I want to learn and play with LoRa. It's a 'IoT' technology that allows you to communicate over long distances using amateur (unlicensed) radio bands. Some of my friends have achieved distances of over 40km, and I'm curious to see what I can do with it.
So far I've been able to get a ping between two modules over a 10m range. Next up I'd like to transmit some useful data over longer distances (temperature for example), and then move on to devices that provide useful data (eg when a train passes a certain point to see if it's on time).
- Raed667 10y agoI have played with LoRa using Arduinos and an RPi that forwarded the transmissions to a web-service. Going from the 'hello world' ping to data is an extremely easy step using the right library.
- xrjn 10y agoI'm sure it's easy, however right now the range part is where the blockage is: I get a SNR of -11 and RSSI of -107.. which results in just a few meters of transmission. Using a Draguino Lora Shield + Hat combination, with the antenna which was in the box. Dunno what I'm doing wrong - what hardware and library did you use?
- Raed667 10y agoI have used the SX1272 module with the multiprotocol radio shield. https://www.cooking-hacks.com/documentation/tutorials/extreme-range-lora-sx1272-module-shield-arduino-raspberry-pi-intel-galileo/#step3_2 https://www.cooking-hacks.com/documentation/tutorials/extrem...
