Hei Jonas,

it sounds and looks like you found the answer yourself. The application side need to release/start the network core as you state. Let us know if there's anything else we can assist with.

Best regards

Reply to myself.
This example works fine as is but the network core must be activated from the application core.

This can be accomplised with the following little snippet in the application core:

void radio_app(void)
{
  // Start up the network core
  NRF_RESET_S->NETWORK.FORCEOFF = RESET_NETWORK_FORCEOFF_FORCEOFF_Release;
  
  while (1)
  {
    __WFE();
  }
}
