experimental ble blinky doesn't work

Hi everybody, I have an issue with my application, I use the nRF52832-QFAA with the following circuit, when I open the application Nordic 'nRF Connect', I detect the ble when I use the example from Nordic 'experimental ble blinky' with the devellopment board (PCA10040) but when I program my application with the Jtag I can't detect the device, I don't know if this issue come to the antenna, do you have an idea why it doesn't work ?

Thank you for your help image description image description

  • Thank you for your response Jorn, I noticed that I have an issue with the footprint of my 32MHz crystal, I think this is the problem. I have done it again without ceramic antenna but with the same antenna that the board devellopment Nordic nRF52832 PCA1004. I use Coplanar waveguide to get an impedance of 50 Ohms between the antenna and the first inductance, Is there a specification for the line between the inductance and the capacitor ?

    Do you think that this pcb is correct ?
