How do you send data from esp32 or esp8266 by wifi to mit app?

[bigplik]

Hi, I am trying for some time to send data from esp32/esp8266 to mit app by wifi and unfortunately without success.
There are some finished examples but only for one way communication, from mit app or web server (eg.ledOn/, ledOff/) to MCU.
However I didn't find any satisfied example that let to receive data from MCU (eg. analogRead in time interval) and send them to mit app inventor app.

I appreciate any advise to make that communication working.

There is a lot of information about the ESP32/ESP8266 in this Community.

BLE ESP32. Bluetooth. Send. Receive. Arduino IDE. Multitouch

Hello friends, I'll write in this topic about BLE on ESP32, send and receive text, with clock and without clock. Notify. I'll use the codes of Neil Kolban. 0.- Board D1 R32 ESP32. This is a cheap card ($ 5) with the dimensions and shape of the Arduino UNO, but with the ESP32.

I am looking for wifi data transfer from mcu to mit app, not bluetooth.
