Whenever I use:
#include <MySensors.h>
on the nRF52832, there is around a 10 second delay between the end of "void startup()" and the beginning of "loop()". Why is that, and what is the MySensors library doing during that interval?
As an alternative, you can define '#define MY_CORE_ONLY' and use ' transportInit(); transportSetAddress(MY_NODE_ID);' to initialize the radio. This dosn't work at the moment with the nRF5. I'm currently looking what the reason is. All radio registers are equal when it's initialized after MySensors normal and my setup(). It's not able to send or receive packages.
Maybe someone has an idea about the reason. Here is my code for nRF5 and other with nRF24.

P.S.: you can reduce the RX/TX time by enabling fast ramp up in MODECNF0 if you haven't to care about nRF51 compatibility.
Thanks for the tip. I tried it both ways. The first scope capture below is taken without MODECNF0 enabled on bit 0, and the second is with it enabled on bit 0.
Have you checked the MODECNF0 register after ramp up? Maybe the register must be changed in a specific state?
