Connection problem with ESP8266 2.5.0 library and Arduino IDE 1.8.9 #118

Open array81 opened 5 years ago

array81 commented 5 years ago

If I try to compile my code with ESP8266 2.5.0 (stable) library and Arduino IDE 1.8.9 I get problem on connection to server.

GET Update Messages [BOT]Connecting to server [BOT]Conection error Received empty string in response!

I just have try to use HTTPSRedirect, the result is the same.

Has the same issue. I used debug mode and found WiFiClientSecure client failed to connect. I tried to replace it with unsecure and had some response from telegram nginx. So issue is nearby this library. Currently I still don't have working solution

witnessmenow commented 5 years ago

Use Wificlientsecure and set client.setInescure(); in your setup

Use Wificlientsecure and set client.setInescure(); in your setup …

Not working with this solution. Got an error. 'class BearSSL::WiFiClientSecure' has no member named 'setInescure'

I managed to fix it by downgrading ESP8266 to version 2.4.2.
Thanks anyway

witnessmenow commented 5 years ago

setInsecure() ,sorry I spelled it wrong

I am using esp8266 core 2.5.2. It works well by forcing the use of the (deprecated) axTLS client, not the current BearSSL client. With axTLS the performance for core 2.5.2 is similar to that of core 2.4.2 (more heap and faster than with BearSSL). And no need for client.setinsecure() by the way. See https://github.com/esp8266/Arduino/blob/master/libraries/ESP8266WiFi/examples/HTTPSRequestAxTLS/HTTPSRequestAxTLS.ino

consolacion commented 4 years ago

client.setInsecure();

Thank you. Suddenly it is all working

r-ryabyy commented 4 years ago

I have used the suggestion from @sanderkob - using axTLS, but probably better to update the code with newer libraries, since it seems this one can be deprecated and disbled soon, right ?

CyborgAndy commented 4 years ago

Thank you @sanderkob

sanderkob commented 4 years ago

It appears my workaround using (deprecated) axTLS does not work anymore, perhaps Telegram ended TLS 1.1 support? Anyway, I am now running succesfully with BearSSL and client.setInsecure()

CyborgAndy commented 4 years ago

Yes, you are right. Last week your workaround is still worked. But it is no longer working. Now I am using BearSSL and client.setFingerprint(). I got telegram api site fingerprint from https://www.grc.com/fingerprints.htm

array81 commented 4 years ago

I cannot understand how get the fingerprint.

CyborgAndy commented 4 years ago

On the site https://www.grc.com/fingerprints.htm in section "Custom Site Fingerprinting" enter api.telegram.org in textbox and press button "Fingerprint Site". You will get "Security Certificate's Authentic Fingerprint" such as "BB:DC:45:2A:07:E3:4A:71:33:40:32:DA:BE:81:F7:72:6F:4A:2B:6B". Then paste this fingerprint as uint_8 array in your skecth const uint8_t fingerprint[20] = { 0xBB, 0xDC, 0x45, 0x2A, 0x07, 0xE3, 0x4A, 0x71, 0x33, 0x40, 0x32, 0xDA, 0xBE, 0x81, 0xF7, 0x72, 0x6F, 0x4A, 0x2B, 0x6B }; Use client.setFingerprint(fingerprint); in setup block.

morrowwm commented 4 years ago

Thank you for the solution CyborgAndy. Adding those two lines:

const uint8_t fingerprint[20] = { 0xBB, 0xDC, 0x45, 0x2A, 0x07, 0xE3, 0x4A, 0x71, 0x33, 0x40, 0x32, 0xDA, 0xBE, 0x81, 0xF7, 0x72, 0x6F, 0x4A, 0x2B, 0x6B };
...
client.setFingerprint(fingerprint); in setup block.

has my bot working again.

javierferwolf commented 4 years ago

hi @morrowwm and in relation to the client parameter "UniversalTelegramBot bot(BOTtoken, client); " What should be done? change "client" to fingerprint? and WiFiClientSecure client; to WiFiClientSecure fingerprint;
sorry for my ignorance but I don't know how to add this solution!

