Connectivity

Wireless modulation technology

Physical (PHY) layer for long range communications

Operates in the license-free ISM bands all around the world

• 433, 868, 915 Mhz

• Regulated (power, duty-cycle, bandwidth) E.g: EU: 0.1% or 1% per sub-band duty-cycle limitation (per hour)

Sensitivity: -142 dBm

Link budget (EU): 156 dB

We’ll use LoRa

ISM Regulation ISM worldwide regulation 7

Output Power vs Duty Cycle

Countries Frequency band review Max. output power

EU 868 MHz 14 dBm

USA 915 MHz 20 dBm

Korea 900 MHz14 dBm

Japan 920 MHzMalaysia 862 to 875 MHz

Philippines 868 MHzVietnam 920 to 925 MHz

India 865 to 867 MHzSingapore 922 MHzThailand 920 to 925 MHz

Indonesia 922 MHzANZ 915 to 928 MHz

Taiwan 920 to 925 MHz

China 470 to 510 MHz 17 dBm

919 to 923MHz

Communications protocol & architecture utilizing the LoRa physical layer

Data rates are from 300bps to 5.5kbps Has 2 high-speed channels at 11kbps and 50kbps (using FSK modulation)

Secure bi-directional communication

DEMO

Mongoose OS - mJS

load('api_neopixel.js');

let pin = 27, numPixels = 1, colorOrder = NeoPixel.GRB; let strip = NeoPixel.create(pin, numPixels, colorOrder);

function turnNeo(val) { if (val) { strip.setPixel(0 /* pixel */, 92, 34, 56); } else { strip.clear(); } strip.show(); }

turnNeo(true);

Turn on that Neopixel!

Mongoose OS - mJS

GPIO.set_mode(0, GPIO.MODE_INPUT); GPIO.set_int_handler(0, GPIO.INT_EDGE_ANY, function(pin) { print('Pin', pin, 'got interrupt'); let value = GPIO.read(0); print('Value:', value); turnNeo(value); }, null);

GPIO.enable_int(0);

let topic = '/devices/' + Cfg.get('device.id') + '/events'; let message = '{"button": ' + value + "}" ; let ok = MQTT.pub(topic, message, 1); print('Published:', ok ? 'yes' : 'no', 'topic:', topic, 'message:', message); }, null);
