Feature Request: LMS6 radiosonde decoding #48

Open Shogoc opened 3 years ago

Shogoc commented 3 years ago

I'd like to request the capability to decode LMS6 radiosondes. Most of the NOAA radiosondes launched in my area are LMS6's. This is a super exciting project because of the lower-cost hardware and I think that our radiosonde tracking footprint could be significantly increased if we could leverage the TTGO hardware.

As LMS6 are going to be phased out in the next 2-3 years and are to be replaced by RS41 and DFM-17, this feature would have an best before date right from its start

It is unlikely that I will implement such a decoder, but of course I will consider pull requests with working decoders for inclusion (if memory footprint is not too excessive, which I don't think). Hardware-wise it should work (for the 400 MHz version), as modulation seems to be FSK.

@dl9rdz I am curious if you have any more documentation for the SX1278FSK library. I have started working on decoding the LMS6 radiosondes. I am having some time understanding how to get the sx1278fsk library to recognize an lms6 packet. I have changed the packet length (300) and sync (\x00\x58\xf3\x3f\xb8).