morrowwm commented 4 years ago

You might post the code you are trying to fix. In general though: put this line

const uint8_t fingerprint[20] = { 0xBB, 0xDC, 0x45, 0x2A, 0x07, 0xE3, 0x4A, 0x71, 0x33, 0x40, 0x32, 0xDA, 0xBE, 0x81, 0xF7, 0x72, 0x6F, 0x4A, 0x2B, 0x6B };

somewhere in the preamble of your sketch, and the second: client.setFingerprint(fingerprint); near the bottom of the setup section

javierferwolf commented 4 years ago

@morrowwm hi thank you for your answer ther code simple

include

include

include

// Initialize Wifi connection to the router char ssid[] = "xxxxx"; // your network SSID (name) char password[] = "xxxxx"; // your network key

// Initialize Telegram BOT

define BOTtoken "xxxxxx" // your Bot Token (Get from Botfather)

WiFiClientSecure client; UniversalTelegramBot bot(BOTtoken, client);

int Bot_mtbs = 1000; //mean time between scan messages long Bot_lasttime; //last time messages' scan has been done bool Start = false;

const int ledPin = 13; int ledStatus = 0;

void handleNewMessages(int numNewMessages) { Serial.println("handleNewMessages"); Serial.println(String(numNewMessages));

for (int i=0; i<numNewMessages; i++) { String chat_id = String(bot.messages[i].chat_id); String text = bot.messages[i].text;

String from_name = bot.messages[i].from_name;
if (from_name == "") from_name = "Guest";

if (text == "/ledon") {
  digitalWrite(ledPin, HIGH);   // turn the LED on (HIGH is the voltage level)
  ledStatus = 1;
  bot.sendMessage(chat_id, "Led is ON", "");
}

if (text == "/ledoff") {
  ledStatus = 0;
  digitalWrite(ledPin, LOW);    // turn the LED off (LOW is the voltage level)
  bot.sendMessage(chat_id, "Led is OFF", "");
}

if (text == "/status") {
  if(ledStatus){
    bot.sendMessage(chat_id, "Led is ON", "");
  } else {
    bot.sendMessage(chat_id, "Led is OFF", "");
  }
}

if (text == "/start") {
  String welcome = "Welcome to Universal Arduino Telegram Bot library, " + from_name + ".\n";
  welcome += "This is Flash Led Bot example.\n\n";
  welcome += "/ledon : to switch the Led ON\n";
  welcome += "/ledoff : to switch the Led OFF\n";
  welcome += "/status : Returns current status of LED\n";
  bot.sendMessage(chat_id, welcome, "Markdown");
}

} }

void setup() { Serial.begin(115200);

// Set WiFi to station mode and disconnect from an AP if it was Previously // connected WiFi.mode(WIFI_STA); WiFi.disconnect(); delay(100); client.setInsecure(); // attempt to connect to Wifi network: Serial.print("Connecting Wifi: "); Serial.println(ssid); WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) { Serial.print("."); delay(500); }

Serial.println(""); Serial.println("WiFi connected"); Serial.print("IP address: "); Serial.println(WiFi.localIP());

pinMode(ledPin, OUTPUT); // initialize digital ledPin as an output. delay(10); digitalWrite(ledPin, LOW); // initialize pin as off }

void loop() { if (millis() > Bot_lasttime + Bot_mtbs) { int numNewMessages = bot.getUpdates(bot.last_message_received + 1);

while(numNewMessages) {
  Serial.println("got response");
  handleNewMessages(numNewMessages);
  numNewMessages = bot.getUpdates(bot.last_message_received + 1);
}

Bot_lasttime = millis();

} }

the error: exit status 1 'class axTLS::WiFiClientSecure' has no member named 'setInsecure'

Here is your code with the two lines added, as a text file. It compiled for me.

javierferwolf commented 4 years ago

@morrowwm thank you for your help and answer!! but forget to mention, that the version of my core 2.4.2 and i got the error 'class axTLS::WiFiClientSecure' has no member named 'setInsecure' I added BearSSL::WiFiClientSecure client; and compiles normal, but when loading the code in ESP8266 It works in the first cycle, then no longer responds and does not work!

morrowwm commented 4 years ago

I am using core 2.5.0
