Calibrate from CC1101?

[gitpower2017]

I have found two pages on how to calibrate a CC1101 module.
It here on an approximation method to determine the optimal frequency setting, in relation to the transmitter.
Perhaps this could be adapted to the ESP?

For sure this can be ported to ESP32/ESP8266. I would rather use an RF transceiver with better reliability on frequency/frequency stability. Like the RFM95W/SX1276...
What I can offer is a define to set the carrier frequency in the header file. Or perhaps as a parameter to the begin() method - this would allow you to build a sketch around it which tries different frequencies and records the RX failure rates.

It is important that the CC1101 can be calibrated by offset.
The CC1101 is very inexpensive and is therefore very often used.
I was about a suitable function or special firmware
be pleased

Good morning
I am looking for the wiring to use BresserWeatherSensorReceiver it with an ESP32 and a CC1101.
Here are the pins of my CC1101
1 GND
2 3.3V
3 GDO0
4 CKN
5 SCK
6 MOSI
7 MISO/GDO1
8 GDO2

can you help me connect my ESP32 and my CC1101
Thank you

Optional frequency offset added in #207.
