What is the simplest radio transciever.

rikotech8 · Apr 23, 2015

Hello everyone,
I have task to create a simple radio communications between two uControllers. That's why I am asking for help. What radio module would you suggest for such application? The requirement is to use a simple communication protocol and well known interface as UART, I2C or SPI something like that. The distance that should cover is about 20 meters. The network will consist of two devices communicating with each other.

How proficient are you with programming the SPI interface?

The Nordic Semiconductor's nRF24L01+ transceiver are readily available in module form on eBay for as little as $2 USD for a pair of modules.

Nordic Semiconductor nRF24L01+

The Nordic nRF24L01+ is a highly integrated, ultra low power (ULP) 2Mbps RF transceiver IC for the 2.4GHz ISM (Industrial, Scientific and Medical) band. With peak RX/TX currents lower than 14mA, a sub μA power down mode, advanced power management, and a 1.9 to 3.6V supply range, the nRF24L01+ provides a true ULP solution enabling months to years of battery life from coin cell or AA/AAA batteries. The Enhanced ShockBurst™ hardware protocol accelerator offloads time critical protocol functions from the application microcontroller enabling the implementation of advanced and robust wireless connectivity with low cost 3rd-party microcontrollers.

The Nordic nRF24L01+ integrates a complete 2.4GHz RF transceiver, RF synthesizer, and baseband logic including the Enhanced ShockBurst™ hardware protocol accelerator supporting a high-speed SPI interface for the application controller. No external loop filter, resonators, or VCO varactor diodes are required, only a low cost ±60ppm crystal, matching circuitry, and antenna.

The Dorji range of transceivers would be a good choice as far as ease of use is concerned.
The new LoRa range is very interesting.
