Design me a Low Power IOT node using BLE or LoRa or RFM69 or you tell me

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

Skills: Arduino, C Programming, C++ Programming, Electronics, Microcontroller
