I takes a lot of cpu to process with LeanDVB, not to speak about real-time on a I-5 2400 overhere…

Help with decoding signal

Hey there,

I recently got into sniffing signals and so I bought a RTL-2832U and a temperature sensor off amazon. Everything works fine - I even got to decode my temperature sensor signal into bits but now I am stuck at interpreting what bit means what.

I am attaching some bits and hope somebody may got an Idea.

The sensor sends temperature and humidity - I already found the humidity bit.

These are signals I recorded with known temperatures.

These signals record a temperature rising from 10.4°C to ~23°C - humidity is ignored as I wanted to find more about the temperature signal.

Weird results with USB extension cord

Hey everyone,

I'm currently testing the signal quality of different receivers under different conditions.

The signal quality slightly worsens when I'm using an USB extension cord (with ferrite beads) - which is to be expected.

When I plug the receivers into my pocket beagle ( Https://beagleboard.org/pocket ), the results are completely different though. Firstly, the base-level of noise is significantly higher than they were on my pc. But as soon as I use the aforementioned extension cord the signal quality improves by a decent amount.

The explanation of this phenomenon might be a simple one, I'm not seeing it though. Any ideas why this is happening and if I can improve results without an extension cord on the beagle?

Thanks in advance!
