I appreciate the intention to share your work.
A few years ago I had wired up two RF95 modules to Photons. I could never get them to work and gave up. I didn’t have Rick’s tutorial, so I didn’t understand what I was doing.
I saw your “Chapter 2” post and started following, thinking about restarting my project. To be fair I should start like you did, by getting Rick’s tutorial working.
Combing through Rick’s thread I also found that someone else posted these examples.
So looks like there are plenty of crumbs to follow nowadays. Adding multi node features will be the next level up. Hopefully someday I will read your how-to guide.
Thanks,
Pescatore
