nrf52840 can not scan any BLE device or being scanned by nRF Connect on my customer board with example "ble_app_att_mtu_throughput"

With my custom board I can program it, debug it and it output log ok, but just can not be scanned or scanning any other ble devices. 

besides: the code works well in other demo board.

the output log as fallows:

[00:00:00.000,000] <debug> ble_scan: Adding filter on CPS_xxx name
[00:00:00.000,183] <info> app: ATT MTU example started.

Thanks.

Hi paul,

          Thanks for your fast answer.

           I'm sorry for forgetting to tell that my customer board has 32KHz crystal; and finally, after I change the 32MHz crystal from demo board to my board, it work ok , but I don't why that happen, the 32MHz crystal use load capacitor with value of 12pF as the same with demo board.

Glad to hear it is now working....
