[SOLVED] Arduino and esp as telemetry without using library


is there any way to send data without using arduino libraries?

Setting Arduino+ESP8266

Greetings, you may send AT commands to the ESP8266 using the arduino’s serial port.

Once you can make that both devices can interact, implement a POST requests that fits our REST API implementation.

Also, if you need some reference, you can see some examples at our help center.



Thank you. Now my project is working without using libraries.
