Decoding GPL telemetry

Post by fraschizzato » Thu Nov 23, 2017 5:17 pm

I'm trying to decode data from GPL telemety device, center frequency is 868,28mhz, by user manual modulation is gfsk. I've grabbed data with rtl_433 with a sampling rate of 102400. I've tryed decode it with gnuradio but cannot find correct value in GFSK demod block. Visualizing it in audacity i think that's about at 1600Bit/s.

Here a link to user manual (in spanish): https://www.google.com/url?q=https%3A%2 ... F3j6XHJb0Q

Here a link to the grabbed data: https://www.dropbox.com/s/06gdtmt8fp4hy ... .data?dl=0

Any help is apreciated
