As i check all of the instruments , everything is all right , correct wired . I struggle when i wants just capture frequencies , previus steps are everything well done . only final step need figure out what happen ...
there is link which I use while the wiring : ttps://github.com/simonmonk/CC1101_arduino/blob/master/README.md
I have only educational purposes and my homemade project goal is decode my doorbell signal and make interfere with my CC1101 transciever .
thanks in advance !
P.S
From the link:
// These examples are from the Electronics Cookbook by Simon Monk
// Connections (for an Arduino Uno)
// Arduino CC1101
// GND GND
// 3.3V VCC
// 10 CSN/SS **** Must be level shifted to 3.3V
// 11 SI/MOSI **** Must be level shifted to 3.3V
// 12 SO/MISO
// 13 SCK **** Must be level shifted to 3.3V
// 2 GD0

I have already done as this site guided me, but recieving step , I mean final step is problem ... Generally , Cc1101 is working well
How do you know? What is "final step?"
Your best resource is the internet. Search "arduino cc1101" and you will find many answers. First, I believe, is to have TWO CC1101, one for transmit, one for receive. Here is a link from "ElectroNoob" - his tutorials are complete (and sometimes in-depth). Try this one...
What radio frequency band and method of modulation does the doorbell interface use? Please post a link to the doorbell manual or product page.
I accidantly find at my home and i can only share photos... There is no tytles or numbers on the Doorbell , but in Georgia common frequnecy working for doorbell is 433 MHz .
i also search "LK TS05" which is written on the doorbell controller inner .
In Serial monitor I can see that CC1101 is ready for listening , but after pressed of doorbell button , nothing happen , does not react . cc1101 is detected ( it is also new one, buy from China ) .
I will see shared site , thank you !
The CC1101 is narrow band and may not be operating on the correct frequency.
These 433 MHz receivers are very broad band, and might pick up a signal. They are much easier to use.
Your fcc report link gives 321.4Mhz frequency...

Are you sure ? I am not confident ,but maybe that's the reason of my problem
If your doorbell is the one on your link.
It's on the high border of 315Mhz band.
Maybe CC1101 can hear it if you change frequency setting and antenna?

In the manual is written that my cc1101 working area is 387-464 mhz . But I will try anyways . Thanks for attention ... If it will work , I will answer there
A Software Defined Radio (SDR) will be able to determine what frequency the doorbell is using.

I think you are right, you need to change the crystal to go lower than 390mHz.
What's the purpose of the setup, maybe you can do what you want without radio?
I seem to have a similar system. The push button assembly is the transmitter. Then a central unit has the receiver and processor to make the chime or bell sound. The central unit has an FCC ID number. When I ask Google to search that number, it returned a page full of information including the operating frequency of 315.0 mHz.
The OP can do the same, I suspect.
Or, the OP could read reply #9 above
