I believe I was able to download the appropriate addon since I could modify the blink example to turn the relay off an on.
My goal is to be able to turn the relay off and on with an app on my phone. I downloaded the Arduin0BLE library but have not been able to decipher how to connect to the artemis. In a topic on this forum I saw references to version a version 2.0 library, but the only one I could find through the IDE's Library Manage was 1.2.
Need some advice on where to look for help next.
