@pumpkinpi welcome to the forum! The flowcharts at https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help/ can probably be useful. You are correct that the radio wiring is ok since initialization works. You are incorrect that a few people has had to use a capacitor. Everyone has to. If not, problems will arise. Maybe not right away, sometimes people are just lucky and get the nodes partially working initially. But the nrf24 radios will fail sooner or later without a capacitor. I understand that the instructions on the radio wiring page weren't clear on this so I have adjusted them.
