This code let you send the method getMe and sendMessage to a telegram bot using https get and https post respectively. Using the esp_http_client example to begging and kenzanin's repository called esp-idf-telegrambot as guide I was able to achieve communication with telegram server. The certificate (that let you use https) has been change to the one in https://github.com/witnessmenow/Universal-Arduino-Telegram-Bot/blob/master/src/TelegramCertificate.h in order to communicate with the telegram server.
It work with the function esp_http_client_perform, but it has another path with the native example, but this then to crash and force the ESP32 to reboot.
Note: when you send Json to the telegram api you have to do it with this format: {"chat_id":123456789,"text":"Message to send"}
- Download the latest realase with
git clone https://github.com/antusystem/esp-idf-telegram-bot.git - Go to the folder cd ../esp-idf-telegram-bot.git
- Build the menuconfig to make the respective changes to your computer
- If you are using Eclipse, once it is added as a project, in its propierties check C/C++ Build > Environment check the IDF_PATH if it is correct
- Compile
make clean - Compile
make all
It should not indicate any error following this steps.
You have to configurate the next defines for it to work:
- ESP_WIFI_SSID: you have to introduce your ssid to connect to your wifi network.
- ESP_WIFI_PASS: you have to wrtie your ssid password to connect to your wifi network.
- API_KEY: the API key that Bot Father already gave you when you create your bot.
- chat_ID1: if you know the name of a public chat write it in this define.
- chat_ID2: to write yo any type of chat, write its ID in here. This one work for both private and public groups.
- LED: configure if you want to turn on a led connected to a pin.
With this it should work fine and write to the chat (personal or to a group) in the id.
Check de IDFPATH in the configurations of the proyect
- Last compile: January 11th, 2021.
- Last test: January 11th, 2021.
- Last compile espidf version: v4.2
- Read and organize the response Json (probably using Cjson).
- Discard the native examples from the master branch and create separe functions for getMe and sendMessage.
- Determinate what other type of data can be send with the esp32 to make the code.
