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 https://github.com/veonik/Arduino-cc1101 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.
