I need to comunicate up to 32 nodes (esp32) to a single station / root (Esp32, Rasp what ever you recommed me) - Expected range: ~150 meters - I have preference to use esp32 features (esp now - esp mesh) - Lora 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 power 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
