Good afternoon,
I am debugging the nRF9160 in a product, and what we are noticing is that the socket "poll" events do not appear to be generated when the system is in...
If you look at the circuit of the PCA10040, it uses a 32Mhz 12pF crystal.
C1 and C2 of the crystal are 12 pF.
However, you say to use this formula: C1 = C_L * 2 - 4pF...
