Messages not sent

Hi Tolentino. Had to reinstall my whole development computer so I went straight to the new 2.02 Arduino IDE, downloaded latest board definitions for esp8266/esp32, AsyncTelegram2 and wifimanager (downloaded directly from library and board managers)

This example is almost the same as one we debugged time ago for another issue, but now if I send a message from Telegram, its received by the board but the reply never reaches Telegram.

I'm lost, because this example is a subset of a full program that used to work, and now every old evolution of it does the same.

here is the code:

`

include

include

// Timezone definition

define MYTZ "UTC+3" //timezone https://sites.google.com/a/usapiens.com/opnode/time-zones

include //https://github.com/tzapu/WiFiManager

ifdef ESP8266

BearSSL::WiFiClientSecure client; BearSSL::Session session; BearSSL::X509List certificate(telegram_cert);

elif defined(ESP32)

include

WiFiClientSecure client;

endif

AsyncTelegram2 myBot(client); // Telegram BOT Token (Get from Botfather) const char* token = "edited"; // Telegram token

define nombrecamara "Test base Telegram" //para OTA y Wi-Fi

int64_t userid =edited;

void setup() { Serial.begin(115200); Serial.println(); Serial.println("Arrancando..."); delay(50); String message = ""; //variable local

// inicio de configuracion wifi WiFi.mode(WIFI_STA); WiFi.hostname(nombrecamara); WiFiManager wm; //WiFiManager local initialization wm.setTimeout(60); wm.autoConnect(nombrecamara); // fin configuracion wifi

ifdef ESP8266

// Sync time with NTP, to check properly Telegram certificate configTime(MYTZ, "time.google.com", "time.windows.com", "pool.ntp.org"); time_t now = time(nullptr); //Set certficate, session and some other base client properies client.setSession(&session); client.setTrustAnchors(&certificate); client.setBufferSizes(1024, 1024);

elif defined(ESP32)

// Sync time with NTP configTzTime(MYTZ, "time.google.com", "time.windows.com", "pool.ntp.org");

if USE_CLIENTSSL == false

client.setCACert(telegram_cert);

endif

endif

// Set the Telegram bot properies myBot.setUpdateTime(2000); myBot.setTelegramToken(token);

// Check if all things are ok Serial.print("\nTest Telegram connection... "); myBot.begin() ? Serial.println("OK") : Serial.println("NOK");

Serial.print("Bot name: @"); Serial.println(myBot.getBotName());

message = "ARRANQUE MONITOR: "; message += nombrecamara; message += "\n"; message = "AYUDA: Ingresa /ayuda para obtener la lista de comandos"; message += "\n"; despachar(message); Serial.print("ARRANQUE MONITOR: "); Serial.println(nombrecamara); }

void loop() { String msgText = ""; TBMessage msg; // hay mensajes de Telegram? if (myBot.getNewMessage(msg)) { msgText = msg.text; Serial.print("texto: "); Serial.println(msgText); if (msgText.startsWith("/config")) msgText = confi(); if (despachar(msgText)) Serial.println("Mensaje enviado correctamente"); msgText = ""; }

} // FIN DEL PROGRAMA

// return true if message is successful delivered bool despachar(String& theMessage) { TBMessage msg; msg.sender.id = userid; return myBot.sendMessage(msg, theMessage); }

String confi() { String message = "CONFIGURACIÓN: "; message += nombrecamara; //normally is a variable message += "\n"; message += "\n"; message += "La frecuencia de las notificaciones es de: "; message += 100; //normally is a variable message += " horas"; message += "\n"; message += "La alarma de baja temperatura esta configurada en: "; message += 2; //normally is a variable message += "°C"; message += "\n"; message += "La alarma de alta temperatura esta configurada en: "; message += 30; //normally is a variable message += "°C"; message += "\n"; message += "La frecuencia de las alarmas es de: "; message += 10; //normally is a variable message += " minutos"; message += "\n"; return message; }

`

On the serial monitor I only get the acknowledgement of the message received, but nothing goes back to Telegram.

Tried also adding the bot to a group as admin and I get the same debug:

[E][AsyncTelegram2.cpp:207] getUpdates(): {"ok":false,"error_code":400,"description":"Bad Request: chat not found"}

Hi @pablopeu, I'm sorry for the big late reply, but I've been very busy in recent months.

Do you still have this problem or did you manage to solve it? The problem is that you are using msg.sender.id instead of msg.chatId probably due to some old example forgotten somewhere.

The msg.sender.id property is indicative of the user who sent the message (to which you may want reply), but the recipient of the outgoing message must be indicated with the msg.chatId property. This is necessary because in this way the library can handle "normal" users and groups in the same way and the bot can send messages to both (the only thing that changes between a group and a user is the negative id in case of groups)

However, if you need to send a message to a specific user or group it is preferable to use the method

sendTo(chatid/userid, message)

so you don't have to make intermediate copies of the variables.

Hi Tolentino, thanks for the reply. It puzzled me for a long time, but this last weekend I was commited to solve it, so again I went to study your examples and figured out the sendTo(chatid/userid, message) was theway to go, made the slight modifications in the code and all went as expected.

I do have a new puzzle regarding asynctelegram2/thingspeak library but thats for a new post once I can write a good example case.

Thanks again for your help and the work you do with the library and its support
