Hello gentlemen, developers.
Can you please tell me where in the code I can programmatically correct the center frequency of the channel by adjusting the error of the reference frequency of the quartz resonator?
The situation is as follows:
I bought a new TTGO v2 board for the 433MHz range. EU433 regulation requires setting the frequency to 433.175 MHz. (I can see this in the code for the RadioInterface.cpp) Due to the spread of the clock frequency of the quartz resonator, I see the actual center of the signal frequency in the spectrum - 433.575 MHz.
