so i'm trying to get a arduino nano 33 iot device to connect to my MQTT server/node red thing.
i'm at a loss for finding information, all the examples i'm finding are using Ethernet, or want some 1 wire switch thing. all i want to do right now is get my arduino to say hello world in node red through the debug window.
is anyone on here using a wireless arduino with there node red/mqtt stuff that can direct me in a place that could help. cause i'm so lost.
alot of the examples are trying to connect to a cloud mqtt thing. i don't have that my mqtt server is running on a pi in my home network. so i don't have username or passwords.
my end result would be to have a bme280 sensor attached to the arduino, and have it transmit data ever 15 seconds to the mqtt thing through node red. am i wrong in this or is it possible or am i going in the wrong direction all togther?
