Advertising issue in nRF52832

I have made a bluetooth beacon based on nRF52832 chip. I am able to write code DeviceDownload\nRF5SDK17009d13099\nRF5_SDK_17.0.0_9d13099\examples\ble_peripheral\ble_app_beacon using segger JTAG edu mini. Platform used is nRFgo Studio. Still my beacon is not discoverable in any of the app i.e., nRFConnect nRFtoolbox, and nRFBeacon. What may be the possible problem?. I have attached schematic and board file for reference.schematic.pdf

    Nothing seems out of the ordinary whit your PCB, you might have a badly matched antenna so the range might not be grate but if you have two devices right next to each other they should connect fine.  The crystal might be improperly loaded which may make the reference frequency for the radio less accurate, this may result in a bad connection since the carrier frequency might be unstable making a connection unreliable and then the radios will not be bale to communicate.

    I will have to aske you to test a different example, preferably the radio test example in the SDK, sett up a unmodulated carrier, then you can use the RSSI-viewer in the nRF Connect for Desktop app to se if there is a RF output form your PCB. 

    are you then able to see if there is radio activity for more than 10 minutes?
