how does the oscillator work

hi @jdesbonnet
Thank you for the great work you have done for helping understand this module. I wonder how the oscillator works. It's said that the copper at the base of the NPN acts as decoupling capacitor（C=εS/d , C for Capacitor, ε for dielectric constant, S for copper area, d for PCB thickness） along with the internal resistance of the NPN, together make an RC oscillator (f=1/2πRC). It seems quite tricky for me.
Anyway, still hoping to figure out how the oscillator works.
