RE: Re: Home Easy protocols

["Martin Howell" <martin.howell@xxxxxxxxxxxx>]

Good man, Derek, thanks.  Your research supports the generally
accepted
protocol structure, so I must be reading the scope wrong - bizarrely,
when I first tested the receiver it looked as if the HE transmitter was
sending a series of three bursts, but I just checked it again after
leaving it running for a couple of hours and I now see only a single
burst of data with no apparent gap between the wake up preamble and the
data stream.  Odd, but maybe the receiver needs some time to warm up and
stabilize.

You have some links to Arduino code on your site, I've tried both of
these and can't get any life out of the box at all.  Have you tested
them at all?  Its probable that I'm doing something wrong but it would
be good to know if anyone else has made these bits of code work.

Thanks again
Martin

I've done a fair bit of work in decoding the various HE protocols.

Cheers,
