Hello! The chat bot stopped working. NodeMCU board Previously, everything worked without problems, but two days ago it stopped working. I take any of the examples, for example inlineKeyboard and get 18: 48: 17.638 -> testConnection NOK The address is pinged from the board without problems

I tried all the examples of the library, none of them worked. I changed the bot token, used different bots, it still doesn't work. Please help with the solution.

Hello Majeka, Thank you for using the library. I'm trying to replicate tour issue. As you said, there is no issue regarding the wifi connectivity between the NodeMCU and the WiFi access point, right? Some questions:

which version of the library are you using? The last pubblished is the 2.1.4 (but there is another ready to publish here - v3.0.0 branch
which version of ArduinoJson are you using?
which version of ESP32 toolchain are you using?

Could you enable the debug console, recompile and post the serial log? You can enable the debug mode by editing the file CTBotDefine.h located in Arduino\libraries\CTBot\src (Windows platform) and editing the line

// enable debugmode -> print debug data on the Serial; Zero -> debug disabled
#define CTBOT_DEBUG_MODE                 CTBOT_DEBUG_DISABLED

in

// enable debugmode -> print debug data on the Serial; Zero -> debug disabled
#define CTBOT_DEBUG_MODE                 CTBOT_DEBUG_ALL

Thanks,

Stefano

Hello! Yes, the connection to the Wi-Fi is carried out, api.telegram.org responds without problems. The library version is installed 2.1.4. Installed v3.0.0, no changes. ArduinoJson version 6.17.2 NodeMCU board with ESP8266 module Magazine on library version 3.0.0 further:

Hello, from the log, the problem is located in the CTBotSecureConnection::connect() method. The message "--->connect: Unable to connect to Telegram server" is printed out when something go wrong when the ESP8266 try to establish a connection to the telegram server. Try to:

clear the ESP8266 flash when programming the board (from Arduino, menu Tools - Erase Flash - All Flash Contents and upload the sketch one more time)
call the CTBot method useDNS(false) in the setup stage, in order to use the Telegram Server IP instead of the URL.
use an alternate access point (for example a mobile phone with an internet traffic active and configured as access point)

BTW, which is the ESP8266 toolchain version? The last from Espressif is the 2.7.4

Cheers,

Stefano

Hey! The connection is by ip, for this I wrote the designation in the output. 10:53:17.835 -> --->connect: Unable to connect to Telegram server for IP I tried 3 different access points, 2 of them are mobile Internet with different operators. Clearing memory before uploading the sketch helped nothing. Espressif version is the 2.7.4

What other tips can there be to fix this error?

I found out what the problem is, in Espressif version 2.7.4 Installed version 2.7.3 and everything started working. I do not know what was changed there, but it does not work for me on the latest version. Does everything work correctly for you on 2.7.4?

shurillu commented 3 years ago

That's very weird! I'm using the 2.7.4 without any issue. Maybe could you do another test please? Remove the Esp8266 library, do a fresh install of the 2.7.4 version and try to recompile the sketch.

Thank you for your feedback!

Cheers, Stefano

Edit: I did this procedure:

launch Arduino IDE
delete the installed ESP8266 toolchain
quit from Arduino IDE
reload Arduino IDE
fresh install of the ESP8266 2.7.4 toolchian
recompile the example with full erase of the ESP8266 flash

and still works.

majeka commented 3 years ago

After a fresh installation of version 2.7.4, everything works correctly as on 2.7.3 Very strange...

shurillu commented 3 years ago

Glad to hear that! Maybe something in the previous installation was corrupted or not updated correctly. BTW now all works correctly, thanks for the feedback! Could we close this issue?

Cheers, Stefano

majeka commented 3 years ago

Thank you very much for your support and help in solving my problem, as well as for such a library. It works great.
