RF Interference

I’ve been building some cabinets in the garage the last few days. I noticed that I was missing some data and dropping packets from the RF12 radios. Here is a graph while I was working in the garage. Note the y-axis.

Ouch. That big spike is 19 dropped packets — 19 minutes straight without new data.

Now check out this graph:

So I stopped work around 6:30. Haven’t dropped a packet since then. There have been a few retries but nothing serious and zero data lost.

Just an example how the local environment can affect your data collection.

HereĀ  is today’s action. Pretty clear that those noisy motors wreck havoc on RF transmissions. Can you tell when I stopped working?
