I need to comunicate up to 32 nodes (esp32) to a single station / root (Esp32, Rasp whatever you recommed me) I have preference to use esp32 features (esp now - esp mesh - lr mode) but if you have an alternative solution (with aditional hardware) will be accepted as well Please, don't put commercial or generic text in the proposal I will not reply, tell me I little about your possible solution and experience about it - Expected range: ~150 meters (repeaters?) - Lora or 433/868Mhz is discarded due Duty Cycle - Root will broadcast a 2Kb message every second - Nodes will send 200bytes message to root every minute or less (need ACK, message must to be recieved) - Nodes will be in movement most of the time, 0-60km/h and will exit coverage area at some point - There is no control about when nodes talk to station, there is a chance that even all nodes talk in the very exact moment - Nodes has size and power restrictions, small as possible and powered by battery - Root has NOT size and power restriction At the moment I only need advice on the hardware (no codding) and I am looking for someone with real experience on the solution, I do not accept people who talk about theory / paper specs witouth previus field testing

Hello, I am Anthony from Sri lanka. I have 7 years of experience in the field of electronics. Currently I am working as a full time freelancer and I have state of the art electronic lab. Why you should hire me ?? *** I have state of the art electronic workshop. *** I have worked with many micro controllers and modules. I have developed my own libraries to work with most of popular modules. *** My workshop is equipped with, ** PCB printing materiels ** 3D printing (Both DLP & FDM) **Various kinds of breakout boards **Qualified developers *** At some point after creating the prototype, if you are willing to take your idea to commercial level (mass production) I can help you with that since I have many reliable contacts in China. I would like to start working with you in order to bring your idea into reality. Please contact me if you are interested. We can discuss more. Thank you Anthony

Hi, I read your project details ... and you need a practical solution not theory. Solution is here... 1--WiFi Communication will be used for this project. 2--You can connect multiple ESP32 to Raspberry Pi based Hub on local network and can be accessed via internet. 3--MQTT protocol can be used for communication and each ESP will have different client ID. 4--Raspberry Pi will work as MQTT Broker and Message handler with Dashboard to send and receive messages. Practical Example will also be provided before start. I am an Embedded Engineer by the way. Leave a Message for practical example. Thanks.

hi we can achieve your requirements by using wifi mesh network as you know esps wifi can not send data directly 150 meters so we re route the data through other nodes which are in between the server and target node this may take sometime to reach data to server but it can be done I have done this with and Lora communication it can be done with wifi and also with BLE using mqtt protocol let's connect and discuss in details thank you

Hi I'm interested in your offer because of the challenge it means. I am dedicated to carrying out projects since the creation of the solution, development and manufacturing PCB (Proteus and Ares), programming, assembly. The projects have involved data collection with sensors of all kinds from environmental to physical in the industrial area. With these I have had to work collecting the information either through RS485, USB, RF, WiFi or bluetooth and send it to the cloud via GPRS or LAN. In these I have had to work with Microcontrollers (Microchip, Atmel, Arduino), embedded systems (raspberry pi, owasys, onion Omega). I have been programming solutions for more than 10 years, from the creation of communication protocols to the development of programs. With regard to possible solutions I would like to talk, I would not rule out Lora and another possible solution could be mqtt. But I would like to know more about the project. Also to be able to limit the price and time better. regards
