I have setup a 7249 gateway and a number of nodes. Everything works wonderfully. Can see the data from the nodes on the TTN console. Now I want to get the data into my Arduino application.
I have read and read and read, and I think I’ve suddenly got it! I have set up MQTT.fx on a RPi and it appears to work, though I haven’t got it to interface to the 7249. Pretty sure I’m across that. I have an application set up on an Arduino Mega + Ethernet shield and I’m pretty sure I’ve sus’d how to get the application to talk to the MQTT.fx.
My q is:- can my Arduino application interface directly to the 7249 MQTT-bridge or do I have to go via the MQTT.fx RPi MQTT to the Arduino application?
I think it’s obvious and the answer is “Yes” but the doc talks about the need for the 7249 bridge to connect to an MQTT and then the application.
