  • I’m using these for a school engineering project, and I’ve been through 3 of them (they seem to be quite easy to break), and now that I’ve gotten two of them working and communicating, it’s not reliable at distances over 1m. This seems like a pretty catastrophic failure, any ideas or common mistakes that I could be making? There’s no way that these devices would be this popular if they weren’t dependable.

No public wish lists :(
