Garage door opener sniffing via cc1101

I tried reading the wireless signal from a garage door opener marked with a frequency of 868.35 MHz using CC 1101 device with the library and example code provided at The device appears properly connected since I'm getting the version and all. But it doesn't pick up any signals from the transmitter. I changed the carrier frequency to CFREQ_868 and cycled through channel numbers 0 to 9 but the problem persists. What am I doing wrong?

I see the TI chip supports several different modulation types and data rates. Did you try them all?


Keep in mind that most remote garage door openers are encrypted, using a rolling code.
