This means that there are SPI pins on the GPIO that you can no longer use for other purposes. It must be noted that the nRF24L01+ chip is connected to the ATmega328P chip directly on the board. This means you can do a direct MCU swap on existing projects or prototypes using the Arduino Nano R3 dev board, for Nano-RF dev boards.

There is certainly no shortage of choice in this area, either!įrom the most simple modules, such as the 433MHz HC-12 UART radio, to the slightly more complex nRF24L01 SPI, or Bluetooth (JDY-33, DW-CT14, AT-09 etc), or WiFi, or LoRa, or even GPRS/LTE… the options are practically limitless.Īs you can see, the Microcontroller specifications are identical to the Arduino Nano R3 development board. Readers with more experience working with Arduino and other MCUs will very likely have experienced adding radio modules to their devices.

We have, at times, gone so far as to build line-of-sight optical laser communications into our devices, sometimes even with optical repeater devices necessary to span distances of multiple kilometres, where low-latency is a concern. No, seriously! More than half of all of the projects we develop require multiple devices to communicate without wires, sometimes over vast distances. We here at Flowduino build a lot of wirelessly interconnected devices. So, please enjoy this Review-Tutorial (“ Reviewtorial?”) The Problem… Where most publications produce Reviews as strictly-informational articles covering a particular product or service Flowduino is all about education!įor this reason, we present every Review with at least one Tutorial element.Īfter all, how better to review a Microcontroller, Sensor, IO device, or Development Board than to walk through a project using them? Radio.Before we begin, we want to briefly explain the format of this Review article. lostConnection() function will handle the lost connection to prevent unwanted behavior.loop() function will take care of listening for the payload and handling it.setup() function initiate the module as receiver with the provided configuration.The connection will be considered as lost after INTERVAL_MS_SIGNAL_LOST milliseconds. We will be listening for the struct defined in the transmitter (called payload ). Greater level = more consumption = longer distance Append ACK packet from the receiving radio back to the transmitting radio NRF24L01 buffer limit is 32 bytes (max struct size) loop() function will take care of updating the payload values and sending them.setup() function initiate the module as transmitter with the provided configuration.We've defined a struct (called payload ) which will be sent every INTERVAL_MS_TRANSMISSION milliseconds. It will include the library with predefined functions to interact with module. Then you can simply use include statement: #include 'RF24.h' In case you are using different Arduino board, it is advisable to check the Arduino official documentation before proceeding. However, pin D10 is a special pin, it must be set as OUTPUT for the Arduino Nano to operate as an SPI master. The CE and the CSN pins can be connected to Arduino Nano D9 and D10 respectively (you can use any pins). We've used Arduino Nano and these pins are as follows: This means that the MOSI, MISO, and SCK pins must be connected to their corresponding pins on the microcontroller. The module acts as an SPI slave, which means that it can only be used with devices that have dedicated SPI communication lines. The NRF24L01 module communicates with the Arduino using SPI protocol. The adapter works identically for both versions and has the same pinout as original boards. This range extender chip along with external antenna helps the module achieve about 1000m. The second version (on the right) integrates the PA, LNA, and transmit-receive switching circuitry. With this version, you’ll be able to communicate over a distance of 100 meters (range indoors, especially through walls, will be slightly weakened).

This allows for a more compact version of the breakout. The first version (on the left) uses on-board antenna.
