Ported from [etrombly's python version](https://github.com/etrombly) of the [LowPowerLab code](https://github.com/LowPowerLab/RFM69). ## Hardware This version tested on a pair of [Adafruit RFM69HCW Radios](https://learn.adafruit.com/adafruit-rfm69hcw-and-rfm96-rfm95-rfm98-lora-packet-padio-breakouts/overview) with this NodeJS code running on a [Raspberry Pi 3 Model B](https://www.raspberrypi.org/products/raspberry-pi-3-model-b/). The default wiring is: | RFM pin | Pi pin | ------- |------- | 3v3 | 17 | DIO0 | 18 (GPIO24) | MOSI | 19 (GPIO10) | MISO | 21 (GPIO09) | CLK | 23 (GPIO11) | CS (NSS)| 24 (GPIO08 CS0) | Ground | 25 | RESET | 29 (GPIO05) See [here for the Raspberry Pi 3 GPIO pins](https://docs.microsoft.com/en-us/windows/iot-core/learn-about-hardware/pinmappings/pinmappingsrpi). The second radio is connected to an Arduino UNO running the code in [frm69_test.ino](https://github.com/AndyFlem/rfm69radio/blob/master/frm69_test/rfm69_test.ino) and connected according to the instrucitons from [Adafruit](https://learn.adafruit.com/adafruit-rfm69hcw-and-rfm96-rfm95-rfm98-lora-packet-padio-breakouts/arduino-wiring). ## Install `npm install rfm69radio` ## Usage Create the module. ```javascript const RFM69 = require('rfm69radio'); const rfm69 = new RFM69(); ``` Initialize the radio. Provide an address for the node and optionally a _16 char_ encryption key. Then, register callback to handle recevied packets. Then, read the temperature of the radio ic. Then, calibrate the radio. Then, send some packets. ```javascript rfm69.initialize({ address: 1, // encryptionKey: '0123456789abcdef', verbose: false, powerLevelPercent: 20, }) .then(() => { console.log('Initialized'); rfm69.registerPacketReceivedCallback(packetReceivedCallback1); rfm69.registerPacketReceivedCallback(packetReceivedCallback2); return true; }) .then(() => rfm69.readTemperature()) .then((temp) => { console.log(`Temp: ${temp}`); rfm69.calibrateRadio(); return true; }) .then(() => { setInterval(() => { const toAddress = 2; console.log(`Sending packet to address ${toAddress}`); rfm69.send({ toAddress: toAddress, payload: `Hello ${timeStamp()}`, attempts: 3, requireAck: true }) .then((packet) => { console.log(`Sent on attempt ${packet.attempts} after ${packet.ackTimestamp - packet.timestamp}ms`); return true; }) .catch(err => console.log(err)); }, 3000); setTimeout(() => { rfm69.broadcast('Broadcast!!') .then(() => { console.log('Sent broadcast'); return true; }) .catch(err => console.log(err)); }, 2000); return true; }) .catch(err => { console.log(`Error initializing radio: ${err}`); rfm69.shutdown(); }); function packetReceivedCallback1(packet) { console.log(`Packet received (callback1) from peer ${packet.senderAddress} "${packet.payload}" RSSI:${packet.rssi}`); } function packetReceivedCallback2(packet) { console.log(`Packet received (callback2) from peer ${packet.senderAddress} "${packet.payload}" RSSI:${packet.rssi}`); } ``` The initialize parameters and their defaults are: ```javascript { freqBand = 'RF69_915MHZ', // 'RF69_315MHZ' or 'RF69_433MHZ' or 'RF69_868MHZ' or 'RF69_915MHZ' depending on radio hardware address = 1, // Address for this node networkID = 100, isRFM69HW = true, // Is High Power radio? Must be true for RF69HCW, RF69HW powerLevelPercent = 70, // Transmit power between 0 and 100 interruptPin = 24, // Pin number of interrupt pin. This is a GPIO number (GPIO24 = pin 18). resetPin = 5, // Pin number of reset pin. This is a GPIO number (GPIO5 = pin 29). spiBus = 0, // SPI bus number. spiDevice = 0, // SPI device number. promiscuousMode = false, // Accept all packets encryptionKey = 0, // Key for AES encryption. Must be 16 chars long or no encryption set autoAcknowledge = true, // Automatically reply with Ack verbose = false, // Verbose logging to console } ``` ## Dependencies - GPIO access and interrupt detection: [onoff](https://www.npmjs.com/package/onoff) - SPI Interface: [spi-device](https://www.npmjs.com/package/spi-device) --- _Source: https://npm.io/package/rfm69radio · Machine-readable twin of the npm.io package page.
