Details

At SuperConference we went on a journey to discover how to interact with cellular modules at a low level, using AT commands.

During the workshop we ran into some issues preventing most users from completing the project. This HaD project was created to carry on the conversation, to offer support and share updated code.

Hi crew! We had a killer workshop on Day-1 of SuperCon'18. Unfortunately the majority of us did not get our devices communicating with the Hologram cloud.
Good news! I went back, discovered the issue, patched the code and added the ability to receive inbound data.
I've update the GitHub repo with the new code plus added it to this project. Curious to hear how this new code base goes for everyone.

Enjoy!

I'm not a big fan of maintaining instructions across platforms. As this project will likely grow over the next few months, I've decided to pot instructions to the readme.md on GitHub.
