Hi dear community,
I recently stared working with LoRa and wanted to start developing with an RPi4 and the HAT by PiSupply which is now equipped with a RAK2247 module.
I played with the Chirpstack Gateway OS images and also with the image supplied by PiSupply for a TTN gateway.
I did a lot of research so far but I really have no idea no why I can’t get my dev system working with Chirpstack.
I tried a full Gateway OS on the RPi and also my favored setup with just the base system and the net server and app server on a different machine (virtual container). Setup went well and everything seemed ok, gateway is online but when I tried to implement my first app with some devices using an RN2483 module troubles started.
I am now running with the TTN image successfully two devices and tested them in about 3km distance and it works, all uplinks are received and monitored in TTN.
Not so if I try the same with Chirpstack. Joining with OTAA works but when the devices send their uplinks there is a 90% drop rate at least. I really have no idea why, maybe someone can give me some hints?
I monitored the Concentratord on the RPi, the packets are not even logged in the log, only from time to time a transmission is received and logged and just some of them result in a process in the app (published MQTT packet and entry in the live view).
TTN works so far but I’d rather implement everything on my own servers so…
Any help appreciated…
