Good morning,
I am trying to repeat a classroom exercise from two years ago.
Perhaps, someone here might know what to do about the following.
Test 1)
In 2019 the EchoBot example worked using TelegramBot library and MKR1000.
I just tried and it no longer works, since I see no response or "echo" in Serial Monitor or Telegram app.
I've uploaded the certificate api.telegram.org:443
ArduinoJson library is 5.x
Test 2)
Then I tried UniversalTelegramBot library and it also doesn't work!
Certificate is part of source code.
ArduinoJson library is 6.x
#define TELEGRAM_DEBUG 1
output is this:
WiFi connected
IP address:
192.168.137.13
GET Update Messages
[BOT]Connecting to server
[BOT]Conection error
Received empty string in response!
Test 3)
I am fairly sure that the bot itself is working.
/setprivacy is disabled
We can do getUpdates and sendMessage in a browser window, like so:
https://api.telegram.org/bot1793289431:AAEvBHq8ZYQPUBRxsWsUw5uRjEZO85-jdNg/getUpdates
This message HHHIIII is actually the bot sending a message.
It appears in the Telegram phone app, but not in getUpdates within the browser.
Only the messages that I send from my phone app to the bot appear in the browser.
I don't know if this is how it should be.
P.s. secret token is just for testing
