Hello, I've made a hardware base on new nrf52. I followed the exact schematic of eval board and requirements. Clocks seem to be good (32KHz and 32MHz). A mange to mkae a led blink and a PWM output at the desired frequency (same as on eval board). But the radio doesn't seem to work, I have no signal on the nrf master control. Is there any elese to check, knowing that I don't have a spectrum analyzer?
