Hey, I've some home automation equipment here using the sub-ghz band that I managed to capture with a RTL dongle. From the data sheet and the register settings of the TI CC1100 transceiver chip that is used inside the device I figured out the RF parameters used, i.e. 102kHz channel bandwidth, 2-FSK modulation, 19.2k baudrate, syncbyte etc.
Attached is a screenshot of a GRC waveform I used to capture the preamble of a single packet. Channel 2 is simply the output of a quadrature demod block connected to a scope GUI block. I'd like to decode that into a sequence of bits to run preamble detection etc. I've seen a few OOT modules that do similar stuff but was wondering if there is a GR'ish way to this, maybe a set of generic blocks that could be used for that?
