Hi i used part1 it connected to esp32 wroom but if i moved away from esp32 say 5m it does not connect

can you do a video on how to save data on an external SPI chip like W25QXX

for some reason this line: Output.Text += Encoding.UTF8.GetString(recievedBytes, 0, recievedBytes.Length) + Environment.NewLine; errors on the .Length

Super clear and, for me, with the perfect level of detail. Thanks!

Hi Mo, I have been looking for a solution like this very long. It covers everything i wanted to do from the Arduino to the buttons on the website. And the real time updating with the Json system. Wonderful. Thank you so much for your contribute. Very Good. 5 Stars from me.

To install this library, type only 'websockets' in Arduino IDE library manager. There will be the usual 'ArduinoWebSockets' library by Gil Maimon, and a few others like 'Fast web sockets'. Skip them. Scroll till you get 'WebSockets' by Markus Sattler.

very informative, thank you so much

Apparently these BT permissions only work on Android 12+. For older devices you need android.permission.BLUETOOTH and FineLocation

All the information you need to get started with web sockets - neatly shrink wrapped into a 35 minute video. Excellent!

can i send two data type in one characteristic or receive it with a list or something ?

Absolutely Great, Simple and Clear Explanation.

I don't know why when I use slider I sometimes get float number instead of integer and my serial doesn't print if it's not integer. For example. From phone to ESP32: ID: 1, value: 170.5 Serial monitor: nothing. From phone to ESP32: ID: 1, value 170 Serial monitor: Id: 1 val: 170.

Fantastico job!

Do you have a video where the Bluetooth app will save the data to the esp32 that is persist after reboot of the esp32?

it works great with char1 but the app doesn't start when char2 blocks are in 😐... Thanks for this very detailed description and step by step creation

Do you know any reference about how to interpret the values in the packets?

You are one heck of a teacher. I commend you Sir.

I have some questions and solutions pls tell ms how can i ask

still Waiting you makes can save pdf to reporting 😊

Brilliant stuff!!

Great explanation

Thank you so much Mi o ni WA e ti

on my ESP32-c6 it crashes at webSocket.begin() (line78) Initializing WebSocket... Guru Meditation Error: Core 0 panic'ed (Load access fault). Exception was unhandled. Is there another way to do it without WebSocket?

I dunno what to do! Im just using a rotary with the atmega328p chip, and then I make the pull up resistor circuit + filters but the values still bounce any time.

Hello! Have you tried to connect 2 clients to 2 characteristics of one server?

Hello! Do you know if it is possible to connect 2 esp32 to 2 different characteristics of one server?

Hi would this work with the Arduino giga R1 wifi? I want to display load cell readings in digital format using BLE

Great video. Thanks!

The extension BluetoothLE is no longer available through the link. It shows "This page is obsolete" and I can't find it anywhere else to download. Can someone please help?

nc work

Thank you for this guide! I'm struggling to find the 'BluetoothLE.aix' file, as the link to download it returns "this page is obsolete", and the googles doesn't seem to know where to find it yet. Any tips?

Great tutorial! Loved the slow and steady explanation in the beginning! Felt like I didn't have to pause or go back to understand things, however at the end it felt kindda rushed and I needed to pause/go back over multiple occasions. (Still great tutorial!!)

Any thoughts what would be involved in writing an ESP32 application, that takes data from the uart, and passes it wirelessly either via bluetooth** (SPP) or via Wifi? One way communication is fine for now (RS232->ESP32->BT/Wifi - - - - > Mobile/PC) For Wifi, I imagine the ESP32 could act as a web server (TCP) and display the RS232 data, but maybe there's also a UDP way of sending the data to a PC on the same network? If the receiving application (mobile or PC) is written with the flutter framework, it could display the RS232 data with style! **I purchase some USB-bluetooth dongles (Feasycom BP102, HC-05/HC-06/CP2102 master modules, etc).. but none can connect to any android phone! For example, when a Samsung S5 tries to connect to one of the bluetooth dongles, it will stop blinking, but after a couple seconds, Android says 'Can't communicate with the FSC_BP102' or HC-05, or HC06, etc.

Супер все работает

@mothunderz Уважаемый друг! Спасибо большое за подробные и пошаговые объяснения! Могу я попросить тебя объяснить мне еще белее простую вещь - как работать с чистым HTML (то есть без JavaScript) и обработкой на сервере POST и GET запросов? На примере хотя бы одной кнопки и полей 'include'. А то я не могу понять как мне введенное пользователем время отправить и считать на сервере и сравнить с реальным... ПОЖАЛУЙСТА. Спасибо!

Just asking- is it possible to pick the time info only from any network or wifi nearby, without log in?

hello, thank you very much for your code, I'm just trying to add a function, restart on NoteOn, without success, could you give me a type of how I do this? Thank you very much!

Can u plz explain why 516>=error number, why it is 516, what is happening when is lower or higer than 516. Thank you.

Hi i am creating a device that has esp32 and the other device is Pi5 which runs android os an app can be installed in this os . Now , i need to connect my esp32 with the pi5 only . Can you guide how i could do this ? In my mind .. it is giving characterstic id call from esp32 and the app would have the same the characterstic app . If the app detects the characterstic uuid , then connect directly to esp32 . Please let me know if this is right or show a video/code on how to do this as a refernce

I am at the Point 12:22 and the App can't find the ESP32. The list doesn't open. When I search for it over Bluetooth from my phone, I can find the ESP. I did everything exactly like in the video and can't find the issue. Can anyone help me with that please? It's the ESP32-WROOM-32E

Sir, how to make LAN to WiFi convert using ESP32 and enc28j60?

Using IDE 2.3.2, sketch BLE_server, ESP dev module I get error ...Compilation error: 'init' is not a member of 'BLEDevice' Could not find ESP32 BLE Arduino, so I used🤕 these includes: BLEDevice.h BLEServer.h BLEUtils.h BLE2902.h

Can you make a tutorial on this for Android studio?

i receive an error in final code at line ''std::string pChar2_value_stdstr = pChar->getValue();'' and the error is ''error: conversion from 'String' to non-scalar type 'std::string' {aka 'std::__cxx11::basic_string<char>'} requested'' can you fix this?😓
