How to send data from esp32 to android app

Senzu tv 4 digit code
I have an ESP32 module. I want to send data to it using an Android app. I tried using http but the delay is big especially since I want to send about 20 values per second with a delay between 50 to 100 ms. So I am looking for a better way to do it. I am trying to send a Time of Flight sensor (VL53L0X) data, which is integer through ESP32 board via bluetooth to the android app, that I am developing in Android Studio, but I am not able to connect to the board for some reason.

Nissan m226esp32 arduino android ble example. There are so many examples for ESP32 bluetooth servers but I could not find an example code to send data from Android app to ESP32 Bluetooth server so I made one. ESP32 code is in bluetooth_android_esp32. I made it on PlatformIO. You can just copy and code in Arduino as well. In our example, we use two different characteristics, TX and RX under the overarching "service" to send data to and receive data from a client (Android device) via these two channels. The ESP32 (acting as the server) "notifies" the client via the TX characteristic UUID and data is sent to the ESP32 and received via the RX characteristic UUID.

This tutorial describes how to implement IoT Push notifications using Arduino and Firebase.Using IoT push notifications, we can send notifications to other devices. In this case, we want to send an IoT push notifications from a smart object (like Arduino MKR1000) to a mobile smartphone (i.e. Android smartphone). Sep 19, 2017 · Hence the android app should be made dynamic enough to get the ESP32 IP automatically and send the angle input to servo regardless whatever IP ESP32 gets… Given below is the architecture diagram for this approach. Architecture for Remote servo using Android app (credit : siva) How are we going to do this: Broadcast, Listen,decipher IP
