Long Distance Post

So…. While the test setup for the postbox notification system worked perfectly, to begin with, when I went to test the system for its functional range I hit a not so invisible wall.

Frustratingly, the signals from these little NRF devices are not able to penetrate through more than 1 or 2 walls, especially brick/concrete ones.

If I was only looking at a short range of around say 15 metres, the wall would issue wouldn’t be a problem, but as I’m 5 floors above the postbox in a reinforced concrete building the operating range is defiantly an issue.

This project is going to be put on hold….for a hardware re-think 😦
