BLE difference between nrf51822 CDAB and QFAC

unzeitig

When I tried S110 examples like BLE proximity, beacon and hrs on QFAC, it works without any problem. Unfortunatelly I can not see any activity on pin VDD_PA of CDAB. Is there any difference between both chips from BLE point of view? How to simply debug it?

    There shouldn't be much difference between the two. There would be some difference in the required matching network, but there shouldn't be much difference outside that. Are you able to debug it with keil or another IDE? If you are you could set a breakpoint in the errorhandler and see if it gets called. I assume you are using a custom board? Could there be a hardware issue with your board?
