Hello,
What is the reason why my homemade PCB half passes through NRF_POWER->DCDCEN = 1; after broadcasting DCDC does not work? How do you need to solve it?
We will get a beacon from China. But how do we know if the chip is original? If I can read the unique device id, can I say it is original? Or is there another way?
