Python Library to Transmit RF Signals via CC1101 Transceivers
$ pip3 install --user --upgrade cc1101
On Raspbian / Raspberry Pi OS, dependencies can optionally be installed via:
$ sudo apt-get install --no-install-recommends python3-spidev
Directly connect the following pins:
C1101 | Raspberry Pi |
---|---|
VDD | 3.3V (Pin 1 or 17) |
SI | MOSI (Pin 19) |
SO | MISO (Pin 21) |
CSn | CE0 (Pin 24) |
SCLK | SCLK (Pin 23) |
GND | Ground |
No resistors required. GDO0 & GDO2 are currently unused.

See examples.
import cc1101
with cc1101.CC1101() as transceiver:
transceiver.set_base_frequency_hertz(433.92e6)
print(transceiver)
transceiver.transmit(b"\x01\xff\x00 message")
In case a PermissionError
gets raised,
check the permissions of /dev/spidev*
.
You'll probably need sudo usermod -a -G spi $USER
,
followed by a re-login.
