Need help getting PCB + CC1101 for transmitting and receiving

Other Hardware Device Hacking
1

I am trying to follow this github: GitHub - LSatan/SmartRC-CC1101-Driver-Lib: This driver library can be used for many libraries that use a simple RF ASK module, with the advantages of the cc1101 module. It offers many direct setting options as in SmartRF Studio and calculates settings such as MHz directly.

It gives you different options for PCBs. The one I have a Wemos Lolin D1 mini and I am trying to connect a D-Sun CC1101 via breadboard.

I followed the schematics from the github for the ESP8266 diagram and checked the SPI pinouts and all appears to be correct. In trying to troubleshoot, the github has a "Debug Service Tool" within the code. Within the serial monitor output I get a "Connection OK" in regards to the SPI, but a little garbage right before it, also the version and register values all show "FF"
Here's a screenshot of what I get and what it should look like:

Any suggestions, advice, help to get this working would be greatly appreciated

it is start message from ESP12 module at 74k baudrate.use other serial or softwareSerial, or ignore it

I'm using the Arduino IDE, connecting the board through USB and selecting the appropriate COM port. When I select the serial monitor option to see output it was set to 9600 baudrate. I'm not sure what you mean by using another serial or softwareSerial? Do you mean a different IDE? different USB port?

I did try a different USB cable to rule out a cable issue, but got the same output. Thank you for your reply and suggestion.

connect without breadboard.

Yes, that is the diagram/schematics I used to connect the PCB and the CC1101. I did as you suggested and connected the two without the breadboard and I am getting the same results. Any other suggestions?

as my NRF24L01+ not works i soldered capacitor 10µF between VCC and GND pins
