot

Thank you for your work.

Add the possibility to append some parameter to the telegram sendMessage method.

A method with a signature like this could be helpful:

void sendMessage(const TBMessage &msg, const char* message, String booleanParameter = "", bool parameterValue);

The method could be even more generic using a linked list of a custom type and in the custom type we can specify the parameter name and value.

As an example I need to send a message without notification sound so I need to set the disable_notification parameter to true.

Hi! Is it possible to use this library without connection to WIFI? I have SIM800 onboard (T-CALL) and there is no WIFI newtorks nearby. I use TinyGSM.

How to check connection status other than begin() and how to stop connection to telegram ?

Dear Tolentino,
first of all Congratulation for this amazing delevopment.

I would like your help, if is possible.
Since you release new version I can't get make code working.
Initially let's inform you my setup:
ESP8266 nodeMCU and Wemos D1
ESP8266 Core = 2.7.4
ArduinoJson version: 6.17.1
AsyncTelegram version 1.0.8 (with a small change as described below)

In order to have the version 1.0.8 working I have to increase the Buffer Size as indicated in the issue: #6
So, in my library I have:
DynamicJsonDocument doc(BUFFER_BIG);

I have attached the code and also the library I am using, in order to keep same scenario.

test_AsyncTelegram.zip

As soon as I update your library for last version, inline keyboard is not available anymore, even change the code as before.

To test:
You should inform your userId, because I have in this code is a function to validate the user who will interact with the bot.

int userId[] = {2360873, 0, 0, 0, 0, 0}; //--> Should include your UserID ==> send message to @myidbot

Thanks in Advance.

Edson

Both the keyboard example not working. Only replykeboard is working. when pressing any button on inline keboard nothing happens.

Hello,
I'm having a little problem using the library you've made. I have a sketch that is doing a lot of serial reading, three devices at 2400 baud and one at 9600. Of course I have to wait for answer for every command i send to the devices. For that i'm using vTaskDelay (not delay).
In certain cases, the sketch has to send messages. Some of those messages gets lost. They don't arrive at all.
The setUpdateTime was set at 2000 and I've changed it to 1000...same problem. I've tried to add a vTaskDelay after sendToUser...same problem. I'm using String variable to compose my message.

Do you have any advice for me? Thank you!

I am trying to expand ESP32-CAM.ino for my needs. An image request by /takeFoto command from my Bot works great. But when I trying to initiate capturing and sending an image by ESP itself by executing code string
myBot.sendPhotoByFile(chat_id, myFile, filesystem);
on pushing a button, then 50:50 an image will be sent and receied by my Bot OR one of two next exceptions will be occured and then ESP reboots:

Hi,

This issue report started as a comment here :)

I just flashed the dev branch to my ESP32,
I will leave it to run in debug mode and capture its log to a file - I will report if the problem occurs.

From a 5 minutes test, the memory seems stable with:
Heap: 176092, MaxFree: 113792, Task stack: 6576

Thanks for all the great work on the dev branch!
Arad.

I modified the inlinekeyboard example and my bot is now working with messages of type
MessageText
MessageQuery
MessageContact

As I was testing my bot I accidentally send a GIF from the client to the bot and the ESP crashed and got stuck in a bootloop. After getting the (GIF-)messages with a Pi Bot script the ESP was working again. I then testet image video and sticker messages and they are ignored by my code as expected. Only GIFs run the ESP into a bootloop.

Here is my serial output:

Look here, I found reason and solution.

Isn't channel ID required?

Among the commands I am sending to my telegram-controlled bot device, there is the /reboot to ask the device to restart. The problem is that as soon as the device returns ready, it will get another /reboot command and so on forever.

Is there a way to "flush" the message queue before rebooting the device (or upon starting)?

Good Morning! I've a big trouble 'cause i can't compiling any sketch in Arduino.
Any time i'm compiling a sketch with this library i've got the error:

C:\Users\Utente\Documents\Arduino\libraries\AsyncTelegram\src/AsyncTelegram.h:191:5: error: 'BearSSL' does not name a type
BearSSL::WiFiClientSecure telegramClient;
^
exit status 1

i've this library installed:
ArduinoJson 6.17.2
AsyncTelegram 1.0.8

I don't know how to resolve. Thanks in advance for the help and sorry for my mistake

Use of "sizeof" throughout code to check for string lengths is incorrect.
suggest as a replacement:

bool isEmptyString(const char* str) {
return !str || !str[0];
}

bool isEmptyString(const String& str) {
return (str.length() == 0);
}

hello! A good library! The only question is, if you load the sketch from the echo example, the transmission of the characters -,*,. does not work, and if you write any other character, for example, 567, everything works. I use esp8266 nodemcu, board version 2.7.4, json 6.18.0. Sorry for my English))

When I'm trying to add 11-th button to the Reply Keyboard, it stops sending messages.

In master/src/AsyncTelegram.cpp: void AsyncTelegram::sendMessage
It turned out that 512 is not enough:

if (keyboard.length() != 0) {
    DynamicJsonDocument doc(512);
    deserializeJson(doc, keyboard);
    JsonObject myKeyb = doc.as<JsonObject>();
    root["reply_markup"] = myKeyb;
}

If I change DynamicJsonDocument doc(512); to DynamicJsonDocument doc(1024); it works fine.
Maybe it should be changed to BUFFER_BIG, or 1024 is enough.
Have a good day.

i'm trying to make some kind of user authentication and the only possible way to track a user is by chat id, but i couldn't see any public method or attribute in the header file referring to the chat id for an incoming message, is it not possible or i didn't notice it ?

I cannot use this construct:

myBot.sendToUser(userid, "test");

How to use it correctly?
If I replace "test" with a variable of type string - Everything works.
