Open source LoRaWAN traffic simulator

Some of you may have seen this on Twitter a few days ago but I’m sharing here too just in case! I couldn’t find an easy-to-use LoRaWAN traffic simulator so I ended up building one. Of course, TTN traffic can be simulated by using the Gateway server MQTT endpoint but I wanted something a bit more generic, and closer to “real” traffic. For now, only ABP nodes (with FCnt starting at 0) and uplink traffic can be simulated, but OTAA support shouldn’t be too difficult to implement (happy to take pull…

LoRaWAN simulation issues

Hi there! First of all, forgive me if I am writing this new topic in the wrong place, I am newbie here and I was not able to decide where to put this. Anyway, I would like to explain as much as possible the issue I have, and it is related to the Semtech UDP Packet Forwarder communication. I am developing an application to simulate some LoRaWAN devices, and I need to comunicate them to the TTN platform. I downloaded the TTN stack (with dockers), and I was able to set it up properly, since every…

Connect to TTN with a virtual gateway on my computer for testing

Hi everyone, I have one question regarding connection between the gateway and TTN. As of now, I don’t have a gateway so, can I connect to TTN without a physical gateway or by building a virtual gateway on my computer for testing? Is there is any possible way to test the same? Please suggest me in this regards. Thank you in advance. Regards, Sagar

Is it possible to inject data from a gateway, as if it were a device/node?

I have a pi-based (PI-Supply RAK) gateway operating fine, and in it’s location it would be nice to monitor temperature and humidity and report it back to an application of mine. Naturally i feel like I should somehow be able to inject data from the gateway as if it were a node, rather than have to run a second device right next to it to TX to it. I’ve seen some gateways with sensors built in, so I assume it’s perfectly possible- but what’s the best route to doing this?

Send local gateway data as payload to TTN

We are attempting to send the gateway’s temperature, battery voltage, and a few other “sensor” style data via as LoRaWAN payload to the TTN network and preferable have it show up as a device. Is that possible without adding a 2nd LoRa radio module to the gateway, just to have it send to it’s self. We are using the Semtech Packet Forwarder.

Also I strongly recommend you read the LoRaWAN specification, pay attention to MIC and what it does and go to GitHub - Lora-net/packet_forwarder: A LoRa packet forwarder is a program running on the host of a LoRa gateway that forwards RF packets receive by the concentrator to a server through a IP/UDP link, and emits RF packets that are sent by the server. for information on the protocols the packet forwarder uses.
