Sending messages

[gravedigger21]

Hi! I continue to deal with your library and faced the fact that I can not send a message to the telegram when any events occur. For example, write the following code: void loop() { TBMessage msg; if(digitalRead(button)==HIGH) myBot.sendMessage(msg, " button=1"); } but nothing comes in telegram. What am I doing wrong? At the same time, there is a connection with telegram.

Hi @gravedigger21 I'm sorry for late reply, but i'm very busy in these days.

In the examples included in library, the bot send a message to user as a reply, so the struct TBMessage msg is already valorized with all necessary data.

In order to be able to send directly a message to user (or to groups), you need to know the ID in advance. For example in echoBot.ino you can find these lines of code:

  // Send a message to specific user who has started your bot
  // Target user can find it's own userid with the bot @JsonDumpBot
  // https://t.me/JsonDumpBot
  int64_t userid = 123456789;  
  myBot.sendTo(userid, welcome_msg);

With your sample code it will be:

// https://t.me/JsonDumpBot
int64_t userid = 123456789;  
.....
void loop() { 
  if(digitalRead(button)==HIGH) {    
    myBot.sendTo(userid, " button=1"); 
  }
}

You could use also the sendMessage() method, but fitting the msg struct with the ID, but I think sendTo() is more "clear":

void loop() { 
  if(digitalRead(button)==HIGH) {
     TBMessage msg;
     msg.chatId = 123456789;
     myBot.sendMessage(msg, " button=1"); 
  }
}
