Reading a sensor using a radio like RFM69, CC100, etc

[cburlacu]

Hello everyone,

I would like to try to read a TPMS sensor (works with rtl_433 --> tpms_bmw.c) using a chip like RFM69, cc100, etc... Do you have any hints on how would one take the modulation information, i.e:

        .modulation  = FSK_PULSE_PCM,
        .short_width = 25,
        .long_width  = 25,

and try to configure the radio? (base frequency, bandwidth, channel, baudrate, etc)?

One sample can be seen here: not sure why FSK NRZ is seens as OOK...

Since I had to increase the sample rate to 1Mhz in order be able to read it, I assume the baudrate is higher than other sensors that can be read at 250 kHz for example...
