The solution I need First: Identify RF modules, stack and circuit that can provide a A server/master that will talk to all the clients, send them commands and receive data back from them. Take commands from a Serial UART Maybe queue commands to clients Send commands to clients when they wake Receive data from clients when sent Battery powered Nodes(s) that will operate on a 2000ma Lipo battery Operate on the lowest possible power Receive commands within a response time of 250ms Send back some random data to simulate sensor input Turn On / Off an LED to simulate command input To be used in the 433 or 915 or 2.4gz bands in Australia Evaluated In order of priority Node power consumption, expected battery life from 2000ma 4.2 Lipo C or C++, Needs to use a toolchain that is Free Hardware any RF module that has a price point of less than $US18 per device Arduino IDE Compatible

hi! I've Farrukh from Xekera Systems inc., we here at Xekera are using bgm121 for our RF devices, this is BLE device, in our last project, we used just 110mah battery and that can last up to a month, we have a team of expert embedded system developers and we know best software/hardware practices to be considered for embedded system projects. can you please share few details? 1. who will be sending serial data? do you already have some other software that will send serial commands to master? 2. may be involve internet in this work? why need direct connection between master and sensor nodes? why not master just push data to some online server(mqtt for example) and clients get data, 3. can you please share overall requirement? so I can give you best suggestion, thanks and looking forward, Farrukh

@AndrijIN

Hello there, The RF module to be used and the technology itself hardly depend upon the working distance and amount of data to be transferred, in other word the connection speed. For example for short distances (less then 50m) BLE is really good and a lot of inexpensive modules available down to 5 USD or even less. For longer distances the LoRa or a similar technology is the choice, or even a more simple RF transceiver, working on 433 MHz or 915 MHz frequency band. But this depends upon security considerations. Do you need the connection to be secured and encrypted or not. All other options from your description could be adjusted to the selected connection technology. So, once again, the working distance and the connection speed is the key you must define here.

I am a UK based developer with my own small limited company. I have developed and supported: > RFM69 based Iot Nodes > LoRaWAN IoT Nodes > Bluetooth Nodes ( RN4020 / ESP32) A basic question does BLE4 have the range you need? Also doe the target price include the pcb/micro? I develop a system that it would work in Arduino and both Atmel Studio - this allows for debugging when you need it! It would be a custom designed PCB similar to a Arduino MKR ZERO and It can take following modules: > RFM69 FM radio Module > RFM65/96/98 LoRa/FM radio Module USB connector Optional pads for > MicroSD connector > I2C eeprom > SPI FLASH > LoRaWAN approved modules RN2483 Best to chat more about these details

I have previously designed ble devices. Assuming you would like to send simple commands to clients and receive telemetry data that is a couple of bytes from each client. If that is the case BLE is a viable choice. There are two things to consider though, - distance between slave/master - how many client nodes will there be please drop a line over chat for further discussion. best regards,

Hi there, I’d like to be considered for IOT node project I have already experienced with this type of project with LORA WAN, custom RF Module Project (cheap rf module with good long distance-si4463 master & client ). If you compromise the distance between master and slave ,you can use BLE with ESP32 . . I can guarantee that this project is within my previous knowledge limit and assure you with delivery. I’m a embedded firmware developer with a strong background developing various microcontroller and socs ,with differnt sensors .I can help you with this project to accomplish your task. For 11 years I’ve worked in embedded and software industry and so I am accustomed to working with all sorts of products and services, and in a variety of industries. I have a deep passion for research and guarantee that all of my work will be genuine.
