connect 2 ESP32 (espressif) via BT to a third ESP32 that would use wifi.

Have good knowledge on Arduino to build any kind of Digital Device or IoT Device to send and receive any kind of sensors data or processed data to the web server by using Wifi. I can work on ESP32 if you send me the hardware board to my address. Have more than 15 years of experience on Digital Electronics .

Hi! consider this job done, I'm expert in ESP32 and have more than five ESP32 modules are here with me for testing purpose, I've already done wifi and BLE communication work with ESP32, can you please share some details? 1. what type of serial data to receive and process? in hex or simple ascii strings form? 2. what data to extract? 3. where to send data from wifi? to some online server , cloud, DB or somewhere else? Thanks. Farrukh

Using esp32 in this project may be not the good option as these devices share the radio hardware for both BLE and WiFi. When esp32 connects to WiFi, it often drops BLE connection and verse vise. May be the better approach for you is using HM-10. This is cheap device that can read data from serial and send to BLE. Still need to investigate/test but the topology may be something like this: - 2 HM-10 - 1 HM-10 + ESP32 or ESP8266 In that arrangement, we will use ESP32 or ESP8266 wifi function only. For the LCD, a cheap 16x02 LCD with a small 1 wire adapter is good enough for this project. The LCD is connected to the adapter (mounted at the back of the LCD) and then connect to the ESP via only 1 pin. Pls chat if you have any question. FYI... there are some effort to make ESP32 to work with multiple BLE and WiFi. Not tested yet but it can be considered as 1 option. For the other 2 - either ESP32 or HM10 can be used to read serial data and send to the 3rd.

We are a 14 year old Electronics design and Manufacturing Company working as an IOT design partner for Toshiba Semiconductors, Avnet, WPG and many others.

We have a production capacity to support international quality standards of production and packaging at a cheaper rate. We hence requestfuly submit our proposal for your evaluation and reassure you of our quality and promptness. Thanks & Regards Mihir Patel

Hi ! Your proposal looks interesting and we will gladly assist you with it. How about short call in order to discuss all details? One of our managers speaks Hebrew and I hope it will make conversation more comfortable. Thanks Andrew

Hello, I can implement this project quickly because I have very good experience working with esp32. I will implement your project using esp-idf framework from espressif. Master node will connect via BLE to two slave nodes. Each slave node will parse some input from serial and send characteristic notification (or indication) to the master node when found relevant data (I need specification how to parse relevant data from input). Then, master node will send received data using some protocol (which one? http, mqtt, something else?) via wifi, and display data on LCD screen connected using I2C. I have all required hardware for this project (handful of esp32 modules, two modules with already connected LCDs - m5stack and esp wrover-kit), so, I can start work immediately. Estimated timeframe is 10 days, but I will send (or push to your git) working intermediate versions each 2-3 days. Also, I prefer to split payment into two milestones: first when beta version with most functions will be delivered and second final payment after final testing and final product delivery. Regards, Oleksandr Movchan

Hi. I’m a engineer of developing electrical devices , embedded software and service programming. I have designed several devices and have a lot of experience with PIC,AVR，ESP32, ARM and Raspberry Pi. Especially I have accumulated a lot of experience from the prototype design of various hardware device. I also have experienced a project similar to your project. You could realize your idea at a time , we can guarantee high quality of results. Regards.

I have 2 years experience on esp3.. Series.........

We are an company that focus on IOT and communication technologies with a team of 10 electronics engineers and 5 software engineers who work hand in hand to develop smooth driving systems. Also we are capable of manufacturing devices on a large scale with plastic moulding and pcb manufacturing and assembly. Since we are new to freelancer we would like to offer this project at a negotiable discounted price.

Sir I am student I hope this project help me to improve my skills and this skills help to finishing your next project..........

Hi there, Please, invite me to interview to discuss in details of your project. It will be nice to know more info I have had similar projects with ESP32 Looking forward to hearing from you. Thanks.

Soy ingeniero mecatrónico por lo cual de entrada soy 100% calificador para este tipo de proyectos ya que mi carrera se basa en este tipo de proyectos. A lo largo de mi carrera realice varios proyectos muy similares a este por lo que cuento con mucho conocimiento del tema. He trabajado con micro-controladores PIC de la compañía microchip, al igual que con arduino. He realizado diversos proyecto en PCB por lo que se desarrollarlos y diseñarlos en placa para su impresión.

i have worked previously on esp32 and i would love to do this project again .

I have an extensive experience with microcontrollers of several families, such as LPC1768, ARM Cortex M0, M3 and M4, TM4C and of course, ESP32. I have utilized microcontrollers for several purposes, such as motion control, image acquisition, remote data sensing and human-machine interfaces. For most of these applications I have designed and built the full stack of physical information flow: from data acquisition and conditioning through processing up to presentation/visualization on a Graphical User Interface. Granted, I have also built for the inverse flow: specifying desired outcomes on a GUI and effecting them in the physical world by means of an electronic device. For these constructions I make use of a wide range of technologies, such as C++, Python, ZeroMQ, PostgreSQL, MongoDB and Django. For this particular project, I wouuld need from you some details, such as your devised byte frames for data exchange among the ESP32 devices and your chosen LCD display for presentation of the data. Once we have synchronized on these issues, I can get to work and come back to you with a complete implementation. Of couse, the implementation would have been physically validated on a prototype I build with the incumbent device references.

I don't like to tell story to convince .
