To promote Republic of IoT (RIoT) hackathon, we do roadshow to few cities in Indonesia and this time in Bogor. Here, I talked about technologies will be used during hackathon, especially LoRa and ESP32.

18. 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

19. 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 MHz
14 dBm
Japan 920 MHz
Malaysia 862 to 875 MHz
20 dBm
Philippines 868 MHz
Vietnam 920 to 925 MHz
India 865 to 867 MHz
Singapore 922 MHz
Thailand 920 to 925 MHz
Indonesia 922 MHz
ANZ 915 to 928 MHz
Taiwan 920 to 925 MHz
China 470 to 510 MHz 17 dBm
919 to 923MHz

20. 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

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!

35. 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);
