Hi,
We made a custom board with nRF52 and it's BLE radio doesn't advertising, not visible on nRF connect APP. I tested a lot of example, like uart_peripherial,heart rate and nothing happens (the code runs normally). I tested this example too with a laird development board which has nRF52 and there working, I can see the BLE over nRF connect. However exactly the same example doesn't work with our custom board. The interesting part is that the simple beacon example works, but that's the only one. I can see the beacon in nRF connect. (But that's just an example becaon I can't do anything with it)
I'm using internal RC oscillator for both boards, if it means anything. The custom board is based on noridc datasheet, I can provide scheme if needed.
Any ideas where the problem can be?
Thanks.
