Target board not working.

None of the ble examples are working with our custom board, its not advertising. Whereas it is working with the Nrf52 DK. PL find the attached schematics.

Hi,

• DEC3 should be 100 pF. It's very important that the DEC capacitors are the correct size for timing purposes. Could you try changing this capacitor. 
• What size is L2?
• Are you able to flash the application  successfully?
• Could you try a simpler example such as the blinky example? Can you see that the GPIOs are toggling?

regards
