Hello,
I’ve been trying to get started with my first node since this spring.
My garage is a bit further away and the status of it’s doors is what I want to monitor. I have a TTN Indoor Gateway running at the house. I’m familiar with Arduino through MySensors for home automation but that’s as far as I’m able to code - or understand it.
I decided to build my first node with an Arduino Pro Mini 3.3V and RFM95 module. I have microswitches that monitor the garage doors. I built the node per: https://www.thethingsnetwork.org/labs/story/build-the-cheapest-possible-node-yourself
And borrowed and modified code from: https://github.com/tijnonlijn/RFM-node/blob/master/PIR_example.ino

// LoRaWAN end-device address (DevAddr)

My first and foremost problem is that Arduino IDE 1.8.10 doesn’t compile.
I have problems selecting and installing LMIC -library and what other lib’s are needed.
I have researched the forum, but can’t find a good answer or at least one that is current. Most LMIC librarys say “modified” from IBM LMIC - but IDE says “invalid library” or if I move the files to the library the compiler turns up a LOT of errors.
Can someone help me make the code above work or give me some pointers?
